Hello, Do you think is possible to send Room Temperature and Outside Temperature from HA to opentherm ? I'm running nodoshop's opentherm gateway in conjuction with your OTGateway and it supports ID24 and 27 from master device. Also MsgID 57 Max CH water Setpoint that i set in OTGateway it is not sent to boiler, i had to set it manualy. Thanks. otg

Hi, Yes, ID 23 and 24 can be sent. But why is this necessary? Screenshot_7

But the protocol does not allow sending outside temp, only reading.

ID57 must be sent: https://github.com/Laxilef/OTGateway/blob/ead8c64e925812ef27b3dc7517a04b07b2e89b5b/src/OpenThermTask.h#L216

Because i have a display that is getting data from otgw and currently doesn't show room temperature.

Laxilef commented 12 months ago

I think this can be added. P.S. What kind of display?

aurelmarius commented 12 months ago

It is a waveshare epaper 7.5 screen hooked up to esp32. If it is too hard to implement this, i will eventualy flash the screen with esphome and get sensor data from homeassistant.

No, it's not hard. But I need to think about where else this could be used.

It seems to me that it would be more correct to use esp for this display 🙄
