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.
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?
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

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.
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.
@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.
I'm running MSR build 25139 on Docker, using MQTT controller 24293, and everything working as expected. But if I try to upgrade to MQTTController build 25139, I'm getting the following errors on MSR UI:

I realize my MQTT configuration might be a bit unorthodox, but could there still be something unintentional in the latest MQTTController build? If needed, I can provide detailed logs.
Since today is my birthday - and I still pretend to be unconventional - I'm giving away a present to this wonderful community and I'm releasing my first OpenSprinkler controller for MSR. It was real fun to code it - and while it's still WIP, it seems to work OK for me. It's polling-based at the moment, but I'll add support for updates via MQTT very soon (it's already partially coded).
Get it at (install is similar to MQTTController and such):
https://github.com/dbochicchio/reactor-opensprinkler
Feel free to try it. It's beta software, but it's stable. I'll update it weekly until all the tasks from my todo list are empty.
Since I've learnt a lot from this controller, I'll explore new controllers soon.
Good day all,
I'm in the process of trying to shut down my 10 year old Linux home server that served many purposes, but primarily it's what I used for my NAS/Plex Media server. I migrated the NAS aspect of the server in November of last year to a true NAS solution (Ubiquti UNAS Pro), which is rack mount and much more efficient than my old tower, which it's only side benefit was heating my home office during the winter. Unfortunately it also means heating my home office during the summer, which were about to be in full swing.
I have two things running on this 10 year old server at this point. MSR and pi-hole. I'm running Plex Media Server on Fedora Workstation in Podman on mini PC, which is much more energy efficient than my old tower. My next step is to migrate MSR. I know there are images of MSR out there, and creating it is well documented. I'm going to be using Podman instead of Docker for various reasons, but they work very similar. What I don't know, is what I need to do to migrate my existing Bare Metal installation over to a container.
Has anyone done this? Any advice?
Passing expression variables between rules
-
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
-
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.
@maddios said in Passing expression variables between rules:
I've found I can see variables from other rule sets within the rules themselves
That's a bug. Rule-based expressions are only in scope within the rule that defines them (just as local variables in almost any language are available in the scope that defines them). For the same reason, you cannot refer to variables in other rules from an expression.
-
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

You refer to global variables the same way you refer to local ones, as you would in most computer languages.

You refer to global variables the same way you refer to local ones, as you would in most computer languages. You simply refer to it by name. If the name is not in local scope, the parent scope (which is the global scope in Reactor) will be searched for the name.

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.
