I am not sure what is happening but that error message seems to imply that you are trying to compare a string to an interger. That is not possible with arduino as it stands now.

You should get the 'value' of the string into interger form to compare the values.

@skywatch it's not me trying to compare, it happens in the mysensors library when receiving messages. It seems that mysensors is badly implemented in the home assistant, in domoticz it works very well
