[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.

Reactor (Multi-System/Multi-Hub) Announcements
toggledbitsT
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.

Links to MSR from HA

I am using Home Assistant a lot recently. On a dashboard showing the devices, I would like to show a link to the MSR rule that controls the devices. Is there a way to link directly into MSR?

Wiring Samotech SM308-S into light fitting
F
Hi Smart Home Community. I have used a Sonos inline WiFi switch to make one of my light fittings smart, but it requires a hard reset for WiFi changes, plus it isn't zigbee compatible, which means I can't use the Hue app to control it with the rest of the lights. To that end I bought a Samotech SM308-S as it is recommended as the better than the Sonos equivalent. I am however not exactly sure how to wire it in. The manual is available here Can anyone help me by clarifying which ports I need to use, and whether I should be using the live or switched live line for live etc. I will be keeping using standard switches for a while, although hope to upgrade to tap dials once I have all the fittings upgraded. Thanks

  • Have reactor shut off a light with no motion unless I turned it on manually
    S sethlampman

    So I have a strange one here and I don't know if there is a way to do this or not. I have blue iris triggering a vera virtual switch when AI detects motion on my front porch. Reactor then triggers the light, this works perfect. I want to shut the light off when there is no motion, this also works perfect. What I am having am issue with is when someone turns on the light manually I don't want it to turn off after motion is detected. Example: we are expecting a pizza so we turn on the porch light. 5 min later amazon delivers a package, trips motion. 10 min later Reactor is going to turn off the light. If I manually turn on the light before motion is detected I do not want reactor to turn it off. For the life of me I cannot figure the logic out. Does anyone have any ideas?

    @toggledbits thanks that works great (the workaround). One slight typo though, you have script instead of scene in the graphic.

  • Help with controlling Hue lights through Home Assistant & Reactor
    S sethlampman

    Ok so I am trying to do something that I think is simple but apparently not LOL. I want to turn a hue light on yellow when a condition is met. Basically we have really high humidity here in the evenings. When the garage door is open and the humidity is over 60% then I want my hue garage door light to be yellow. If below 60% then I want it to be white. This is simple enough.

    Here is my problem. I cannot find anyway to control the hue color directly from Reactor. There is an x_hass_light.turn_on function but it doesn't do anything when you define a color.

    No problem, I will create a scene in Home Assistant and set my color there, then call that scene from Reactor. (Not elegant, but will work). Created a scene, works great and sets my color the way I want it.

    I go back into Reactor -> Entity Action -> Garage Door Yellow (scene name) and then there is this annoying little box that requires a selection when there is no selection available. There is nothing for me to select and I cannot save because it is expecting input.
    784eafef-6c29-4b78-816c-006a81e41564-image.png

    Can anyone give me some advice on how to accomplish what I am trying to do? I would like a way to do this 100% in reactor (set the light to a color of my choosing) but I am OK with a workaround by using HA scenes. I just need it to work without asking me for a section input that isnt there.

    My next step is to create a virtual switch in Vera, then create a an automation in HA that will trigger my color. Then use Reactor to trigger the virtual switch... I think that is kludge and will likely confuse me months later when I go to edit a rule and forget this workflow...

  • Issue with yellow triangles next to rules
    S sethlampman

    Here is the crazy thing. The sensor values were stale, I changed a value in the rule and then saved it. Now there isn't an exclamation point and the sensor value is updating as well. Almost like it was stuck after the upgrade?

  • Issue with yellow triangles next to rules
    S sethlampman

    So I upgraded to the latest docker version of Reactor. Now I notice that some of my rules have a yellow triangle before them. I hovered over it but I don't see any explanation as to why. I searched the docs and the forum but I can't figure out why it is showing. If I go into the rule I don't see any errors. Any ideas?

  • Expressions in MQTT Payload?
    S sethlampman

    I'm trying to send a video overlay to BlueIris. BI is receving my MQTT Message and it is writing it to a Macro but it doesnt appear that I can use expressions in MQTT Payloads with Reactor?

    Output from BlueIris (no expression data):

    I figured a workaround by using HTTP GET but I just wondered if I am doing something wrong with getting expression variables to work with MQTT.

    This works with BlueIris:

    For the life of me I cannot figure this out.
    when I run the du -hs command (from the host) for the mapped volume I get 25M
    (/home/seth/ReactorConfig maps to /var/reactor)

    Inside the container I ran du -hs for each of the folders that the ui is complaining about
    /opt/reactor = 71.2M
    /var/reactor/storage = 2.9M
    /var/reactor/logs = 17.6M

    If I run df on the docker container I get this. Disk space is not critical

  • Home Assistant Script, Reaction requires seclection that isnt there
    S sethlampman

    Thanks! I got the scripts working now so I have a way, although ugly as it is.. I did setup MQTT in reactor but the documentation has me very confused. I don't know how to create a template or anything like that. I basically just want to be able to publish a value that I specify to aqualinkd/Filter_Pump/RPM/set. Is there an easy way to make that work?

  • Home Assistant Script, Reaction requires seclection that isnt there
    S sethlampman

    I'm trying to create some automation so I can control my pool variable speed pump from reactor rather than iAqualink (which sucks). My controller is MQTT enabled so I created several scripts for my desired speeds. (I know reactor has MQTT ability but honestly I read the docs and could not make much sense of it and since I already have it set up in Home Assistant, I figured I would just leverage that instead)

    So I created all of my scripts and tested them, they worked perfectly. The I created a rule in reactor and set running the script as the action. The problem is that reactor is telling me that I have to make a selection. I try to click the dropdown and there is nothing to select. I cant save the rule, the only option is to exit.

    9e0a3147-5058-4893-9860-2f0d759dfe3c-image.png

    Here is my script in Home Assistant. Any advice on how to get this to work? If I am looking at this the wrong way I am open to suggestions (I would rather be able to call a specific action and specify a speed value but I cannot figure out how to do that). Thanks in advance.
