Hi folks. Once again I’m delving into writing / tweaking smartapps and I’m running into the same problems I always seem to. Specifically subscribing to events, using attributes, etc. I have worked out a few issues, but am having real problems getting certain attributes from my thermostat. Any help would be appreciated.
I need to retrieve and make decisions based upon the current heating and cooling setpoints. But here’s the log data I’m getting:
ThermostatCoolPoint = null, ThermostatSetpoint = null, ThermostatHeatPoint = null.
I have also never figured out how one posts code in a sane format, but that’s a different issue 
The code is extremely simple. Why am getting null responses???
