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.

          Certainly would expect this if you actually "mowed" it. Sorry couldn't help... 😉

          Have you tried reinstalling as if you were updating and ran an "npm update" ?

            @rafale77 has the right steps to begin: reinstall Reactor as if updating, and then run npm update --no-save in the reactor install directory.

            There is at least one damaged state file, I can see from your log post, so remove all the files in storage/states/. The loss of states may cause some rules to re-run, but once it recovers it should be fine from there. Do not remove files from other directories. Then start Reactor.

            If that doesn't come up, and you don't have a backup, we'll see what we can do to untangle anything else that may be damaged.

              @toggledbits @rafale77 npm Update and erasing storage /states did it. No it is up and running. Does this mean the same could happen in a power outage?

                @matteburk I have yet to test MSR, but I think it may be more of a Raspberry Pi question. Regarding Pi I think there are a few steps that one can take to make the setup more dependable.

                The first step is to run it on a SSD and not on a SD card. SD cards are quite bad at constant read/write and are initially made for e.g. digital cameras. It is very easy to migrate the installation from the SD to a cheap SSD. I do not remember your setup, but if you have not done this I would say it is step number one.

                The next step is to power the Pi via an UPS. The cheapest way is to buy a regular UPS, this is what I have done for my servers. Even the cheapest you can find has ample power for running a Pi for quite a long outage. You can also set it up on the Pi via e.g. PiJuice Hat, but this is more costly. Also the regular UPS can be used to power/protect other devices such as you router, NAS or similar.

                The third step would be to backup the SSD at times. This can be done either via simply cloning the SSD to an image with e.g. Win32 Disk Imager or also setting it up to run in the background on the Pi. I think there are some tips in the forum on how to set up this.

                    Good recommendations all. In terms of architecture, I can personally vouch for using a PoE hat and powering the Pi from a UPS-backed PoE switch. If you have IP cameras, you may already have such a switch. While this is really no different in effect from plugging a Pi's regular AC power adapter into a UPS, it gives you vastly more choice on the location of the Pi, which may be important if you are using a Z-Stick, etc. Being able to distribute stable power over a wide area because of PoE is a huge win. I've also powered my Vera via PoE for a long time now (using a PoE adapter).

                    And, backing up Reactor is as easy as backing up the "storage" and "config" subdirectories. Any way you do that is probably OK. Depending on what else you might be doing with the Pi, it's likely sufficient to back up storage/config often, but make SSD images only very rarely. Even if the image is a year old, an apt upgrade will quickly bring the OS back to current, and then the MSR upgrade and storage/config restore and you'll quickly be back on line in a blink.
