Hi @sygys , In general, we sell hardware PCBs and provide some basic usage samples, the rest functionality is up to your implementation. The OT Library allows you to send...

Hi @jase31 , Do you mean target boiler setpoint? It calculates using PID algorithm based on the temperature difference between target and current room setpoint.

Hi @windmillBart , Did you choose the MQTT sensor option from the thermostat Web interface? (Menu -> Sensor -> MQTT sensor)

Hi @Mozzzy , We plan to add this option in the next version.

Hi @stefanhapper, you can modify the sketch. Remove the PID function and use the value from some MQTT topic to manually set the boiler setpoint.

We've moved to another web-server implementation, so this issue seems outdated . Also tested locally, % sign in username/password does not break the UI. Can you confirm?

@wichers, Ihor has updated his OpenTherm library, now it supports DHW, just FYI

@zenz there is 4.2 version already, it is fully compatible with 2.2 version, there are no breaking changes.
