Question about ESPHome OpenTherm #1

Open foxalex85 opened 1 year ago

foxalex85 commented 1 year ago

Hi, sorry if I write here, but I didn’t found another way.

I’ve tried your ESPHome OpenTherm, that was modified with async calls, but it seems not work. With the original repository by risciano I’ve successfully connected with the boiler, while with this version there are somethings problem.

Did you have these problems or in your test all worked?

Thanks

I can connect to my boiler(Viessmann), but my boiler seems not supporting opentherm well. Did you change the mock variable @line 15 in opentherm_component.h to false?

bool mock = true;

Yes, finally I was able to connect to the boiler. For my boiler not all commands are supported. For example: I cannot set the domestic hot water and I cannot retrieve the flow rate. The "Opentherm API is not ready" in the log I thing is normal, because the OpenTherm protocol seems to be a little bit slow.
