self-regulation and temp display on TRV, does VTherm adjust the offset/calibration variable?

[maia]

It's been months since I last spent time with TRVs, but something has been nagging me the last winter: My Eve Thermo TRVs (Homekit) did not adjust the displayed target temperature based on the self-regulation. This led to lots of confusion as people turned down the TRV when they noticed that it was set to 25°C, even though that was just VTherm self-regulating.

I'm now considering the purchase of new TRVs with Zigbee protocol. Can VTherm now properly adjust the display on the device itself by changing the offset? For example the SONOFF TRVZB and also the AVATTO TR168 expose the variable local_temperature_calibration (see: https://www.zigbee2mqtt.io/devices/TRVZB.html and https://www.zigbee2mqtt.io/devices/ME168.html ) which defines the "Offset to add/subtract to the local temperature". Will VTherm use this variable in its self-regulation feature, which should allow keeping the target temperature displayed on the TRV synced with the target temperature in HA? Thanks!

Hello, it is not planed today but this can be an interesting update. Do you have an updatable entity named "local_temperature_calibration" ?

what's the valve status? If it's above 0% it will show as heating.

It was indeed at 15%, but why is it open when the temperature is above the setpoint?
I’d also like the option to skip defining the valve entities and simply use the basic on/off climate mode.
It feels like these two features -the offset and the valve opening/closing method- shouldn’t be really linked.

They're not, you can probably leave the valve entities unfilled.

If you have auto regulation on it may open the valve to prevent undershoot. Check in on the trvzb issue/topic (Y)

The Valve Opening one seems to be mandatory.

It’s likely because that options menu only becomes available when "Auto-regulation" is set to "Direct control of Valve." However, as mentioned earlier, that’s not something I actually want to use.
