My InComfort app workt for 3month, without any issues .
But i had to power down the complete supply to my home, and afterwards

Error during setup of component incomfort
Traceback (most recent call last):
File “/usr/src/homeassistant/homeassistant/setup.py”, line 404, in _async_setup_component
result = await task
^^^^^^^^^^

raise InvalidHeaterList
incomfortclient.InvalidHeaterList: There is no valid Heater in the heaterlist (check the binding between the gateway and the heater)

it was working before reboot, but now not anymore
I reboot and restart HA several times but still the same error

in config.jaml i have only this:


# Example configuration.yaml entry, newer firmware with user credentials
incomfort:
  host: xxx.xxx.xxx.75 
  username: !secret ketel_username
  password: !secret ketel_password

IP is not changed
also with the username and password i can login to gatway of intergas

what is wrong ???

After waiting for at least 6h i did a reboot of HA again
And yes it was running again. It look like it needs more then 2 hours to get a binding
