Advice reqeusted to migrate MSR from Bare Metal to Container
T
Good day all, I'm in the process of trying to shut down my 10 year old Linux home server that served many purposes, but primarily it's what I used for my NAS/Plex Media server. I migrated the NAS aspect of the server in November of last year to a true NAS solution (Ubiquti UNAS Pro), which is rack mount and much more efficient than my old tower, which it's only side benefit was heating my home office during the winter. Unfortunately it also means heating my home office during the summer, which were about to be in full swing. I have two things running on this 10 year old server at this point. MSR and pi-hole. I'm running Plex Media Server on Fedora Workstation in Podman on mini PC, which is much more energy efficient than my old tower. My next step is to migrate MSR. I know there are images of MSR out there, and creating it is well documented. I'm going to be using Podman instead of Docker for various reasons, but they work very similar. What I don't know, is what I need to do to migrate my existing Bare Metal installation over to a container. Has anyone done this? Any advice?

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.

Organizing/ structuring rule sets and rules
R
Hi guys, Just wondering how you guys organize your rule sets and rules. I wish I had an extra layer to have some more granularity, but my feature request was not popular. Maybe there are better ways to organize my rule sets. I use the rule sets now primarily for rooms. So a rule set per room. But maybe grouping by functionality works better. Any examples/ suggestions would be appreciated.

I have the following yaml configuration in local_mqtt_devices file x_mqtt_device: set_speed: arguments: speed: type: str topic: "command/%friendly_name%" payload: type: json expr: '{ "fan": parameters.speed }' While this works fine, I'm wondering how this could be changed to "fixed" parameters, as in this case "fan" only accepts "A", "Q" or a numeric value of 1-5?

System Configuration Check - time is offset
F
Hi! I get this message when I'm on the status tab: System Configuration Check The time on this system and on the Reactor host are significantly different. This may be due to incorrect system configuration on either or both. Please check the configuration of both systems. The host reports 2025-04-01T15:29:29.252Z; browser reports 2025-04-01T15:29:40.528Z; difference 11.276 seconds. I have MSR installed as a docker on my Home Assistant Blue / Hardkernel ODROID-N2/N2+. MSR version is latest-25082-3c348de6. HA versions are: Core 2025.3.4 Supervisor 2025.03.4 Operating System 15.1 I have restarted HA as well as MSR multiple times.

Programmatically capture HTTP Request action status code or error
therealdbT
I have a very strange situation, where if InfluxDB restarts, other containers may fail when restarting at the same time (under not easy to understand circumstances), and InfluxDB remains unreachable (and these containers crashes). I need to reboot these containers in an exact order, after rebooting InfluxDB. While I understand what's going on, I need a way to reliable determine that InfluxDB is not reachable and these containers are not reachable, in order to identify this situation and manually check what's going on - and, maybe, in the future, automatically restart them if needed. So, I was looking at HTTP Request action, but I need to capture the HTTP response code, instead of the response (becase if ping is OK, InfluxDB will reply with a 204), and, potentially, a way to programmatically detect that it's failing to get the response. While I could write a custom HTTP controller for this or a custom HTTP virtual device, I was wondering if this is somewhat on you roadmap @toggledbits Thanks!

ZwaveJSUI - RGBWW BULB - Warm/Cold White interfered with RGB settings - Bulb doesn't change color if in WarmWhite state.
N
Hi , I'm on -Reactor (Multi-hub) latest-25067-62e21a2d -Docker on Synology NAS -ZWaveJSUI 9.31.0.6c80945 Problem with ZwaveJSUI: When I try to change color to a bulb RGBWW, it doesn't change to the RGB color and the bulb remains warm or cold white. I tryed with Zipato RGBW Bulb V2 RGBWE2, Hank Bulb HKZW-RGB01, Aentec 6 A-ZWA002, so seems that it happens with all RGBWW bulb with reactor/zwavejsui. I'm using from reator the entity action: "rgb_color.set" and "rgb_color.set_rgb". After I send the reactor command, It changes in zwavejsui the rgb settings but doesn't put the white channel to "0", so the prevalent channel remains warm/cold White and the bulb doesn't change into the rgb color. This is the status of the bulb in zwavejsui after "rgb_color.set" (235,33,33,) and the bulb is still warmWhite. x_zwave_values.Color_Switch_currentColor={"warmWhite":204,"coldWhite":0,"red":235,"green":33,"blue":33} The "cold white" and "warm white" settings interfer with the rgb color settings. Reactor can change bulb colors with rgb_color set — (value, ui8, 0x000000 to 0xffffff) or rgb_color set_rgb — (red, green, blue, all ui1, 0 to 255) but if warm or cold white are not to "0", zwavejsui doesn't change them and I can't find a way to change into rgb or from rgb back to warm white. So if I use from reactor: rgb_color set_rgb — (235,33,33) in zwavejsui I have x_zwave_values.Color_Switch_targetColor={"red":235,"green":33,"blue":33} 14/03/2025, 16:43:57 - value updated Arg 0: └─commandClassName: Color Switch └─commandClass: 51 └─property: targetColor └─endpoint: 0 └─newValue └──red: 235 └──green: 33 └──blue: 33 └─prevValue └──red: 235 └──green: 33 └──blue: 33 └─propertyName: targetColor 14/03/2025, 16:43:57 - value updated Arg 0: └─commandClassName: Color Switch └─commandClass: 51 └─property: currentColor └─endpoint: 0 └─newValue └──warmWhite: 204 └──coldWhite: 0 └──red: 235 └──green: 33 └──blue: 33 └─prevValue └──warmWhite: 204 └──coldWhite: 0 └──red: 235 └──green: 33 └──blue: 33 └─propertyName: currentColor In zwavejsui, the bulb changes rgb set but warm White remains to "204" and the bulb remais on warm White channel bacause is prevalent on rgb set. x_zwave_values.Color_Switch_currentColor_0=204 x_zwave_values.Color_Switch_currentColor_1=0 x_zwave_values.Color_Switch_currentColor_2=235 x_zwave_values.Color_Switch_currentColor_3=33 x_zwave_values.Color_Switch_currentColor_4=33 Is it possible to targetColor also for "warmWhite" and "coldWhite" and have something similar to this? x_zwave_values.Color_Switch_targetColor={"warmWhite":0,"coldWhite":0,"red":235,"green":33,"blue":33} Thanks in advance.

Problem after upgrading to 25067
R
MSR had been running fine, but I decided to follow the message to upgrade to 25067. Since the upgrade, I have received the message "Controller "<name>" (HubitatController hubitat2) could not be loaded at startup. Its ID is not unique." MSR throws the message on every restart. Has anyone else encountered this problem? I am running MSR on a Raspberry Pi4 connecting to two Hubitat units over an OpenVPN tunnel. One C8 and a C8 Pro. Both are up-to-date. It appears that despite the error message that MSR may be operating properly.

I am getting a Runtime error on different browsers when I click exit when editing an existing or creating a new global reaction containing a group. If the global reaction does not have a group I don't get an error. I see a similar post on the forum about a Runtime Error when creating reactions but started a new thread as that appears to be solved. The Runtime Error is different in the two browsers Safari v18.3 @http://192.168.10.21:8111/reactor/en-US/lib/js/reaction-list.js:171:44 You may report this error, but do not screen shot it.

Local notification methods?
CatmanV2C
Morning, experts. Hard on learning about the internet check script in MSR tools, I was wondering what suggestions anyone has about a local (i.e. non-internet dependent) notification method. This was prompted by yesterday's fun and games with my ISP. I've got the script Cronned and working properly but short of flashing a light on and off, I'm struggling to think of a way of alerting me (ideally to my phone) I guess I could set up a Discord server at home, but that feels like overkill for a rare occasion. Any other suggestions? TIA C

    @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?

          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 keys id, 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).

                  @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.

                        9fa5100e-55d7-46e7-8247-bdcf69d9cb21-image.png

                        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.

                            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".

                              Send a Telegram notification with the contents of the local expression value / text.

                                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! 🙂

                                    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:

                                    08ac845c-8a8a-4f68-bf3f-a07bbd7de1cb-image.png

                                    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:

                                    5098f72d-f68a-44fe-adba-9a6e5f6592f1-image.png

                                    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.

                                      I also tried using a Join expression to get some formatted text out of it but I still just get this:

                                      The reason your join() doesn't work as expected is that the array contains objects, not strings. @Alan_F gives an option, but he uses first 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().

                                      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.

                                            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().

                                        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.
