    • MSR No longer Setting Reactions

      T

      Hello Everyone -

      I have a peculiar situation that I'm hoping to get some help with.

      Running Vera which is still handling my Zwave, MySensors, Zigbee, and still a balance of my Reactors.

      However, I've also been running MSR for several months in preparation for an eventual move off of Vera.

      Vera had one of its meltdowns this morning related to my Opensprinkler plug in.

      After getting that straightened out, I added the OpenSprinkler plugin to HAAS and that's when I started having issues.

      My existing MSR reactors (even simple ones) don't seem to fire their reactions. I can see the conditions go "true". If I manually fire the Reaction, it works fine.

      I do see this a lot in the logs:

      [1.0.2-21350]2022-05-16T19:02:44.518Z <Rule:INFO> Rule#rule-460 evaluation in progress; waiting for completion

      (Various rules - 460 is just an example)

      Is there anything I can do to further troubleshoot?

    • MSR Telegram Messages Stopped Working

      T

      My MSR has been working flawlessly until a couple of days ago when it stopped sending Telegram Messages (or should I say they stopped getting through!). I have updated to MSR version 22004. The reactor.log is updating and is showing no errors:

      I am running MSR on my QNAP network attached storage. Any assistance would be appreciated.

      Just another question...... I would like to post in the HOME HARDWARE VERA section of Smarthome, but I do not have the option to set up a new post. Do I need to request access for this?

    • SSL Certificate for Multi System Reactor via LetsEncrypt

      W

      Details of runtime environment:

      Reactor (Multi-hub) stable-22055-9b40e12 Running as a service on Windows Server 2022 Std 21H2 Connecting to HASS (HASSOS) Is a migration WIP from OpenLuup/Reactor

      A complete description of your objective:

      Using LetsEncrypt, application "certifyTheWeb", retrieve and apply SSL certificate to Multi System Reactor

      A description of your approach/solution/implementation so far:

      Reviewed Config files, can't seen mention of certificate files in there

      Actual Question:

      How do I apply a certificate to whatever web server Reactor uses? I'm familiar with managing certificates on IIS and Apache but Reactor doesn't use either of these and I have not been able to locat ethe config file that Reactor uses for this. Which config file needs editing to apply a certificate? Does it use the computer certificate store or it's own store (e.g. pem files)

      The reason I want to achieve this, other than the general goodness of having everything I can in TLS is that I have Reactor as an IFRAME in my HASS console and as HASS is HTTPS and Reactor is HTTP then the iframe refuses to open.

      Search for "certificate" or "ssl" did not reveal anything relevant in this forum.

    • MSR ZEN32 weird behavior

      R

      @toggledbits
      Hi Patrick,
      Running HASS 2022.5.3
      MSR zwavejs-22126-834c3e9

      Seeing weird behavior in MSR with regards to my Zen32's. Not sure how to capture info that might be relevent but will describe what I am seeing.
      In the example below I pressed scene 001 4 times. It flashed and changed the primary value to "4". The remaining buttons were previously showing the PV as "double" I pushed each button one time and they flashed and displayed the PV as 4.
      zen32.JPG

      In the zwavejs2mqtt debug screen that sequence looks like this.

      2022-05-10 09:38:44.078 INFO ZWAVE: Node 45: value notification: 91-0-scene-001 5 2022-05-10T16:38:44.081Z CNTRLR « [Node 045] received CentralScene notification { "nodeId": 45, "ccId": "Central Scene", "ccCommand": "0x03", "payload": "0x898501" } 2022-05-10 09:38:45.982 INFO ZWAVE: Node 45: value notification: 91-0-scene-002 0 2022-05-10T16:38:45.984Z CNTRLR « [Node 045] received CentralScene notification { "nodeId": 45, "ccId": "Central Scene", "ccCommand": "0x03", "payload": "0x8a8002" } 2022-05-10 09:38:47.807 INFO ZWAVE: Node 45: value notification: 91-0-scene-003 0 2022-05-10T16:38:47.810Z CNTRLR « [Node 045] received CentralScene notification { "nodeId": 45, "ccId": "Central Scene", "ccCommand": "0x03", "payload": "0x8b8003" } 2022-05-10 09:38:48.858 INFO ZWAVE: Node 45: value notification: 91-0-scene-004 0 2022-05-10T16:38:48.861Z CNTRLR « [Node 045] received CentralScene notification { "nodeId": 45, "ccId": "Central Scene", "ccCommand": "0x03", "payload": "0x8c8004" }

      Let me know what other info you would like me to supply.
      I have played around with a bunch of other key stroke combo's and it looks like buttons 2-5 display what ever button 1 is set to.
      Have tested this on 4 different ZEN32's and it is same on all.

    • HASS 2022.5 issue with ZwaveJS in MSR

      R

      Running zwavejs-22118-baab576 in MSR, HASSOS 2022.5.1

      Due to an unreported issue in HASS, when I upgraded the 2022.5 yesterday, it dropped ZwaveJS2MQTT from my HASSOS build. Finally got it reinstalled and it appears to be working the way it was previously.
      MSR is now showing zwavejs down and in entities, nothing is updating.

      Seeing this in the logs:
      ZWaveJSController#zwavejs ws_open caught [Error]Error: connect ECONNREFUSED 192.168.0.16:3000

      Are there additional steps needed that are not mentioned in the manual?
      At a loss to figure out what is causing issue.

    • Global Expression – Reference Error

      wmarcolin

      Hi!

      After several tests, restarting the computer where the MSR is, and the MSR itself by Tools > Restart, I have a persistent error in the logs.

      32d45bc3-51f8-4718-a113-3381e9d7edf2-image.png

      Looking at the global expression (screen below), I see that it is highlighted as an error, however, if I look at two other expressions above that have the same structure, they do not present an error, so I do not think the problem is with the expression's code.

      ca8a7867-4ac7-4f9a-9913-15a80da18f05-image.png

      This expression uses a group, which validates 4 devices of type door sensor, whether the status is true or false, door open or closed.

      "dgc_entrance_open": name: DGC Entrance Open select: - include_entity: - "hubitat>37" - "hubitat>38" - "hubitat>99" - "hubitat>130" filter_expression: > entity.attributes?.door_sensor?.state == true

      I also compared it with other groups, the structure is identical.

      Looking at the 4 devices in this group, I see that all are active in the MSR, have similar variables, are used in other groups and rules that do not present a problem.

      52b099f4-b9c4-46cb-ad3d-c873b09b7e13-image.png

      Looking at the log, I understand that it refers to some object that would be null, at which point I am lost on what to actually look at.

    • Cheapest platform on which to run MSR

      T

      Please can anyone give me advice on a cheap way to run MSR (both initial cost and ongoing electricity cost). I currently run it on my QNAP network drive (which works very well incidentally). However, this draws a constant 35Watts (£90/yr @ 30p/kWh) and given the recent rise in fuel costs I am evaluating the best way forwards. Note, I only really need to turn my QNAP on for an hour a week to back-up my computer data. I understand that MSR can run on a Raspberry PI, but I am not competent with Linux! Thanks.

    • Build 22118 - entity updates

      G

      I just noticed that the new hotness picked up the entities from when I added an integration temporarily to my Home Assistant and popped a lovely info notice into the Alerts pane.

      I know the info is new - but when did MSR suddenly become more real-time with devices being added to hubs? This is great!

    • [Solved] Is there a cap or max number of devices a Global Reaction should not exceed?

      G

      Noticed in the last few nights that my Global Reaction to turn on a mere six lights in the evenings the same two devices no longer turn on. One is a dimming smart bulb, the other is a wall outlet.

      This has been running flawlessly for months - just in the last few nights I've noticed these two devices being left behind and yes, it's always these two devices only.

      "What changed?"

      No Hubitat firmware updates No new devices added to Hubitat list itemTwo MSR updates (the last two, I keep up with the latest) list itemHome Assistant releases (should have zero bearing, HA is nothing more than pretty dashboards) list itemAdded MQTT to MSR

      I did do a z-wave "repair" last night and am waiting to see if this helps.

      Is there any maximum or cap on number of devices that should be included in a Global Reaction?

      *Marked as solved as the question asked was answered. The issue persists but the question was answered.

    • [Solved] Which version of npm should we be running for reactor-latest-22118-0f0772c.tar.gz

      G

      I've borked my install of reactor-latest-22118-0f0772c.tar.gz for some reason and am retracing steps. Running npm i --no-save --omit dev prompted to update npm and I did (current version now 8.6.0). Currently, attempts to load via browser/s (Brave and Safari) result in "This site can’t be reached192.168.1.xxx refused to connect." I am still able to SSH into the RPi.

      I haven't panicked yet but did just pull my config and storage directories - I believe I read where that's enough for a back-up if a clean install ends up being needed.

      So the question of the day: which version of nmp should we be running on for the latest Reactor?

    • Is a global timestamp expression possible ?

      B

      I’ve looked and can’t find the answer which concerns me that the answer is obvious and thats why I can't find the answer to this.

      I’m new to MSR and this is my first post, so please bare with me 🙂

      What I’m trying to do is have a global expression that contains the current time so I can use it in Global reactions as well as Rulesets as part of my syslog messages.

      Example of what I’m experiencing:
      In Expressions, create a global expression: gMyTOD = strftime("%T %D”)
      In Rulesets, in a rule, create a local expression: MyTOD = strftime("%T %D”)

      In that same rule create a Notify type of Syslog.
      Set syslog message to: gMyTOD time is ${{gMyTOD}} and MyTOD time is ${{MyTOD}}
      Trigger the rule.

      The result is that the local expression (MyTOD) contains the correct time but the global expression (gMyTOD) does not update and reflects the wrong time in the final syslog message.

      Is there a different approach I should be using?

      Thank you in advance for any insight.

    • Restart router when it's gone offline?

      F

      Hi!
      Once a month or so, my internet access is lost, and I have to cut the power to the router, to restart it. When I'm away this become a problem, so I thought that if I got a zigbee switch (in Home Assistant), problem is solved. But how do I (MSR) know if it's offline?

      What's the easiest and most effective way to make this work? Do I ping a few websites every ten minutes or so, or is there a better approch? If I'm going to ping, what URL is recommended?

      For information, I have a set up with Asus routers, Home Assistent with zigbee-, z-wave and wifi devices (a total of appr. 150) and every of my 60-70 automation is done by MSR.
      I run MSR ver. 22080-ae7212f (docker on my Home Assistant blue). HA ver 2022.4.6.
      Thanks in advance.
      Take care, you all!

    • MSR for Scene Controllers

      I still have some code running on my Vera that I want to port and it's related to scene controllers.

      I'm mostly using Fibaro's switch/roller shutter and on the Vera side I'm getting sl_CentralScene/sl_CentralSceneAttr, but it seems too fast to be intercepted by MSR.

      What's anyone using? Thanks.

    • Best strategy to get the difference between pulses in MSR

      therealdb

      So, I have a rule set that it's triggered when a local variable changes. Since it's tied to my solar production, it could change very frequently, so I've just added a reset delay to calm it down, but it's not working as intended.

      What I really need is a way to, let's say, define a percentage and define a variable to understand if the new value has changed +/- 10% before going true.

      I've tried a couple of ways, but I'm posting here anyway, in case anyone has found a better way to tackle this. Thanks!

      Perhaps a dumb question. Can I check from Home Assistant that MSR is up and running? I would like to see that in a status page in HA. I can of course ping the other Pi but it doesn't say anything about the MSR status.

    • Notifications from Alerts

      Crille

      @toggledbits Is there a way to get Current Alerts as an entity so I could monitor those and send notifications if needed.
      My usecase is sometimes openLuup crashes and MSR picks that up pretty quick, sending a pushover notification to me would get my attention to restart it.
      Of course there are many ways to monitor connectivity but since MSR already is doing that it would be neat to take advantage of it.

    • Invocable rules via MQTT

      therealdb

      Hey @toggledbits.
      From the docs:

      You cannot control the state of rules via MQTT. Rule state is driven exclusively by the result of its conditions.

      And I'm OK when rules are triggered by something else, but I've built a couple of rules to be used by other rules, to streamline the logic, and it'll be useful to invoke a rule via MQTT. It's probably close to what rule/:id/restart is doing in the HTTP api.

      Thanks!

    • Home Assistant Script, Reaction requires seclection that isnt there

      S

      I'm trying to create some automation so I can control my pool variable speed pump from reactor rather than iAqualink (which sucks). My controller is MQTT enabled so I created several scripts for my desired speeds. (I know reactor has MQTT ability but honestly I read the docs and could not make much sense of it and since I already have it set up in Home Assistant, I figured I would just leverage that instead)

      So I created all of my scripts and tested them, they worked perfectly. The I created a rule in reactor and set running the script as the action. The problem is that reactor is telling me that I have to make a selection. I try to click the dropdown and there is nothing to select. I cant save the rule, the only option is to exit.

      9e0a3147-5058-4893-9860-2f0d759dfe3c-image.png

      Here is my script in Home Assistant. Any advice on how to get this to work? If I am looking at this the wrong way I am open to suggestions (I would rather be able to call a specific action and specify a speed value but I cannot figure out how to do that). Thanks in advance.

    • Installed latest MSR container and host time is wrong

      M

      Hi, I've been using msr for a while now and haven't had timezone issues until today when I updated to latest docker image (latest-22080-ae7212f)

      both docker date command and my local date command show the same time, same timezone, but for some reason MSR shows the host time as 2 hours in the past as a result all my timed rules run 2 hours late.

      my locale is set correctly in the host machine and is bound into the container as well.

      One possible hint I get is maybe this from the container startup log, but other than timezone stuff everything else seems to be working fine and all my settings loaded up just fine.

      Hi @toggledbits it is possible to have an array in the following way

      ["Window 1"]["Status On"]
      ["Window 2"]["Status On"]
      ["Window 3"]["Status Off"]
      ["Window 4"]["Status On"]

      That is, bidirectional.

      How would this array be loaded? Normally we use Variable = ${{ ["Window 1", "Window 2", "Window 3", "Window 4"] }}, how would the array pair be loaded?.

      Then the use, how would be a looping where I want to ask who has "Status On" and it returns me a new array with the part 1, that is the list of "Window"?

      Or another search, I provide the information of the content of part 1, as "Window 2" and it would return me an array with the part 2 "Satus On".

      Is it possible to have something like this?

      Could you give the examples?

      Thanks.

        ${{[["Window 1","Status On"],["Window 2","Status On"],["Window 3","Status Off"],["Window 4","Status On"]]}}
        

        should work
        and to find all Status on's

        each val in testarray : if val[1] === "Status On" then val[0] endif
        

        and to find the value of Window 1

        (each val in testarray : if val[0] === "Window 1" then val[1] endif)[0]

            Expanding the question, suppose the first part of the array is the device ID, like "vera>device1234".

            Is it possible to use the function below to use this same bidirectional array to search for the name, i.e. using val[0] for the search?

            sort( each id in testarray: do e=getEntity( id ), ( e?.attributes?.binary_sensor?.state == true or e?.attributes?.motion_sensor?.state == true ) ? e.name : null done )

            What would the function look like?

            Thanks.

              @wmarcolin I smell an X-Y problem, but I'll go on...

              I don't know what "bidirectionally" means in this context. Do you mean "two dimensional?" Bidirectional refers to movement, for example, forwards and backwards, or up and down, which is a different thing.

              A couple of minor comments to @Elcid 's response:

              ${{[["Window 1","Status On"],["Window 2","Status On"],["Window 3","Status Off"],["Window 4","Status On"]]}}

              Note that this is substitution syntax, not expression syntax when defining a variable. Adjust accordingly.

              each val in testarray : if val[1] === "Status On" then val[0] endif

              There is no === operator in the expression language, it's just ==

              (each val in testarray : if val[0] === "Window 1" then val[1] endif)[0]

              This is better written as first ... of ..., since you only want the one element (which by implication here the key "Window 1" must be unique in the array), and there's no need to keep searching through the array once you've found it (wastes CPU cycles).

              But about that uniqueness for "Window 1"... this is the real meat of my response:

              If the first element of each subarray (row) is unique, then using a two-dimensional array is inefficient (i.e. doable, but not the best choice). Where unique values are present, an object containing key/value pairs gives immediate random access to any "element", without iteration:

              devices = {
                  "lamp1": "on",
                  "lamp2": "off",
                  "lamp3": "on"
              }
              

              In this example, we can quickly determine the status of any lamp without iteration: devices.lamp2 will give us off.

              This can be further broken down with additional data: each value in the key/value pairs of the object can be any data type, so they can be an array or object themselves:

              devices = {
                  "lamp1": {
                      "status": "on",
                      "room": 0
                  }
                  "lamp2": { "status": "off", "room": 0 }
                  "lamp3": { "status": "on", "room": 2 }
              }
              

              We can again quickly get to the state of lamp2 using devices.lamp2.status (result off again). Using devices.lamp3.room tells us that lamp3 is in room 2. Note that in the example code above, I have shown lamp1 with a typical (JSON-style) fully indented with line breaks for readability, but lamp2 and lamp3 are in a more compact form. Whitespace (including newlines) are not significant to the syntax. Use them for readability if you wish, or leave them out for compactness if that's acceptable.

              When you must search within the values, you can still use iteration. Find the devices in room 0:

                  each dev,id in devices: dev.room==0 ? id : null
              

              By using each dev,id, the iterator will provide both the value and the key for each pair in the object. That is, on the first iteration, dev will contain our subobject (itself with keys status and room) for lamp1, and id will contain lamp1; on the second iteration, the subobject for lamp2 is given in dev, and id is lamp2, and so on. The result of the iteration in this case is an array of IDs of objects in room 0: ["lamp1","lamp2"]; you could also modify the iteration to return the data objects (using dev), if that was more efficient for your later use of this expression's result.

              Find the first device that is "off":

                  first dev,id of devices: dev.status=="off" ? id : null
              

              Adding new devices after the initialization is also easy:

                  devices.lamp4 = { "status": "on", "room": 2 }
              

              But this is all data storage theory, and details of an implementation for a problem that apparently hasn't been stated. We need to know what you are really trying to do, if you are asking for help getting it done. As I said, where we stand right now, this seems very X-Y-ish. The post title is also poor quality, and the head post itself breaks a couple of the posting guidelines.

                Hi Patrick!

                Again a Master Class on how to do the right things.

                My use case is that I want to associate each device in my installation with an identification of which group it belongs to (door, window, security, light...).

                The group I will have to make the manual list (I think), so the first step of var1, I understand is the list I have to assemble, and whenever I have a new device, I update this list manually.

                386f4215-433c-4e29-81ea-159c7fca255a-image.png

                Just a note master, at the beginning of your example, I had to put the comma at each element of the array

                I reproduced your examples to test, and I just can't find the error in the example of the first (var4).

                b42bc82d-2277-419e-ac93-a5ad94058b84-image.png

                Now comes the use, to see device names and which group they are in, or even to search the groups. My next step, is to manage when a device has the true state of its sensor, to take actions such as triggering an action/alarm/siren/message according to the group the device is part of.

                7b1bf8f9-184e-4cbd-a7dc-34ffb1b61ab1-image.png

                If you can see, I am looking to work around not using (yet) a database, which we have had in other trackers to empower the information from the devices.

                Now exploring the Master, sorry 😁

                In your last example, you explain how to add one more row to the array, one more element, perfect. Now, is it possible to add another column to the existing array? For example, with the array I created, add a column that already stores the device name? A loop that looks at the devid and then looks at the device name attribute?

                I was forgetting, how do I change the contents of the array, is it possible with Set Variable? I want to change for example the group from DevWindow to DevDoor for one element.

                Thanks.

                  @wmarcolin Well, I'm almost ready to release my first version of dynamic groups... still hashing out a few details. If you urgently need to do all this work, it's certainly a good opportunity to break your forehead on some sticky problems (I'm always in favor of experimentation and pushing limits).

                  First, having var1 be an expression that does an assignment to devices isn't necessary. Just call your variable devices and put in the rest of the expression after the = in your screen shot and be done with it. You can also set up your devices structure more simply. I'm not sure what the extra dev001 and dev002 identifiers are doing for you, but you can (and probably should) just use the entity canonical IDs directly. It will make everything much simpler. Here's is the expression for the devices variable:

                  {
                      "hubitat>15": { group: "DevWindow" },
                      "vera>device_1866": { group: "DevDoor" },
                      ...etc...
                  }
                  

                  Also, if group is the only data you are keeping, there is no value to creating a subobject to keep it, just make the group name be the value of the device's key/ID. But I'll continue with the structure you're trying to use...

                  Anyway, by simplifying the structure of devices, here's what it looks like and how it changes your first three expressions:

                  340a4917-f984-4a19-9112-39e53f13265e-image.png

                  Looking at var2, we need to use quoted identifiers because a canonical ID contains a character (>) that cannot be used in an identifier, so this devices.hubitat>15.group is not valid. The quoted identifier syntax is context["complexKey"] as shown.

                  The var3 expression is simpler, because we're not looking through the extra layer of indirection your structure had introduced, we're looking directly as our descriptive subobjects.

                  The var4 expression is an error in the syntax on my part. The correct syntax is shown, but I've had to embellish a bit here (next release of Reactor for you, so it won't work until I publish and you update).

                  But here's the important part...

                  As for the rest of it, you're making it unnecessarily hard, I think, because entity.primary_value will give you the value of the primary attribute, so you don't really need to care what capability that comes from and go to the work of classifying devices in expressions to try to make that work. There's an easier way.

                  Based on what I see here, now that we understand you are actually trying to accomplish, what you really need to do is set those primary attributes in local_hubitat_devices.yaml, and skip all of the devices complexity you are creating here, and just use the primary_value from the entity in your sort/search expressions.

                  To do the overrides in local_hubitat_devices.yaml:

                  entities:
                    # Entry shows how an entity can have a service added and its name forced
                    "hubitat>76":
                      # Name override
                      name: "Attic Environmental Sensor"
                      #
                      # List of capabilities to add to this device (array)
                      capabilities:
                        - SomeAdditionalCapability
                        - AnotherAdditionalCapability
                      #
                      # Assign primary attribute for this device
                      primary_attribute: "temperature_sensor.value"
                    "hubitat>178":
                      primary_attribute: "x_hubitat_extra_attributes.batteryLastReplaced"

                    Hi Master!

                    Wow, good news that we will have in the MSR capacity, I am your test guy if you need a tester. And I'm aligned with you, I like to explore, learn, go to the limit, even with knowledge limitations, I seek to explore.

                    I will keep the array structure that can put more dimensions, surely I will explore.

                    Aligned from var4, I repeated your instruction and it really follows the syntax error, no problem for now, as I said we are learning and testing.

                    Master I am trying, to follow the correct path, instead of going all the way around creating the array. I edited the file local_hubitat_devices.yaml to test with these 4 devices, and I see that in the capabilities now appears the DeviceGroup, but I don't see in the attributes, or way to add the value.

                    # This file has local definitions/overrides for Hubitat devices.
                    ---
                    entities:
                      # Entry shows how an entity can have a capability added and its name forced
                      "hubitat>NNN":
                        # Name override
                        #name: "Attic Environmental Sensor"
                        #
                        # List of capabilities to add to this device (array)
                        #capabilities:
                        #  - Tone
                        #
                        # Assign primary attribute for this device
                        #primary_attribute: "temperature_sensor.value"
                      "hubitat>15":
                        capabilities:
                          - DeviceGroup
                        group: "Window"
                      "hubitat>67":
                        capabilities:
                          - DeviceGroup
                        group: "Window"
                      "hubitat>98":
                        capabilities:
                          - DeviceGroup
                        group: "Door"
                      "hubitat>99":
                        capabilities:
                          - DeviceGroup
                        group: "Door"

                    09834c78-b201-4a80-8033-50ebe0d0e371-image.png

                    Now I have a question, can I use this same file for the Vera devices? Following the same path?

                    Thanks.

                      You can't make up data. Just because you assign the capability DeviceGroup to the device, that doesn't mean you get to assign the attributes (group) that may be associated with that capability. Hubitat would have to provide the group data from its side -- the values for that attribute still have to come from Hubitat. And that probably won't be happening, because DeviceGroup does not appear to be a valid Hubitat capability.

                        @toggledbits I understand, so in this case for now is to use the array resource that we discussed before, until you publish the news.

                            @elcid actually, for the final search result, it was easier with object/dictionary, but it could have been done by array as well. Thanks, you also taught me how to make an array that will be useful for sure, it always is.

                              You are correct, I'm suffering from holiday brain-fade.

                              @wmarcolin Version 21331 just released has the first release of dynamic groups. It also includes a syntax enhancement to the expression first...in statement to allow a result expression, so it can return something other than what it finds (i.e. it can perform operations on what it finds and return that as a result). This is useful for your var4 of this post, which should be first dev,id of devices: dev.group=="DevDoor": id to give you the ID of the first matching device. But again, I think the combination of primary attribute assignment and dynamic groups is going to be the best way to solve this.

                                @toggledbits Hi!

                                Perfect, you have totally changed the command.

                                first dev,id in var1 with dev.group=="DevDoor": dev.devid

                                I'm going to study the dynamic group, because even though I can compare object or array contents, the usage is horrible. It's very difficult to validate an array inside another one, or to make combined selections.

                                Well, I don't really know the language, so I'm having a hard time. Let's see if the dynamic groups can make something that should be simple easier.

                                I'll return tomorrow with my experiences 🙂

                                  Hi Patrick!
                                  I don't know if I'm doing something wrong, but I followed the following steps to use DynamicGroupController.

                                  1. Stopped the MSR
                                  2. Compared the reactor configuration file
                                  3. Added the new Groups instruction, the one in the file is almost the same as the manual, and below is the one I set up.
                                    - id: groups
                                      enable: true
                                      implementation: DynamicGroupController
                                      name: Dynamic Group Controller
                                      config:
                                        groups:
                                          "low_battery":
                                            name: Low Battery Devices
                                            select:
                                              - include_capability: 
                                                - battery_power
                                            filter_expression: > 
                                              entity.attributes.battery_power.level < 0.35
                                          "tripped":
                                            name: Tripped Devices
                                            select:
                                              - include_capability: 
                                                - binary_sensor
                                                - motion_sensor
                                            filter_expression: >
                                              entity.attributes.binary_sensor.state == true or
                                              entity.attributes.motion_sensor.state == true
                                  
                                  
                                  1. I restarted MSR + Tools Restart + Crtl+F5 🙂
                                  2. Search in Entities and I see that they are created, but without content

                                  1. Check if they are available for action, yes but also without content.

                                  Well, I found this error, and obviously, I don't know how to solve it. What I did? I reinstalled the MSR, using only the config and storage directory, and the result is the same.

                                    The groups would be empty if there were no tripped or low battery devices in their respective groups, so that's not all conclusive; it may be perfectly correct. The groups at least appear to be correct, for empty groups (no entities matched).

                                    The time stamps in your log snippet are unrelated to the time stamp on the entities, so I can't really draw any conclusions from that either. If you post logs, make sure you are posting logs where the time stamps align to the problem you're reporting.

                                    On your conditions, you can't compare an array to an empty string; that's not a valid test.

                                      Ok let's go in parts, what I created in Group is the same thing I do in the traditional way and get the result, see the battery case.

                                      I'm not seeing an error anymore, after a reboot of the MSR host.

                                      But the array is still empty

                                      Any instructions where I can look for something?

                                        The recommended debugging for this would be to start unraveling your criteria and see what it produces. As a first step (don't do this, just read), I would remove the filter_expression and make sure that your selectors are producing the expected set of eligible devices. An easy way to do that is to simply put an "X" in front of filter_expression (i.e. to make it Xfilter_expression), which changes the name of the key and hides it from the code that's looking for it. You could also comment it out, but that would require that you comment each subordinate line as well, which is more work and can be error-prone. Restart MSR after config changes, of course, and refreshes are also recommended (don't need to be hard refreshes).

                                        But, I found an error, and it's pretty subtle. For me, it logged one short line, so it would be easy to miss; I imagine you have it as well. But it's going to require a code change to fix, so I'll release another build later today. I'll also fix the doc issue you PM'd me about.

                                        Also, don't forget that filtering by controller or capability is a good way to quickly remove "noise" from your Entities list.

                                          I debugged removing filter_axpression entirely, and the variables are still empty. I'll wait for your version update and test again.

                                            This is what is showing up in the log.

                                            Would I have to include any additional information in the configuration to not have this problem with null?
