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 installed MSR on a RP5 bare metal and then copied the config and store files. Everything seems to be on the RP5 but I am missing all global expression and I don't see the controller time.

Hi,
It seems that the widget deletion does not work. I tried to drag the widget to the left (as explained in here https://smarthome.community/topic/1071/deleting-widgets?_=1744037333660)
but it does not delete it. Anyone else experiencing the same problem?
Also the landing page after login is empty and seems be have some JS issues on the dev console:

Good day all,
I have an notification set up for my washing machine to let me know when it's complete. I have a templete sensor set up in HAAS to let me know if it's Washing, in Standby, or off, based upon the power consumption (Shelly 1PM on outlets)
The MSR code is relatively simple. I have a built in false positive attribute for if MSR gets rebooted, because I would suddenly get tons of notifications when I upgraded MSR.
6774565a-06cc-443f-99c1-e71301b33d83-image.png
What I'm trying to introduce, is a way to verify that I just didn't bump the knob on the washing machine when transferring loads from the washer to the dryer, which turns on the display and brings the power above the Standby threshold.
The power goes up to 3.7W for about 4 minutes if the selector knob is bumped/turned.
What would the best way to do this be? I have most of my MSR code set up for a couple of years now, and my coding logic is struggling a bit.
I think I need a power threshold to be substained for a minimum time period (say 2 or 3 minutes, above 10W), before the other triggers can act. What would the best way to do that be?

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 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?

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!
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: currentColorIn 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=33Is 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.
Good day all,
I have a reaction set up, that I use for both troubleshooting and changing home modes when one of my family members either arrive or are leaving. I use the companion app for HAAS on our iPhones, and HAAS reports if the person associated with the iPhone enters or leaves the geofenced area around my home. I'm sure most MSR and HAAS users are familiar with this.
I use this rule set mainly as a condition for other rules, however, as part of troubleshooting, a notification is sent through HAAS to the companion app when the rule becomes true. The problem is that I'm getting notifications now for both arriving and departing simultaneously.

36903cdd-a87f-473b-82ef-af9ef96d3c44-image.png It used to work fine as intended. I'm not sure exactly when it changed, but now I'm getting two notifications when either of these conditions change.
Any idea what could be happening?

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.
Similarly as for local expressions, global expressions evaluate and update fine when getEntity(...) structure is used. However, at least when certain functions are in use, expressions do not update.
Consider the following test case:
Screenshot 2025-03-13 at 16.29.42.png
Even though auto-evaluation is active, value does not change (it changes only if that expression is manually run). MSR restarts do not help.
Screenshot 2025-03-13 at 16.31.43.png
Note: Tested using build 25067 on Docker. I have also a PR open (but couldn't now get details or PR number as my Mantis account was somehow expired?).
Trying to understand what cause a local expresssion to be evaluated. I have read the manual but I am still not clear about it. Using the test rule below, I can see in the log that the rule is being automatically evaluated every time the temperature entity is changing. That is great...
What I am trying to understand is why the expression is not evaluated based on time as well since the "case" statement has time dependencies.
Any help would be appreciated

I am trying to delete a global expression (gLightDelay) but for some strange reason, it comes back despite clicking the Delete this expression and Save Changes buttons.
I have not created a global expression for some times and just noticed this while doing some clean-up.
I have upgraded Reactor to 25067 from 25060 and the behaviour is still there. I have restarted Reactor (as well as restarting its container) and cleared the browser's cache several times without success.

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

Hi,
I'm trying to integrate the sonos-mqtt (https://sonos2mqtt.svrooij.io/) with the MSR and it's coming along nicely so far.
But cannot wrap my head around how to define custom capabilities in MQTT templates. I need this for the TTS announcements and similarly for the notification sounds where I would pass the sound file as parameter.
So this is what I have in the local_mqtt_devices.yaml
capabilities: x_sonos_announcement: attributes: actions: speak: arguments: text: type: string volume: type: int delay: type: intAnd this is the template:
templates: sonos-announcement: capabilities: - x_sonos_announcement actions: x_sonos_announcement: speak: topic: "sonos/cmd/speak" payload: expr: > { "text": parameters.text, "volume": parameters.volume, "delayMs": parameters.delay, "onlyWhenPlaying": false, "engine": "neural" } type: jsonSo the speak action should send something like this to topic sonos/cmd/speak
{ "text": "message goes here", "volume": 50, "delayMs": 100, "onlyWhenPlaying": false, "engine": "neural" }At startup the MSR seems to be quite unhappy with my configuration:
reactor | [latest-25016]2025-02-09T08:19:59.029Z <MQTTController:WARN> MQTTController#mqtt entity Entity#mqtt>sonos-announcement unable to configure capabilities [Array][ "x_sonos_announcement" ] reactor | i18n: missing fi-FI language string: Configuration for {0:q} is incomplete because the following requested capabilities are undefined: {1} reactor | i18n: missing fi-FI language string: Configuration for {0:q} has unrecognized capability {1:q} in actions reactor | Trace: Configuration for {0:q} is incomplete because the following requested capabilities are undefined: {1} reactor | at _T (/opt/reactor/server/lib/i18n.js:611:28) reactor | at AlertManager.addAlert (/opt/reactor/server/lib/AlertManager.js:125:25) reactor | at MQTTController.sendWarning (/opt/reactor/server/lib/Controller.js:627:30) reactor | at MQTTController.start (/var/reactor/ext/MQTTController/MQTTController.js:268:26) reactor | at async Promise.allSettled (index 0) Configuration for "sonos-announcement" has unrecognized capability "x_sonos_announcement" in actions Controller: MQTTController#mqtt Last 10:21:37 AM Configuration for "sonos-announcement" is incomplete because the following requested capabilities are undefined: x_sonos_announcement Controller: MQTTController#mqtt Last 10:21:37 AMThis is probably a pretty stupid question and the approach may not even work at all, but maybe someone or @toggledbits for sure, could point me to the right direction.
Basically the idea is to be able to send TTS messages from reactions using entity actions. I've previously used HTTP requests to Sonos HTTP API (https://hub.docker.com/r/chrisns/docker-node-sonos-http-api/) for the same functionality, but since moving to sonos-mqtt, I need a way to send the TTS notifications using MQTTController. Along with the actual message, volume and delay must also be parameterizable.

Hi, @toggledbits
I just noticed that following a reboot of my raspberry pi, some of the rules, that I was expecting to recover, are not catching up following a reboot. I have made a simple test rule (rule-m6rz6ol1) with only "after Date/time" as trigger and "turn on a lamp" as a set reaction. All my infrastructure is on the same board so Reactor, Hass, Zwavejs, ... are all rebooting.
Here is the sequence of the test case (All time converted to Zulu to match logs):
Rule "after Date/Time" set to 14:05:00z Shutdown on Raspberry Pi at 14:04:00z Power back up at 14:08:00z Rule overview shows true as of 14:08:14z waiting for 00:00:00 in GUIFrom the log I can see that MSR is picking up the rule and knows that the state of the rule has changed from false to true and tries to send the update to HASS but failed with websocket error.
Here is what I see from the log:
14:04:04z shutdown complete 14:08:08z Power up 14:08:13.111z websocket connection 14:08:15:323z Reaction to the light failed, Websocket not opened After there is a series of websocket connection attempt until 14:08:51z where it seemed to be really ready.Back in 2021 we had a discussion (https://smarthome.community/topic/700/solved-start-up?_=1738766986566) and you proposed to add a startup_delay:xxxx and startup_wait:xxxx parameter in the engine section of "reactor.yaml". When I try the startup_delay (this used to be a hard delay), the engine failed to start (I think). I then try the startup_wait:xxxx without any success. Since it wait for the connection status to be up to cancel the delay, it does not do anyting since Hass is reporting the socket up without really being up ( I think...).
Questions:
Did I figured it all wrong? should the startup_delay:xxxxx have worked? Any ideas?Here is the log:
OK now I am stuck. I did add the log but when I submit the editor complained saying that I am limited to 32767 characters. The log from the shutdown to the time the websocket is stable is about 300000 character long. What are my options?
Not a big issue simply a request if easily doable.
The MSR logs files inside the container are owned by root witch is fine however, the permissions are very restrictive. I do not know if there is something wrong with my installation but the logs permission are set to 222 (write only). Even if the docker volume is set for Read/Write the log files are retaining these values.
I go around the problem by doing a chmod 777 on all reactor logs but every time there is an MSR log rotation the permissions are set back to 222. So unless the permission are implemented in the container there is no permanent solution to this (that I know of).
I do not know much about Docker container so I do not know what is involved here.
Can the logfiles permission be simply chaged in the container to at least allow "other" read permission?
Could the MSR log rotation routine implement a chmod to set the permission?
Just a small anoyance
Thanks

@talisker They mention that their web interface uses "AJAX techniques" to update the page dynamically, which suggests there is an HTTP API (they don't say explicitly; it may just be undocumented but could be reverse engineered/guessed). So it seems possible, but you should get some detailed developer documentation out of them before purchase. If it has an HTTP API, you can get what you need through HTTP queries.
I've pondered doing an SNMP interface, but in a year of development you're the first person (I believe) to suggest a device for which SNMP would be a useful comms protocol. It's on my idea list, but not on my schedule.

ESP32 with MQTT to Publish DS18B20 Sensor Readings-Node-RED
In this tutorial, we will explore how to interface the DS18B20 temperature sensor with an ESP32 board and publish the temperature data on an MQTT server using Node-RED. To embark on this project, we need to configure the Arduino IDE for the ESP32 board. If you're unfamiliar with ESP32 or MQTT...
-
@talisker if you use Tasmota, there's also an HTTP API you could call. That's true for ESPHome or Shelly as well.
Right now all my stuff is running thru MQTT (on my own homemade broker) and honestly, it's just fire and forget after the initial setup. MSR can also map MQTT entities quite easily.
-
-
In that case my suggestion for the ESP32 board seems easiest. Haven't been following the MQTT to MSR integration that Patrick is building, but I assume you could just publish the readings from the ESP32 to MSR directly. The ESP32 is about $10 and the google has lot's of examples of code.

There's a plugin for the OW-server that works great. Been using it for years.
-
@a-lurker I took the plunge and purchased an OW server (Ethernet). The system is up an running with my one wire connected devices. I am however having a little problem with the OWServer Vera app on my Vera Plus. On the face of it the app is working and picking up the one wire devices:
However, when I go into the 'Add Devices' menu there are none of the sensors shown - the page is blank:
I did a bit of googling and found the following information: https://github.com/dbemowsk/OW-SERVER_Emulator
I did try uploading the J_OWServer.js file as @dbemowsk suggested, but it did not solve the problem I have with vera not showing the one wire devices. I have no idea what he is explaining is the problem with the original files from the app store.
I appreciate that you don't have a Vera Plus, but if you could make any suggestions as to what to try I'd appreciate any input you can offer!
I guess that unless I get up an running I will need to find another route to pulling the values into MSR.

Pretty sure you can get it to work. Use the most recent version of the plugin here. The plugin in the MIOS App Store is well out of date.
Your screen capture can be interpreted as the following - how many devices to you have attached?
Devices: 14 Chn 1 error count: 0 Chn 2 error count: 0 Chn 3 error count: 0 EDS OW server web pageYou need to do a few luup engine restarts to get the child devices to show up.
You can use AltUi to install the plugin from the Alt App Store: see More->AppStore. Not using AltUI? It's highly recommended.
If I remember correctly, all the one wire devices are created automatically on first run of the plugin. So on my dashboard it says "No new devices to add" as they have already been added.
"J_OWServer.js file as @dbemowsk suggested" - this bug has already been resolved in the plugin at the link above, so please use the J_OWServer.js file that comes with the Alt App store plugin.
Many of the plugins in the MIOS App Store are hopelessly out of date - refer to the Alt App store list. for updated versions.
All else fails; check the log - once again this can be seen using AltUi -> Misc -> OS Command --> Tail Logs

Noted. I rolled back to my vera backup prior to my attempts yesterday. I then downloaded the files from the github link and loaded into my vera.
I had to set up the OW Server device manually (troubles with ALTUI - see below).Your screen capture can be interpreted as the following - how many devices to you have attached?
Devices: 14 Chn 1 error count: 0 Chn 2 error count: 0 Chn 3 error count: 0 EDS OW server web pageI get the following now:
You can see that it does not show the three channels now, but it confirms that I have fourteen devices (which is correct).
You need to do a few luup engine restarts to get the child devices to show up.
I have done numerous Luup engine restarts, but the devices still do not show up in 'Add Devices'.
You can use AltUi to install the plugin from the Alt App Store: see More->AppStore. Not using AltUI? It's highly recommended.
I did install ALTUI, but I was not able to install OW-Server using it. The first time I pressed the install button it thought about it for a few seconds but did not install the OW Server device. Now when I press it I get an error:
If I remember correctly, all the one wire devices are created automatically on first run of the plugin. So on my dashboard it says "No new devices to add" as they have already been added.
The have not been created, possibly because there is an error.....

Looking at the log it says its missing json.lua. This message tells me you are still running the old plugin from the MIOS store.
Not sure what hardware you are using? The old Vera 3 can't access the Alt App store as the comms library is too antiquated. Regardless you can just download the files from GitHub and overwrite the mios ones. Use the Vera user interface (ie not directly with SSH) as Vera compresses the files when you upload them via the UI. In Vera 3 they end up in etc\cmh-ludl as "lzo" files
The latest version of the plugin looks for ten different possibly available json libraries - see this GitHub link.
If you look in (a Vera 3) /usr/lib/lua you may find dkjson.lua, which in this case is a sym link to /mios/usr/lib/lua/dkjson.lua
You can use the command in AltUI --> Misc --> OsCommand -->Find Json to see what might be available to you. Note that this search doesn't always find what's available. But I would expect dkjson.lua is available and will be found and used by the latest version of the plugin.
