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?

[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.

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.

Gradually turn on lights.

I have several lights that I would like to turn on very gradually over 15 or 20 seconds. from 0 to .25 in .01 increments. I have tried a few things that came nowhere near working, so here I am.

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.

Can't customize home page
G
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
Tom_DT
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

  • Installed latest MSR container and host time is wrong
    M maddios

    Ah, yes that was exactly it, TZ env variable was missing, no idea why it went away after portainer recreated the container.

    Yeah, I'm running on linux (ubuntu 18.04lts) but I use portainer to manage my containers.

    Thanks for the tip for resolving the error, I'll poke around and see if i can find one that got corrupted. I don't think I've ever had this disk ever go full before but this server has had a couple annoying crashes over the past year, maybe one of them corrupted something in reactor.

  • Installed latest MSR container and host time is wrong
    M maddios

    Hi, I've been using msr for a while now and haven't had timezone issues until today when I updated to latest docker image (latest-22080-ae7212f)

    both docker date command and my local date command show the same time, same timezone, but for some reason MSR shows the host time as 2 hours in the past as a result all my timed rules run 2 hours late.

    my locale is set correctly in the host machine and is bound into the container as well.

    One possible hint I get is maybe this from the container startup log, but other than timezone stuff everything else seems to be working fine and all my settings loaded up just fine.

  • Passing expression variables between rules
    M maddios

    Not sure if anyone's suggested this, but it would be great if the expressions could be grouped. Like for me I have tons of variables for my thermostats, tracking all sorts of house parameters which all of the thermostats share. Would be great to have an object to contain them all so I don't have all of the expressions mixed up. something like thermostat.first_floor.heat_current_setpoint would be really cool.

    Thanks, that worked for my needs. So far I like this new system, seems much snappier.

  • Passing expression variables between rules
    M maddios

    Let me know if this is correct, I'm using a reaction in a rule to set the global average expression to my local ${{average}}. Is that the correct way?

  • Passing expression variables between rules
    M maddios

    Ah, so I can't copy over some of my vera reactor logic.

    How do I reference global variables within rules? do they just work like local variables? or is there some sort of global scope object I have to use?

    I'm guessing I can pass data between rules by using a global expression

    Also, how do you recommend structuring one of your old guides where a bathroom humidity sensor samples humidity into a dictionary then calculates averages and such. then another vera reactor was consuming that average and checking if it's above/below current humidity and turning a fan on off?

    Thanks

  • Passing expression variables between rules
    M maddios

    I've found I can see variables from other rule sets within the rules themselves, via the "Variable Value" condition type. Just need to figure out now how to get to this in an expression.

    Multi-System Reactor

  • Passing expression variables between rules
    M maddios

    Is there a way to get a variable from a rule into an expression of some other rule?

    Just like what Vera Reactor did with the Export button then allowing you to reference that variable in another rule set. I'm guessing there's a function like there was in vera getstate()? Thanks

    Hopefully my question is clear, it's late 🙂
