I got one of these today, it has humidity on it too but stays at 16% all the time. Wonder if it's disabled?OK, I'll say it first, you generally get what you paid for.
Yes - I got what I paid for - a temperature sensor. Not sure why you think they're any worse than any other temperature sensor you can get for these types of system. Anyway, I just set my bridge decoder to ignore the humidity reading for the temperature only ID's.
