Good morning,
I'm trying to figure out if there is a way to evaluate if a command was completed and retry if it did not complete.
I have 14 iBlinds 3.1 z-wave controllers in my home. 95% of the time, they work just fine. Occasionally, I'll get a blind that does not open on the first attempt. When I go into Home Assistant, and manually open or close the blind, it works.
I have 3 reactions set up for each room. One to open, one to close, and one partial open for sun glare. Each of them is set up as below.
5afc9924-4300-4718-9e23-8855c4a3a9fd-image.png
The reactions are set up to wait for 5 seconds before going onto the next blind, so the z-wave network doesn't get overwhelmed.
In addition, the set command to run the reactions has "Wait for completion" checked.

I also have a routine set up whenever a z-wave device reports as non-functional (dead), it'll get pinged to wake it up. This usually works to wake them up.

Appreciate any ideas to make this more reliable.
I'm running:
Reactor latest-24190-bd310acc, Bare-metal on Fedora WaveJSController [0.1.23326] Home Assistant: 2024.7.0I think this feature request could be accomplished with the use of two or more rules, but it would be great if there was a way to wait for an event or trigger to occur before continuing on in the reactions.
For example, I have a rule that will turn on some exterior lights if you arrive home after the porch lights have been turned off. Right now this rule randomly will turn off between 5-10 minutes after the person has entered the geofence. On some occasions this 5-10 minutes isn't long enough, say if you are unloading the car or something. I would like to kick off the reaction, but pause it part way through and wait for the door to close and lock, then continue it on. Hubitat Rule Machine has a "Wait for event" option, but I really want to keep all my logic within MSR.
Good morning,
I'm going through my ruleset this morning, trying to get away from haas>blahblablah entries and completely migrate them all to zwavejs>xx-0 entries where possible.
I have 3 Aeon MultiSensor 6 devices in my home, all USB powered.
When using Haas entries, I see an entry for hass>binary_sensor_guest_bedroom_multisensor_home_security_motion_detection, and motion_sensor.state (primary)
Screenshot 2024-07-25 at 8.25.53 AM.png
Under ZwaveJS, this entry appears to be missing.

I'm fetching certain data five past every hour, but I would like to do it closer to the hour, e.g. 1 or 2 past (but not at the hour).
I experimented with the following rule that almost works (triggers also at the hour which is not the intention). Any advice for a solution?
It would be nice to have an ability to bookmark a direct link to a dashboard item. In my case I would use this feature to access a virtual switch directly.
Hi @toggledbits
Would you please consider adding an extra sublevel in the rulesets?
I have grouped my rules in rooms/ areas. This works great for me, but I would also like to group rules for the same functionality (in a room). This would make the rules easier to find and name.
Please let me know if this is an option. Thanks!
@togglebits I am curious as to why the tilt_sensor.state (primary) = NULL. I believe it should show true or false. I have to use binary_sensor.state instead in my rules.
Again, not sure if this is related to Reactor/ZwaveJSController implementation or the actual Z-Wave JS UI docker version. I have copied, below, the attributes of the tilt sensor in hopes it can help.
Thanks in advance.

@toggledbits,
I have this device attached to my system, but use a DSC panel. If you need testers to move forward, I'm happy to help.
I'm curious what your thinking the use case is for this. I currently have it integrated into HomeAssistant, and it works fine for the most part. The one thing I can't do is bypass zones, which I would like to have the ability to do.
Are you looking at more direct control for the panel, as opposed to having to jump through HA (or another system) first?
Build 21228 has been released. Docker images available from DockerHub as usual, and bare-metal packages here.
Home Assistant up to version 2021.8.6 supported; the online version of the manual will now state the current supported versions; Fix an error in OWMWeatherController that could cause it to stop updating; Unify the approach to entity filtering on all hub interface classes (controllers); this works for device entities only; it may be extended to other entities later; Improve error detail in messages for EzloController during auth phase; Add isRuleSet() and isRuleEnabled() functions to expressions extensions; Implement set action for lock and passage capabilities (makes them more easily scriptable in some cases); Fix a place in the UI where 24-hour time was not being displayed.I have the following ruleset which I though had been working well until this morning when I noticed it's not.
I've put four weather conditions in an in array and one of them is the current weather condition - but the rule is not true. Now the cloud cover percentage is not yet met but this is an or rule so as long as the "Current Conditions" are met then it should go true.
What's the obvious thing I'm missing here? (I've tried spaces/no spaces in the in and no difference.)
Hi,
Running the latest MSR latest-24152-3455578a with the latest HA 2024.6.1. When trying to call a service I get the following in the MSR logs. Is this a version mismatch? I am not seeing anything in the HA logs.

Some background
I'm trying to integrate a Zigbee device into the MSR using zigbee2mqtt bridge and MQTTController. The device in question is a cheap mood light that has following properties that I'd like to control:
I'v already managed to get the switch part working and can toggle the light on/off. Also the brightness value is mapped back to MSR. In zigbee2mqtt it has a value range from 0 to 254, so this the reason for the expression:
expr: 'payload.brightness / 254'Here's the entity definition (don't know whether the type should be something else than the Switch)
zigbee-lidl-mood-light: name: 'Lidl Mood Light' friendly_name: 'Mood Light' type: Switch uses_template: lidl-moodlightAnd the corresponding template (NOTE: rgb_color has not been defined in this example):
lidl-moodlight: init: "zigbee2mqtt/%friendly_name%/get/state" query: "zigbee2mqtt/%friendly_name%/get/state" capabilities: - power_switch - toggle - dimming primary_attribute: power_switch.state events: "zigbee2mqtt/%friendly_name%": "power_switch.state": json_payload: true expr: 'upper(payload.state) == "ON"' "dimming.level": json_payload: true expr: 'payload.brightness / 254' actions: power_switch: "on": topic: "zigbee2mqtt/%friendly_name%/set/state" payload: 'ON' "off": topic: "zigbee2mqtt/%friendly_name%/set/state" payload: 'OFF' set: topic: "zigbee2mqtt/%friendly_name%/set/state" payload: expr: "parameters.state ? 'ON' : 'OFF'" type: raw toggle: topic: "zigbee2mqtt/%friendly_name%/set/state" payload: 'TOGGLE'The problem
In order to control the brightness or the RGB color values, I would have send a JSON payload in corresponding actions. But I have no idea how to define it in the template. The reason why the switch part is working is that the zigbee2mqtt accepts also plain ON / OFF / TOGGLE string payloads in that case.
But the brightness should be controlled with the following payload:
{"brightness": 196}And the RGB color like:
{"color":{"rgb":"46,102,150"}}Here's the link for the documentation (the Exposes part defines the messages).
So how should I define the JSON payload for example for the dimming action? It definitely should be some sort of expressions since I have to map the MSR real value (0...1) to (0...254) for the zigbee2mqtt.
actions: dimming: set: topic: "zigbee2mqtt/%friendly_name%/set" payload: expr: ????? type: jsonAnother problem is the RGB value. I could use the rgb_color capability for the setting but the problem is that the zigbee2mqtt only reports the current color in hue/saturation or xy coordinates.
Here's an example of published message after setting the color:
Topic: zigbee2mqtt/Mood Light QoS: 0 { "brightness":254, "color":{ "hue":240, "saturation":100, "x":0.1355, "y":0.0399 }, "color_mode":"xy", "color_temp":574, "linkquality":96, "state":"ON" }I would have to map those values back to RGB, but is it even possible with existing constructs in MQTTController's templates?
Help would be appreciated @toggledbits

That's probably more appropriate to post on Mantis for @toggledbits, but since I know there's at least @Crille publishing templates, my intent with this post is to open a broader discussion.
Long story short: I'm starting to slowly add new template for Shelly Plus and I noticed I'll end up with a dozen more templates, all similar but simply different in trivial details, all sharing a large amount of code and all needing special cares when fixing bugs/adding features (as the latest wifi_status addition).
So, I'm wondering if it's time to start thinking of some sort of inheritance in templates, where I could just create a generic shelly_gen1 and use it as a base for shelly_relay, and this be used as the base for shelly_relay_power and so on.
I could probably achieve this with some sort of scripting on my side to generate templates via code, but maybe there's a better way of doing this, or it's already on the radar.
I need a handful of victims volunteers to help test previews of the next build of Reactor. A long-standing request was for "a simple login mechanism," but in practice, adding user authentication and competent access control turned out to be a pretty big project with a lot of big changes on both server and client sides. It's a bit more than I'm comfortable testing myself and springing out to everyone at once, so I'd like to work with a small group to put it through "sea trials."
Major changes/features include:
User authentication with hashed password storage; User group configuration with application restriction (admin, dashboard, API); Detailed control over API access, with user- and token-based authentication/authorization; Improvements to the HTTPS service; Improvements to UI coordination with the core for Rules and Reactions.If this sounds like something you'd like to help with, drop me a reply here in this thread or privately.
[Solution: Reactor 24115 is not compatible with MQTTController > 24120]
Reactor latest-24115 bare metal.
All MQTT entities stop working after updating MQTTController to 24142, downgrade to 24120 and they are back. Templates and configured entities has not been changed between versions.
I'm not sure if uses_template should be replaced by ìnclude in entity configuration in reactor.yaml but I guess not, I've tried it and it did not do any difference.
I have not tried to update Reactor to userauth version.
Example entity in reactor.yaml that uses MQTTController included template:
entities: "takflakt_kallare": name: "Takfläkt källare" topic: "Källartemp" unit: "" uses_template: tasmota_generic_relay init: "cmnd/%topic%/POWER%unit%"Any hints? Do you need more info, please let me know.
Log from startup:
I'm slowly migrating all my stuff to MQTT under MSR, so I have a central place to integrate everything (and, in a not-so-distant future, to remove virtual devices from my Vera and leave it running zwave only).
Anyway, here's my reactor-mqtt-contrib package:
![](https://github.com/fluidicon.png)
Contrib MQTT templates for Reactor. Contribute to dbochicchio/reactor-mqtt-contrib development by creating an account on GitHub.
Simply download yaml files (everything or just the ones you need) and you're good to go.
I have mapped my most useful devices, but I'll add others soon. Feel free to ask for specific templates, since I've worked a lot in the last weeks to understand and operate them.
The templates are supporting both init and query, so you have always up-to-date devices at startup, and the ability to poll them. Online status is supported as well, so you can get disconnected devices with a simple expression.
Many-many thanks to @toggledbits for its dedication, support, and patience with me and my requests 🙂
Is the following config correct?
- id: time_series name: "Out temp" capabilities: temperature_sensor: attributes: value: model: time series entity: "hass>sensor_outdoor_temperature" attribute: "temperature_sensor.value" interval: 5 # minutes retention: 20 # minutes aggregate: wma primary_attribute: temperature_sensor.value type: ValueSensorSpecifically, is "depth" directive needed/mandatory here? Reason I'm asking is that I'm not getting a "final" value in MSR, only debug values are shown:
temperature_sensor.units=null temperature_sensor.value=null x_virtualentity.last_request_time=null x_virtualentity.request_failures=null x_virtualentity.template=null x_virtualentity.timeseries_debug=[{"time":1716537360000,"value":22.1},{"time":1716537660000,"value":22},{"time":1716537960000,"value":22},{"time":1716538260000,"value":21.9},{"time":1716538560000,"value":22}]Good morning,
I apologize if this subject has been covered. I did try the search, but I'm not coming up with any topics on my issue.
I'm running userauth-24137-57b41335, bare metal installation on Fedora 39 Server.
I have a rule set up to turn the Eco mode off on my Nest Thermostat when the thermostat is set to Away (Rule State: Away Mode), the user (Driver) presence in my car changes to true, and the destination is set to home.
93804f7c-62d6-42c0-ae04-ff602011a6fd-image.png
This works fine for most days, where I'm headed home from work (commute is about 45 minutes). What I don't want it to do is set change it to Eco mode if my ETA is more than an hour.
There is a sensor/entity for Time to Arrival when the Destination is set. What it appears to provide is the Time OF arrival/ETA, not time until arrival. If it was Time until Arrival, and it was a numeric value, I could simply test if the value is less than 60 and be done with it.
I pulled up the history through Home Assistant for my morning commute and this appears to be what it is providing.
c2a32739-c84f-4a05-95d9-73793ed818f5-image.png
So what I need to do is to do a calculation of the the ETA from the sensor value and subtract the current time, and get a value in minutes that I can determine if it's less than 60.
I believe I can do this with the local expression, but I don't see anything for the system time, or local time. Also, do the local expressions update themselves if the sensors do?
Good morning,
I'm running userauth-24137-57b41335 on Fedora 39, bare metal installation.
ZWaveJSController 0.1.23254
Home Assistant:
Core, 2024.5.3 Supervisor, 2024.05.1 Operating System, 12.3 Frontend, 20240501.1I'm trying to troubleshoot a Dynamic Group Controller and notification alert that I've set up for low battery level.
In my Reactor.config, I have the following lines:
name: "Dynamic Group Controller" implementation: DynamicGroupController config: groups: "zwavejs_dead": select: - include_group: "zwavejs" filter_expression: "entity?.attributes?.zwave_device?.status == 3" group_actions: true "low_battery": select: - include_capability: battery_power filter_expression: > entity.attributes.battery_power.level < 0.35The idea here is that I should only have members of this group that have a battery level below 35%. When I go into Entities, I show a whole slew of devices, none of which have a battery level below the threshold.
a77e445b-ab78-4752-a624-3c4117f34f90-image.png
I also tried setting up a rule to generate a push notification once a day, but with all of the group members, I've had to disable the rule. I believe I have it set up correctly, but I'm not 100% sure. I want the notification to tell me the battery level for that device as well.

Can anyone point to me what I may have misconfigured to get these results?
I should also note I'm only interested in ZWaveJS devices. It's showing me battery status for my iPad and car as well, which I don't need it to send me.
Notifications from Alerts
-
@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. -
Why don't you just condition the
sys_system.state
attribute of the openLuup controller's system entity? -
@toggledbits Because I did not see that when I first looked for it
Excellent, just what i needed, thank you! -
Resurrecting this older thread... does this answer mean there is no way to react to the presence of an alert within MSR? If not, this would be a useful enhancement.
I have a camera that is switched between day and night settings by http requests sent by MSR near sunset and sunrise. Yesterday the camera stayed in night mode most of the day while there was an alert showing in MSR that the http request had failed. I realize I could capture the http response to an expression/variable and then write a rule based on that variable to notify me, but I'd have to do this for every http request in every ruleset, and I'd have to make sure I evaluate the response correctly (which is likely to be a hit or miss operation for me). That still wouldn't capture other alerts that MSR might display outside of failed http requests, but I'd like to push all alerts to my notification system. Basically, I don't want to have to check the MSR interface to make sure it's happy, I'd like it to tell me when it's not.

The
reactor_system.alerts
attribute value is an array of objects. Each element/object contains keysid
,severity
,message
,timestamp
.Here's an expression that would return an array of messages containing the words "HTTP request" in the message field. You can put this into a local expression of your rule.
each alert in getEntity( 'reactor_system>system' ).attributes.reactor_system.alerts: find( alert.message, "HTTP request", "i" ) >= 0 ? alert : null
If the result of the array has non-zero length, an HTTP error has occurred. You can either just wrap the above expression in
len()
or use a second local expression (sometimes it's nice to keep them separate so you can more easily see what it's doing).EDIT: Fixed the match string in
find()

@toggledbits I was playing with this for about an hour, using it as an exercise to try to get better with arrays and the expression syntax. I created a rule that made a bad http request in order to throw an http request error.
I managed to get to a point where I could concatenate all the alert messages into a single string in an expression. That could then have been used in a rule that checked that expression for 'contains HTTP request'.
The expression you posted above seems like a quicker way to get to the same result, so I tried using it, but it doesn't seem to be working for me.
When I remove the 'find' and just return the alert.messge using:
each alert in getEntity ( 'reactor_system>system' ).attributes.reactor_system.alerts: alert.message
I get:
Last value: (array:1) ["Reaction "Test Rule<SET>" (rule-kxkgh72o:S) step 1 HTTP request failed"]
But your full expression from above returns this:
Last value: (array:0) []
It seems like the 'find' part of the expression isn't matching.
However if I create the following expressions:
g_array_alert_messages = each alert in getEntity ( 'reactor_system>system' ).attributes.reactor_system.alerts: alert.message
and
g_str_alert_messages = join (g_array_alert_messages, " | ")
I get a pipe separated string of all the alert messages that I could use in a rule.
p.s. I also learned that if you point an expression at the alerts, and then use bad syntax in that expression, you can easily create a loop and raise the repeat alert counter to 50,000+ pretty quickly. Thank goodness for the throttling limits, since I also have a rule that sends a notification to my phone whenever an alert is raised and that only fired once per minutes, not 10,000 per minute.

Whoops, sorry, the
find()
is trying to match at the beginning of the string, just remove the^
from the find match string. I fixed it in that post and tagged the edit. -

EDIT: Fixed the match string in find()
That works now, it lists the latest alert error for "HTTP Request"
If there are also other alerts errors still listed in that area of the GUI for "HTTP Request Failed" how would you also get those as well in to an expression value ?
Also is there a way to clear / delete a particular error alert via a rule / code ?
Thanks

You're already doing it. The
each
produces an array of all matching values. The result you are showing is just an array of 1 element because there is only 1 match. -
This post is deleted!

Sorry I didn't see that there were two ID's listed in that expressions output. So you are right it does appear to be showing both alerts that contain the words "Http request".

First, it will never be null, so that's not a valid test (I mentioned that here).
For your message text, you probably need to convert it from an array to a formatted string that is actually readable. This has been covered a bunch as well (even in this very thread), so I won't give away an answer... better to practice!

Maybe I can use Variable value "is not empty" instead? As the trigger.
I also tried using a Join expression to get some formatted text out of it but I still just get this:

Here's what I have... I want to be notified on all alerts, and I only want to include the message from the most recent alert in the notification. I also needed to remove the escaped quotes (") from the message string because it was messing with my notification where I was inserting the expression into the http call.
So:
g_alerts_array = get all the alerts
g_last_alert = get only the alert where the timestamp == alert_last timestamp
g_last_alert_replaced = remove the " from the alert message string
I realize there is probably some way to combine all of these into one expression, but I was getting errors when I tried wrapping the "first" and "replace" functions around the alerts array expression.
Then in my rule:
If you only want http errors, then you'll have to modify the above expressions to find only those, as Patrick showed above. You'd also have to use a different trigger, as you don't want to fire the event every time the alert_last changes, as some of those won't be http errors.

The reason your
join()
doesn't work as expected is that the array contains objects, not strings. @Alan_F gives an option, but he usesfirst
so only one alert, not in array, would result.Good efforts all around though. Let's fill in some details...
When writing complex expressions, and particularly as you're learning the expression language, it's often better to break it down into pieces as @Alan_F has done. For what you seem to want to do, you started with filtering the array:
Alerts_HTTP_Failed = each alert in getEntity( 'reactor_system>system' ).attributes.reactor_system.alerts: find( alert.message, "HTTP request", "i" ) >= 0 ? alert : null
This gives you an array of objects (as we've established) of only the HTTP request errors. From there, you want to get to just the message strings, but all of them, not just one/the first, so you'll use
each
again:HTTP_Fail_Messages = each alert in Alerts_HTTP_Failed: alert.message
That simple expression loops over the objects in the array and extracts just the
message
field. The result of that is a new array of strings, rather than an array of objects. From there, join...HTTP_Messages_String = join( HTTP_Fail_Messages, "; " )
And as they say, Robert is your mother's brother.
Doing it all together:
join( each alert in getEntity( 'reactor_system>system' ).attributes.reactor_system.alerts: find( alert.message, "HTTP request", "i" ) >= 0 ? alert.message : null, "; " )
If it looks like I left out a step, I did, in a way... rather than having the filter loop return objects, this version just returns the message (strings) directly as an array, so it eliminates that middleman and can then be passed directly into
join()
.@alan_f said in Notifications from Alerts:
g_last_alert_replaced = remove the " from the alert message string
Although the quotes look funny in the display, I don't think they will bother anything in use, as the notifiers are built to digest/handle such special characters properly.

@toggledbits I'm using a self-hosted notification system (Gotify) so when I said 'send notification' it would have been more precise to say "use as the JSON content in an http post request". The " definitely broke the request when it was substituted in to the middle of the request body. I also tried to urlencode the string but while that didn't break the request, it was super ugly as it passed all the encoded characters into the displayed message. I'm not very proficient at regex, so it took an online regex tester and a bit of trial and error to arrive at the right number of backslashes to finally make it work.
Another lesson learned: turn off 'auto evaluate expression' when trying to write expressions that refer to the alerts, 'cause if you get the expression wrong and throw an alert that causes the expression to reevaluate which throws an alert... I had to restart my Reactor Docker container a few times before I turned off 'auto evaluate' ¯_(ツ)_/¯

That would depend on how you are building it. If you are just jamming it in as a string, that's definitely going to create problems. A better approach may be to build the payload as an actual object in the expressions, and then at the end, right before sending to Gotify, put it through the
stringify()
function, which will convert the object to a JSON string, and that will also handle the quotes correctly to produce valid JSON with the quotes embedded. That will spare you the agony of having to sanitize every string you might ever send.
