Caution: zwave-js-ui docker 11.4.0 is broken
toggledbitsT
About 20 hours ago, the author of zwave-js-ui posted build 11.4.0 of that product, and it contains an error and won't start (at all) under docker. The author is aware and working on a fix. In the meanwhile, stick with 11.3.1 or earlier. Ref: Issue 4401

Shelly Wall Display XL
therealdbT
I don't know if you guys are into dashboards, but I am. For a second home I tried the Shelly Wall Display 2, and while not so big, it worked well over the summer. Since we're remodeling our house, I just swapped my old Fire Tablet (with its own problems) with two new Shelly Wall Display XL. I just removed the standard firmware, and I added mine (https://github.com/dbochicchio/ShellyElevate), forked from https://github.com/RapierXbox/ShellyElevate I just managed to support buttons (this thing has 4 of them) and it's all auto-discovered by Home Assistant and accessible via Reactor. I also have a new build in the works with support for buttons inside HA. I added a bonus Javascript interface sending events (screen/screensaver status, buttons, motion) to automatically drive the dashboard (all doing in HTML+Javascript and monitoring Reactor's variable). This specifical thing excluded, go get one of them, the device has a decent CPU for HA dashboards and blends wonderfully in the decor.

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
Tom_DT
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

  • Reactor Ex Machina
    K kellyjelly32

    If anyone is interested, I will copy/paste my code here for my solution. It builds on the initial "Reactor Ex Machina" from 2021 but incorporates the changes made to MSR since then. I also modified it in such a way to have the OFF switching done individually for each light with definable delays. A bathroom light that way can go OFF after a random 1-5m while the kitchen stays on for longer for example. I made some other changes as well to suit my needs. It works for me, it might not for you.

    You need four "Global Expressions":

    • REM_lights
    #list of all DeusExMachina (now ReactorExMachina REM) lights to control
    #this is an array [ ]
    #every entity in ' ' (apostrophes) separated by , (comma) in new line
    #check entity list to get canonical ID to be used
    #comments start with hash and are ignored
    [
    'hass>input_boolean_testlight', #Test 
    'hass>input_boolean_testlight2', #test2
    'hass>input_boolean_testlight3', #Stephan
    'hass>input_boolean_testlight4', #Stephan
    'hass>input_boolean_testlight5', #Stephan
    'hass>input_boolean_testlight5', #Stephan
    'hass>input_boolean_testlight5' #Stephan
    ]
    
    • REM_dummy (leave empty)

    • REM_cycler_stimulus (leave empty)

    • REM_status (leave empty)

    If you want a light to be more frequently "ghosted" add it multiple times into the list. In my case light5. If you are on HA, you can add via the helper section some virtual toggles as I did to test your setup. Probably also possible on other platforms.

    My rules are like this:
    e1826f8b-27c8-4248-89c3-2790d39dba45-image.png

    Start & Stop rule (via set/reset reaction), the ghost switching on the lights and then for each light a ghost which switches off so I can manage the individual behavior per light.

    The Start&Stop rule:
    47c893f8-0bdd-4829-b906-64a227863fef-image.png ab665d14-6b87-4236-9dee-a6cce644e73d-image.png

    The reset code bit, hard to read/copy from screenshot:

    ${{ each light in REM_lights: performAction( light, 'power_switch.off', {} ); 0 }}
    

    The ghost for switching ON a random element/light from the list:
    b0a190e8-62b0-4ed9-aa55-08485dee378a-image.png 340d6e2f-0eba-48f5-a19d-4bf6590ef812-image.png

    Code:

    ${{ performAction( REM_lights[ floor( random() * len( REM_lights ) ) ], 'toggle.toggle', {} ) }}
    
    ${{ random()*600 + 600 }}
    
    ${{ REM_cycler_stimulus + 1 }}
    

    The light-specific OFF ghost:
    055a3fa0-7b73-4633-b631-76aa858f42db-image.png

    ${{ random()*600 + 300 }}
    

    Some explanation for random function and the values used with it. It randomly generates number between 0 and 1 (example: 0.4739302) The delay time is in seconds. So the above example will create a delay of 300s minimum plus anything between 0 to 10m, effectively a random time of 5m-15m. See what works for you.

    This REM is working well for me and I am now finally ready to migrate it all to HA after many years on my trusty Vera Lite which is about to die of flash memory degradation.

  • Home Assistant add-on
    K kellyjelly32

    I am using the addon for HA, running excellent.
    Finally my dream came true, using the excellent reactor engine to automate all my devices, mix and match rules and technologies.
    Will offload now finally from my rusty Vera Lite to HA...

    Two things: I keep getting the "reminder" to enter the last four digits despite having done it multiple times.
    Can I safely update MSR from within the addon or do I need to wait for an update to the addon?
