Timeout when calibrating boiler with opentherm and mqtt

[utarestev]

Hi

I am new to this integration. I am trying to configure it with an opentherm gateway from No-do. I am not an expert neiter home assistant nor opentherm. Here is my guess

I am trying to configure it with MQTT but I am receiving a timeout error waiting the boiler. The problem is SAT integration has not been able to receive boiler changes but the boiler does receive them. Boiler starts and stops during de configuration and calibration process.

Looking at the code when adding the integration, it seems to use SatMqttCoordinator to handle boiler changes. This class has a async_added_to_hass method which wait por mqtt and create the handlers for listening the events.
The problem is that method is never called.

SatMqttCoordinator is instantiated manualy in SatDataUpdateCoordinatorFactory and not by home assistant, so async_added_to_hass is not called at this point.

Later, when integration is already added, that method (async_added_to_hass ) is called by hass and SAT is able to capture mqtt boiler events.

Thank you

Since he automatic calibration is not working, please try the manual method #36 (comment)

I was only trying to explain why I think (althougt I am not sure) automatic calibration does not work (at least on opentherm and mqtt) and why SAT is not receiving mqtt values from the boiler.

For calibration, I've configured it by serial, waited for calibration to finish and copied the value.

In any case, thank you for your amazing work
