Hi. I have a problem with a Netatmo thermostat. I had it integrated into HA with the Home kit integration. One day its battery went flat and when I replaced it it didn't connect to HA anymore. It works Ok with the Netatmo app, but not with the Home kit integration in HA. I tried removing it from the app ( which supposedly put the thermostat in "pairing mode" but it is not visible from the homekit integration. Any idea on how to set it again into pairing mode?
