Hi,

Today I install your code to ESP8266 and connect to the boiler. There is any option to send current room temperature to the boiler via OpenTherm standard? On DeDietrich screen I have message that CIRCA controlled via Opentherm module but I have "-----" in place where should be current room temperature.

THX for your work!

Hi did you add your external temperature into the code?

macgyverek commented 3 years ago

Yes, I added. Is working on Home Assistant. But this temperature is not sending back to DeDietrich Boiler.

That seems odd but when I tested it worked for me. Only the PID version is a bit harder as I don't know what it all means and do. I have an ideal logic+ so I can't help much as boilers implement open therm differently. try different sensors can u see any reading on the actual temperature sensor.

Hi @macgyverek,

The current room temperature can be sent to the boiler, but several code changes are necessary to achieve this.

I have made these changes in this new branch, and you can see them in the branch comparison

I haven't tested them connected to the boiler but they should work :-)

This version not working. Many connection and disconnection from Home Assistant. MQTT not see data. On logs is: connecting to Home Assistant and Dissconnecting from Assistant. Hmmm.
