  4. [SOLVED] Rethinking HVAC moving from Reactor (Vera) to MSR
[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.

Errors after updating to MQTTController build 25139

I'm running MSR build 25139 on Docker, using MQTT controller 24293, and everything working as expected.

🎉 My very first MSR controller: OpenSprinkler
therealdbT
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.

Advice reqeusted to migrate MSR from Bare Metal to Container
T
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?

    Remember, it's entirely plausible to introduce an expressionless (empty) "Go" variable within any Rule, such that the Rule A "runs" (acts Enabled) with "Go" set to "1", and is barred from running (acting Disabled) with it set to "0".

    To make this setup work, simply have your other Rule B's Set Reaction do a [ Set Expression ] [ = ] [ 0 ] on Rule A's variable "Go", with a [ Set Expression ] [ = ] [ 1 ] in its Reset Reaction. Create a corresponding Trigger condition in Rule A that tests [ Expression Value ] [ == ] [ 1 ], and you should be good to go.

    Does that make sense? Hope it helps!

    NOTE: You can also use true / false values for Go and make your Rule A's Trigger condition check for [isTrue] instead.

      Before I do (let's save Expressions for very last...), please explain how MSR could "know" which version of the weather sensor you want enabled?? I'll go re-read your posts from the past 24 hours to see if I can ascertain same.

        For instance, I heard you say, "I cannot turn off the OWM ruleset (in MSR) when Ambient API is driving". Couldn't its governing Rule just have an extra Constraint condition like:

        [ Entity Attribute ] [ SiteSensor_156 ] [ x_vera_device.failed ] [ isTRUE ]
        

        so that it refrains from execution while Ambient is in good health?

          Fair enough on the explanation - I prob made that typical error of not providing the details that I "just know" in my head. 🙂

          Original Vera setup: two SiteSensors, one for Ambient API, one for OWM API. Ambient is hyper-local (my wx station) and is the daily driver. To save API calls against OWM, the SiteSensor there is set to disabled status normally.

          If Ambient API call returns zero results, the Master API ruleset sees the failure, changes OWM API SiteSensor to enabled. As the query results from Ambient are blank, it is left in enabled status - and there's only one set of data points going to the t-stats.

          Once Ambient API call returns regular results again, the Master API ruleset sees the actual data and changes OWM API SiteSensor to disabled again and life is, once again, good for all.

          Can you define for me "refrains from execution"... are you saying it would not send anything to the t-stats or query the API (or both)?

            From all I see (I just stopped short of saying it explicitly earlier), you're asking, "How can I temporarily stop MSR from sending API requests to OWM?" I don't see an immediate way to set that mechanism's sys_system.state= to false, although that was my initial thought.

            I think we'll have to ask @toggledbits to advise on best practices here.

              @librasun I poked at this a bit with what I thought you were getting at. The configuration now (which is a carry-over from Vera Reactor and could prob use some trimming) has the top three rulesets (shown earlier) use to arm the system, ie set the parameters for what qualifies as "I should heat now" or "I should cool now" - and then the five rulesets below are the actual action rules.

              For instance, if the system "qualifies" for (or is armed) for Cooling then only the two rulesets for Cooling are actionable. Same applies for Heating.

              Taking what you said earlier, I added a condition to each of the action rulesets as shown in this example:

              85aed027-5c32-4d64-a0b9-2168f1f7073b-image.png

              I was missing the reality of the action rulesets still running even though none of the qualifiers/armers were, well, armed. The action rulesets were using the last known datapoints stored in the armers - and that's where things were going amiss.

              By adding the extra condition to each action ruleset it seems to have quieted - this may be the solution (not pretty, but a solution.)

                @librasun The arming rules look like this:

                In my mind, all of these conditions were rolling down to the action rulesets - which is not true.

                      As I'm marking this as [SOLVED] I thought I'd update on how this all ended up playing out:

                      Creation of two API rulesets, one for Ambient, one for OWM, that dump their data into Global Expressions. At issue was how to disable OWM to prevent needless API calls - I ended up doing the maths and making adjustments that this isn't an issue any longer. As such, one API ruleset for each dumping to clearly labeled Global Expressions. Yes, they both call out to their respective APIs but the volume is low enough not to trigger either for overuse.

                      The only gotcha here is to make sure that you include in the rulesets for the secondary (OWM) a Trigger that checks for the primary API to be returning null so you don't have both flavors of rulesets competing for Honeywell's API (which is notoriously cranky) as you set the t-stats.
