[SOLVED] String update through rules

I’m using (since a while now) a rule to control our HVAC.
In this rule, i’m using House_Mode to check what must done (home, away, holiday…).
When I now set these values through the sitemap, it works great.

I now just introduce an automaticlly update through a rule (triggerd by a switch).
This works (for lights, audio…), and I see in my logs that the status is updated.
But my HVAC rule doesn’t notice the changes.
Any idea what I’m doing wrong?


String  Heating_Mode                    "Globale HVAC Mode [%s]"


Selection item=Heating_Mode label="Modus []" icon="temperature" mappings=[

Part of HVAC.rule (working with sitemap)

    else if (Heating_Mode.state.toString == "Werk") {

The rule that update the Heating_Mode, but the rule above doesn’t take it into account?

      Item GebouwVerlaten received update

Hi, @brononius, instead of posting a state update to your Heating_Mode item, use sendCommand():


Also, use the sendCommand() method rather than the global function in the other lines, assuming Sonos_Controller and TeRuMan are items.

I had this one before, but was the same result.
Maybe I made a typo then, will try it again…

Same result. But maybe a stranger finding?
‘UIT’ and ‘work’ looks like working. But ‘Afwezig’ not?

A bit more details about the rule:

        else if (Heating_Mode.state.toString == "Werk") {

Hmmm, very strange.
The rule is taken into account after about 6 hours?
Nothing changes on ‘human’ side.

No idea why, so guess something else will cause the error… :blush:

I run in parallel a test script with logs, and seems that the error is somewhere else.
Nothing to do with the update from a rule… :blush:
