I'd suggest the following formula if for any reason the valve goes below the minimal pos:
{{%elif value_json.thermostats.0.pos<=min_pos}%}}idle

Is this the same minimal_valve_position parameter, that was already supported ? I mean this update will not introduce the Minimal Valve Postition to Report Open parameter?

Honestly, I don't like this change, we have to add an additional parameter, which is actually available but in a different payload. This is just stupid. That's why I opened a feature request to add valve_min_percent/valve_min_report to the payload from the info topic. We'll see what the Shelly team's response will be.

I totally understand you and if it is not a critical issue, you can cancel my request. minimal_valve_position itself was already mapped in your code and this is why I thought about stepping further. But I didn't see the issues coming from different payloads.

No response from Shelly team so I will merge this change.
