I migrated from domoticz all my RFXCOM RFX devices to HA.
All switches are well detected and working.
All the thermometers Cresta TFA give no temperature, all the atriburtes are indicated as unkown (battery, temperature, humidity).
In domoticz all temperature sensors TFA were well working.
Is something missing in the configuration?
I find the solution. In the rfx configuration you must activate the option: hideki.
All TFA device are working well now.
