  4. Issue with a Trigger Rule using "changes from blank=any value to blank=any value"
Gradually turn on lights.
Tom_DT
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.

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?

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?

Errors after updating to MQTTController build 25139
tunnusT
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: An Entity Attribute condition in "Lay-Z-Spa auto heating off" (Terrace) failed because the referenced entity "Lay-Z-Spa States" (mqtt>layzspa_states) does not have attribute value_sensor.god Last 11:20:37 An Entity Attribute condition in "Lay-Z-Spa auto heating off" (Terrace) failed because the referenced entity "Lay-Z-Spa States" (mqtt>layzspa_states) does not have attribute temperature_sensor.green Last 11:20:37 An Entity Attribute condition in "Lay-Z-Spa filter pump auto off" (Terrace) failed because the referenced entity "Lay-Z-Spa States" (mqtt>layzspa_states) does not have attribute temperature_sensor.red Last 11:20:37 An Entity Attribute condition in "Lay-Z-Spa filter pump auto run" (Terrace) failed because the referenced entity "Lay-Z-Spa States" (mqtt>layzspa_states) does not have attribute value_sensor.pump Last 11:20:37 An Entity Attribute condition in "Lay-Z-Spa watchdog" (Terrace) failed because the referenced entity "Lay-Z-Spa States" (mqtt>layzspa_states) does not have attribute value_sensor.status Last 11:20:37 My MQTT configuration (local_mqtt_devices.yaml) for the related entity is: layzspa_message: type: ValueSensor capabilities: ["temperature_sensor", "value_sensor", "power_sensor"] primary_attribute: power_sensor.value events: "layzspa/message": "power_sensor.value": json_payload: true if_expr: '! isnull( payload?.PWR )' expr: "float(payload.PWR)" "value_sensor.air": json_payload: true if_expr: '! isnull( payload?.AIR )' expr: "float(payload.AIR)" "value_sensor.pump": json_payload: true if_expr: '! isnull( payload?.FLT )' expr: "float(payload.FLT)" "value_sensor.god": json_payload: true if_expr: '! isnull( payload?.GOD )' expr: "float(payload.GOD)" "value_sensor.lock": json_payload: true if_expr: '! isnull( payload?.LCK )' expr: "float(payload.LCK)" "value_sensor.unit": json_payload: true if_expr: '! isnull( payload?.UNT )' expr: "float(payload.UNT)" "value_sensor.error": json_payload: true if_expr: '! isnull( payload?.ERR )' expr: "float(payload.ERR)" "temperature_sensor.green": json_payload: true if_expr: '! isnull( payload?.GRN )' expr: "float(payload.GRN)" "temperature_sensor.red": json_payload: true if_expr: '! isnull( payload?.RED )' expr: "float(payload.RED)" "temperature_sensor.target": json_payload: true if_expr: '! isnull( payload?.TGT )' expr: "float(payload.TGT)" "temperature_sensor.value": json_payload: true if_expr: '! isnull( payload?.TMP )' expr: "float(payload.TMP)" "temperature_sensor.virtual": json_payload: true if_expr: '! isnull( payload?.VTM )' expr: "round(float(payload.VTM), 1)" "temperature_sensor.ambient": json_payload: true if_expr: '! isnull( payload?.AMB )' expr: "float(payload.AMB)" "layzspa/Status": "value_sensor.status": if_expr: '! isnull( payload )' expr: "payload" "layzspa/button": "value_sensor.button": if_expr: '! isnull( payload )' expr: "payload" and in reactor.yaml I have: "layzspa_states": name: "Lay-Z-Spa States" friendly_name: 'Lay-Z-Spa States' include: layzspa_message I realize my MQTT configuration might be a bit unorthodox, but could there still be something unintentional in the latest MQTTController build?

🎉 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?

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.

Organizing/ structuring rule sets and rules
R
Hi guys, Just wondering how you guys organize your rule sets and rules. I wish I had an extra layer to have some more granularity, but my feature request was not popular. Maybe there are better ways to organize my rule sets. I use the rule sets now primarily for rooms. So a rule set per room. But maybe grouping by functionality works better. Any examples/ suggestions would be appreciated.

    Hello Patrick,

    Hoping this is the right place to ask the following.

    Not sure why, but since I upgraded Reactor to 22293 from 22258 I have a rule that no longer works as expected. I keep a log of all changes/updates/upgrades/etc. I make in my environment and cannot find any recent changes that could have caused this. Maybe it was pure luck that it worked until recently? Hopefully you can steer me in the right direction. Thanks

    I am running Reactor (22293) / HA (2022.10.5) /InfluxDB (2.4.0) / Grafana (9.1.5) inside Docker on a Synology NAS (DSM 7.1.1-42962 Update 1).

    The rule's trigger is designed to update a Home Assistant Helper entity (input_number) value that is used in Grafana to display Humidity Target in my house.

    I set the rule as follow:

    When the Variable Value (HumidityTarget) changes from blank=any value to blank=any value, set the Home Assistant Helper entity value (h_Humidity Target) to Variable Value (HumidityTarget).

    If I manually change the Global Expression Variable Value (HumidityTarget) it works but using the changes from blank=any value to blank=any value does not seem to work anymore.

    Set h_Humidity Target.jpg

          I think it has to do with how the global expression is evaluated, see the excerpt from the docs "A global variable is evaluated when a rule that refers to the global variable in its own (rule-based) expressions or conditions is evaluated, or when a reaction is run that contains actions with substitutions referring to the global variable.". If that is the case try moving this variable to a local expression and see if that works.

            To answer Patrick question. If I manually change the Global Expression Variable Value (HumidityTarget) to equal 45 (instead of 40), it will trickle up to HA / Influxdb / Grafana.

            This value could be stale for a long time and don't want to manually update/refresh this value. That is why I used "changes from blank=any value to blank=any value".

            I'll try @Pabla suggestion.

              OK, wait... if you change the variable manually, and it trickles up to HA/Influxdb/Grafana, that means the changes is working, because that true pulse causes the Set reaction to run, which is what pushes the value to your input_number entity on Hass.

              How do you know it's not working when you think it's not? What is the observed behavior?

                Observed behaviour: On my graph, HumitidyTarget stop being displayed since Oct 21. The date of the upgrade. I waited until the next day, to see if it would show up, and the next day, and then today, still no visual.

                  OK. And is the value actually changing from one value to another during that time, or is it static (same value) for that time?

                    At moment, the value is pretty much static since the temperature has not dropped below -6 Celcius.

                      OK. changes means just that. If the value doesn't change, it isn't going to trigger anything. When you make a condition for changes from any to any, that means the value changes from any value to any other value. But if the value never changes, that condition doesn't go true, your Set reaction does not run, etc.

                      If you want to make sure your value is pushed out to HA on some interval, you need to set the logic mode to OR and add an Interval condition with an interval you are happy with, let's say hourly. The two conditions together working in an OR group will send the target to HA every hour, and any time the value (actually) changes.

                      Edit: There's nothing new here. It has always worked this way.

                        @toggledbits Wouldn't switching the expression to a local expression fix this issue to? Since a local expression is evaluated differently?

                          No. The issue is that the value is not changing for a long period of time, so regardless of if it's local or global, the changes will not trigger on its own, and the Set reaction will thus not be run. This creates a gap in Influxdb's data that may be larger than the period he's asking to show in the graphs in Grafana, so nothing is displayed.

                          The other way to address this is to use the last aggregator in the Influxdb query in Grafana, so that the last value stored in the database is carried forward through the graph. This is harder for people to understand and implement (because you need to be fluent in the query language), but it's actually the "right" way to do it. Having data pushed on an interval can wastefully fill the database with identical values.
