rule does not trigger with duration defined

---

Hi,

after trying pimatic 0.8 one year ago I’ve now setup 0.9 with success to control my house heating, mainly my floor heating. 0.9 and the visual rule editor is very good and allowed my to implement my automation very fast. Good work pimatic-Team.

To do that, I’m switching the valves for each room with an actuator switched on/off by a remote controlled power plug. homeduino is controling this. Every rule works fine unless I’m using a duration statement.

working example:
"id": "fb-flur-on", "name": "FB-Flur-on", "rule": "when S2T of temperaturflur is less than 20 then turn Schalter 2.A on", "active": true, "logging": true

This is not working:
"id": "fb-flur-on", "name": "FB-Flur-on", "rule": "when S2T of temperaturflur is less than 20 for 20 minutes then turn Schalter 2.A on", "active": true, "logging": true

Is there something wrong with my rule or is this a bug?
The duration statement is very helpful for heating control to avoid fast switching.

Also I’m wondering why “Log messages” is empty, no line visible. The daemon-log is ok.

Regards
Stefan

Is there a space between 20 and minutes?
In my rules I have no space and they’re working.

Are you sure, that the temperature is lower than 20 degrees for the whole 20 minutes?

Yes, that’s what the rule editor is doing. And this was working with my first rule (used for testing). But now with several rules (I have 5 valves to control) it is not reliable.

Yes.

For me it’s working too.

Yes.

It has too be below 20 the whole time! One short pike from 19.99 to 20 and back, and the 20 minutes are starting again.

An other thing is, that time-rules are working bad for heating.
Use hysteresis. Something like "on at 19.8“ and “off at 20”. Or try the mythermostat-plugin. As i remember it can do “Bang-Bang” for floorheaters, like yours.

Thanks for your feedbacks.

For the moment I will keep some duration settings and monitor them for a few days. During last night, everything worked fine. I’m still in “tuning” mode for my whole installation.

I will also try your suggestions for other plugins …
