Notice to Docker + ARM Users (RPi 3/4/5 and others)
toggledbitsT
This post does not apply to users of Intel/AMD-based systems. If you are using a Reactor image tagged latest-amd64 or stable-amd64, then this post does not apply to you. It also does not apply to bare-metal installs; it's for users of docker images on ARM-based systems only (principally Raspberry Pi hosts, but could be others). After January 15, 2026, I will no longer produce the aarch64-tagged docker image for Reactor. The ARM images will be arm64 for 64-bit operating systems, and armv7l for 32-bit operating systems. For those of you running a container from the aarch64 image today, this will be a relatively simple change: you just need to switch the image used for your docker container to a differently-tagged image. If you are using docker-compose, then this is a relatively simple matter of changing the image line in your docker-compose.yaml file and then stopping (docker-compose down) and restarting (docker-compose up -d) your Reactor daemon. But there's a catch... not all of you can safely just switch from the aarch64 image to the arm64 image. And, you can't just trust the output of uname -m, for example, because this exposes the CPU architecture, but not the word size of the OS running on that CPU. For Raspberry Pi systems, the transition to 64-bit operating systems was long (starting in 2016) and not always obvious — although there was a first "official" 64-bit OS for RPis in 2020, it did not become a default recommendation in the Raspberry Pi Imager until 2021, and then that was only the default for Pi 3/4 systems with >4GB RAM; it was 2022 before it was universally recommended for all 64-bit CPUs regardless of RAM size. Depending on when you first imaged your RPi system and what default you may have been offered/chosen, you could today easily have a 64-bit CPU Raspberry Pi running a 32-bit version of the operating system. Upgrades along the way would not change this; changing it to fully 64-bit requires a full reimage of the system. To establish if your OS is 64- or 32-bit, log in to your Pi and run: sudo dpkg-architecture -q DEB_HOST_ARCH. If the response is arm64 or aarch64, then you are running a 64-bit OS and you should use the arm64-tagged image. If it's anything else, you are running a 32-bit OS, and you should use the armv7l-tagged image. pi@rpi4-1:~ $ sudo dpkg-architecture -q DEB_HOST_ARCH armhf pi@rpi4-1:~ $ uname -m aarch64 pi@rpi4-1:~ $ In the example above, the uname command reports that the CPU is 64-bit architecture (aarch64), which is true for the host on which I ran these commands, but the DEB_HOST_ARCH value is armhf, indicating a 32-bit operating system. This system has to use the armv7l-tagged image. Other systems will have their own ways of determining the word size of the running OS. Since the majority of Reactor users running ARM systems are on Raspberry Pis, I am able to supply the above instructions, but if you happen to have a different ARM system, you'll need to do some web searching to figure out how to expose that information. Or, you can just try the arm64 image, and if it doesn't start up, try the armv7l image. Remember to always back up your system before making any changes. For everyone, please make this change as soon as possible, and if you have any trouble finding a working image, please (1) go back to the current aarch64 image; and (2) let me know in this thread along with as much detail about your host system as you can offer (including the output of the dpkg-architecture command mentioned above).

Requesting a proper ARM64/aarch64 Docker image (Pi 5 support)
M
Hi, I'm in the process of migrating from a Raspberry Pi 4 (ARMv7) to a Raspberry Pi 5 (ARMv8/aarch64), but I’ve run into an issue: there is no proper ARMv8/aarch64 image available. None of the existing images run on the Pi 5 - they all exit immediately with code 139 (segmentation fault), which typically indicates that the binaries inside the image are not compatible with the ARM64/aarch64 architecture used by the Pi 5. Would it be possible to publish a correct ARMv8/aarch64 (linux/arm64) image? Building one should be relatively straightforward using docker buildx with multi-arch support. For example, my own Node.js images are built this way: docker buildx build --push \ -t <localrepo>/<project>:<tag> \ --platform=linux/arm64,linux/amd64 \ --file ./apps/<project>/Dockerfile . This produces both the AMD64 and ARM64/v8 variants automatically. Also, as a side note, it may be best to avoid using Alpine as the base image for the ARM64 build, since musl-based builds often cause compatibility issues and unnecessary headaches. A glibc-based base image (e.g., Debian or Ubuntu) tends to work far more reliably on ARM64, especially for Node.js applications. @toggledbits - tagging you in case you missed this. Thanks, mgvra

Script action and custom timers
therealdbT
Sorry to write here without trying, but I’m flying today. Am I correct if i say that script action with alarm() makes it possible to execute a reaction in a given interval, lets say 15 seconds or 3.5 minutes? That sounds amazing, since I’ve used weird tricks, including a custom controller, just to do this.

There is an alternative to homebridge-mqttthing
CrilleC
Just throwing out a general hint to the people running Homebridge and MQTT. Homebridge MQTT-Thing hasn't been updated in almost 2 years and it falls behind on compatibility with the development of Homebridge. I was looking for a replacement and found Homebridge Easy MQTT and I think it's a good replacement for MQTT-Thing. I particularly find Easy MQTT Value tranformers easier to to understand and use compared to MQTT-Thing Apply function. It took a while to migrate everything but I'm pleased and can recommend.

Reactor Version 25310 : Office Light control via rule in reactor no longer working since last update.
P
Hello, I currently have an office light (connected via a Leviton Zwave Dimmer switch) controlled from a Gen5 Aeotech Zwave switch installed on my Synology 720+ NAS. I run HA(2025.11.10) in a virtual machine from my NAS and Reactor on the container manager of the same NAS. Prior to updating to 25304 the rule I had set to turn the light on to a specific dimming value worked correctly. Now the rule appears to follow the decision tree, however the reaction does not trigger setting the dimming or turning on the office light? Strangely I can still turn the light on and off as well as dim it directly from HASS..? I have tried using the ''try this action'' button in the rules reaction setting and it will not control the light and does not throw an error flagÉ Please help, P.S Reactor has been rock steady for me over the last few years and I'm a big fan of this solution.

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).

    T Tarkus

    @toggledbits said in Feature request on reactions side.:

    whereas buttonCodes[ . ] and buttonCodes["x"] simply make no sense.

    These are actually OK if buttonCodes is an object, not an array. You can use the square-bracket notation same as dot member access, so buttonCodes[ "x" ] (note the quotes so it's a string) is the same as buttonCodes.x. Using the square bracket notation lets you use a variable for the member name. You don't need a second array, you just need to structure buttonCodes correctly...
    buttonCodes = { '0': 'codes for 0', '1': 'codes for 1', '.': 'codes for dot' }
    key_to_send = "." # or whatever/however you get the key
    send_data = buttonCodes[ key_to_send ]

    I ended up using this method and it works great!

    Thanks for all the help.

    Secondly, your definition of buttonCodes itself shows just a long comma-separated list, which cannot work as is. To make it an array, it must start with [ and end with ].

    Yeah i had the brackets but it did not work so the absence of of them is just me trying different things and not knowing what I am doing. LOL

    The X's are just left over remnants of the lua process I was using. It was just padding and acted a indicator that the channel was at a end and stop the process. So channel 7.1 would come over as 7.1xx. I set 5 characters to accommodate a 5 digit channel i.e. 135.1 I will take a look at your suggestions.

    @librasun Sure I currently have lua that has multiple "if" conditions that is run on the reaction side. Consider these "if" conditions in the lua the secondary conditions.

    Usage senario:

    Say you have 3 separate expression / variables with varying values of 0-9 lets call them.

    Variable_1
    Variable_2
    Variable_3

    On the reaction side

    If variable_1 = 2

    Send TV IR code for digit 1

    If variable_1 = 2

    Send TV IR code for digit 2

    etc, etc

    delay 1 second

    If variable_2 = 1

    Send TV IR code for digit 1

    If variable_2 = 2

    Send TV IR code for digit 2

    etc, etc

    delay 1 second

    If variable_3 = 1

    Send TV IR code for digit 1

    It does not have to be on the Vera side. I can get the 3 digit variable into a MSR expression I just don't fully understand how to parse the characters into 3 separate entities for MSR to evaluate in a 3 seperare rules.i do follow what you suggested but just not sure how to implement it in MSR These are for TV channel.IR codes. I am using a lua routine on the Vera side for this and it often causes luup restarts. And I am just looking for a different approach.

  • Parsing an expression
    T Tarkus

    So this would have to be lua on the vera side that populates the extract variable which I can then define as an expression in MSR? I am using the multi-string plugin which gets populated with a 3 digit string on multistrings variable1 and I want to perform 3 different reactions based on the varying values of characters 1 2 and 3. One reaction for each character. It sounds like I would need 3 variables extract1, extract2 and extract3.

    Multi-System Reactor

  • Parsing an expression
    T Tarkus

    If an expression value has a value of 789 can you isolate a character in the expression? i.e. If character 2 = 8 then perform a reaction. If not is this even possible to implement if I put in a feature request?
