Handling Dead Entities and Renamed Entities
PablaP
Hello all.. been a minute! I recently rebuilt my Z wave network and migrated to a new z wave stick. In order to prevent any downtime I kept my original z wave network up and ran a docker version of Z Wave JS UI with my new controller. This way I could add device by device without having any devices down. I finally moved all the devices over to my new stick today. The final step was to migrate everything from my Docker instance of Z Wave JS UI to the HA add-on of Z Wave JS UI. However during this migration some of the names didn't populate correctly which I later managed to import back into Z Wave JS UI. The issue was in Reactor it is stuck on the default names and the entities are not updating. I removed the controller from Reactor, restarted, hard refreshed, and added the controller back however the new entity names have not updated. Also it seems like the old entities from my previous instance of Z Wave JS UI are lingering and not being marked as dead (I believe a certain amount of time needs to lapse before they're marked as dead in Reactor). My goal is to basically purge all the entities for the 'ZWaveJS' controller in Reactor so it can pull all the updated entity names and only the entities that exist in Z Wave JS UI. I cannot find a quick way to do this, I know entities can be deleted one by one, but with over 100 entities this would take long I am guessing that if I added the controller with a new name in in the Reactor config it would pull the updated entities and names but I think that would break my rules since the entity IDs would change (I made sure to name all the entities the exact same as they were previously to prevent this issue).

[MSR] reactor-mqtt-contrib package for additional MQTT templates
therealdbT
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/dbochicchio/reactor-mqtt-contrib 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

[Reactor] Copy&Paste of Rules
therealdbT
I don't know if I'm the only one, but managing more than one Reactor installs, the need to have some sort of copy&paste for rules has grown on me. While I understand the technical challenges, I'm wondering if a "god mode" where I could copy the raw JSON rule and paste it into another rule could be an advanced, flag only feature that could benefit power users. I know I can copy the JSON file and proceed, but I must stop Reactor and when doing maintenance, it's more clicks to do. Just an idea

[Reactor] Help with screne controller cycling logic
therealdbT
I’ve added a couple of Shelly Wave i4 as scene controllers and I’m planning to add more, since I can just use standard buttons instead of battery-powered scene controllers, which also looks better aesthetically. That said, I’m struggling to figure out how to write a simple rule that cycles between states every time I press a button. Example: Light 1 ON → OFF, then Light 2 ON → OFF. The part I can’t get right is handling the case where Light 1 or Light 2 might already be ON independently of the rule. Maybe it’s just too much sun and relaxation clouding my brain, but any hint would be appreciated.

Stop the MSR by an external switch on Hubitat.
wmarcolinW
Use case: When performing home maintenance, such as air conditioning, I want all rules involving air conditioning to be disabled. To do this, to day, I have a virtual switch that I placed within all rules involving air conditioning, meaning that if I turn it off, none of them work. Then another situation: the water pump system and garden irrigation, another switch. In short, I had to create several virtual switches in Hubitat to disable rules in MSR. Unfortunately, however, I was unable to cover all scenarios, so I wondered if it would be possible for MSR to support a virtual MSR switch, which, when configured in the reactor settings, would function as a general on/off switch for MSR. If it is configured and turned off, the entire rules and actions in MSR stops working, except for the status change reading process, specifically for this switch, which, when turned on, would restart the MSR. Would it be possible to do something like this? Any recommendations from the experts?

Expose MSR entities
CatmanV2C
Probably a really dumb question. Currently I am using the owntracks_sensor for tracking phones being in region in MSR and it works great. Digging around with Home Assistant and toying with some dashboards, is there any way of exposing that sensor to HA trivially? I could set MSR to trip a virtual switch in OpenLuup which can then be exposed to HA (with all my other Vera devices) but that feels a bit in-elegant if I can do it directly. Any thoughts? Apologies if the ask is not clear/ TIA C

Comment in Globa Expressions

I have several Global Expressions that are set by a rule so the definition area is blank. I'd like to add a comment in this area that explains what is setting the value. Commenting in this area breaks the remote setting. Any way to document what is setting the GE?

Unofficial thread for compatibility
tunnusT
As there are statements about compatibility for home assistant versions in MSR new version announcements (e.g. "HassController: Bless Hass to 2025.7.3"), I thought it would be good idea to track other controllers as well. As an example, I can confirm that build "latest-25208-c53e8513" works with Hubitat Elevation C-8 platform version 2.4.2.134 using Maker API. Updates: (the latest versions first in the list) OK: build "latest-25264-2fbe9217" with Hubitat C-8 platform v. 2.4.3.123

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 foolishly let my system wipe all cookies this morning and with it my settings for my MSR home page. Once logged back in I can no longer remove errant panes nor is the + available to add new ones. Brave Browser v1.80.122 (Jul 16, 2025) What have I done?! Will check other browsers on my M1. UPDATE: Safari exhibits same behaviour. I've tried both sans last-four public key entry and with - no change.

Way to search for rules (rule state) in other rules
T
@toggledbits, not sure if this is a feature request or I'm using the search tool wrong. You have a "Search for rule" in the Rules Set tab in MSR. It works nicely to find a rule and bring up said rule, but can it/could it be used for as a "where used?" global search? For instance, I have a fairly large set of rules, divided up into 10 different rulesets. There's easily a hundred individual rules, and many of the rules have Rule State triggers, which of course refer to other rules. Amongst my troubleshooting today, I came across what may have been a duplicate or troubleshooting attempt, but I can't tell if it's actually used as a Rule State in another rule without opening each rule that I suspect it may be a part of. Thanks.

    Not 100% sure this is a bug because I may have an error in my logic but here is the issue I am running into.

    I have created 3 dynamic groups, the first group called "battery_35" filters all battery_powered devices that have a battery_level between 11% and 35%. My second dynamic group is called "battery_10" and it filters the same type of devices but only the ones with a battery_level between 1% and 10%. The third group is "battery_dead" and filters the same type of devices as the previous groups, but only the ones that have 0% battery. Refer to my earlier thread about the specifics of the dynamic group if necessary.

    My triggers are as follow in the screenshot. Basically if the local expression that spits out the devices that match the criteria for one of three dynamic groups changes and the respective dynamic group is false, the rule goes true.

    Screenshot 2022-10-31 at 8.34.16 PM.png

    I have 3 reaction groups, all set up basically the same. I have a condition for each group to only trigger the notify action if the variable that contains the low battery device (either 35%, 10% or dead) changes. I have it set this way to prevent multiple notifications of device low battery and to mitigate the need to create 3 different rulesets for each battery level.

    Screenshot 2022-10-31 at 8.36.40 PM.png Screenshot 2022-10-31 at 8.37.05 PM.png Screenshot 2022-10-31 at 8.38.44 PM.png

    The issue occurs here, if say the "name_battery_10" and/or "name_battery_dead" are empty, and the "name_battery_35" changes (ie a device battery is now between 11-35%) the "35% Battery" successfully (and expectedly) triggers and the notification is sent. However at the same time one of the triggers "name_battery_10" or "name_battery_dead" trigger and those notifications are sent, albeit with empty device names since no devices actually met their filters (haven't found a pattern of which trigger group goes triggers). This only happens if the variable values are empty. If all the variables are not empty I do not experience this issue.

    I think I could mitigate this by adding the same dynamic group condition that's in the triggers section into the reaction groups but before I do this I want to see if this is a bug or incorrect logic. I have included some logs when this issue occurred I do not see any error besides the dynamic group for "offline devices" which I am still figuring out so please ignore that :).

      There's a bug here, but probably not what you think: the changes operator should not be allowed in constraints. It's special, in that it's a reactive operator that can only respond once and immediately when a value changes. After it has declared that a value has changed, that test will not succeed again unless and until the value changes again, so its behavior in a constraint is effectively undefined and nondeterministic. Fixed: next build the changes operator will not be listed as an option in constraint context.

      Instead of using changes again on your group, why not just test to see if your name list is empty/blank or not?

      The group expression errors showing in the log suggest you have a battery-operated device (or whatever matches your selectors) that isn't from Hass (i.e. the x_hass capability isn't present on it). You may need to handle this condition in your expression, which may be as simple as using the coalesce operators in your expression so that a missing attribute doesn't generate an error:

      entity.attributes.x_hass?.state == 'unknown' ||  entity.attributes.x_hass?.state == 'unavailable' || entity.attributes.x_hass?.state == 'none'

        Sounds good, I was pulling my hair out trying to figure out what was wrong. I swapped it for "is not empty" now it triggers as expected.

        I have a question about the time shown stamps shown in the logs, it never matches up with my local time. Its usually a few hours ahead, is there anyway to have that changed to match the time zone MSR is in? It makes debugging a bit easier.
