Can anyone explain these annoying outlier points from my zwave thermostat? This is from a honeywell thermostat, but before this I had a trane that suffered from the same problem. It happens with current temperature and humidity. It's not like its terrible, it doesn't mess with my automatons or anything, but when I want to look into my heating history it really screws with the scale
-128 sounds like an error for sure. move your hub closer could help. If you're sure it's not a distance/signal issue it's the hub itself.
