Hi @jotto,
Did you update the device type or the smartapp recently without doing save & publish?
Your environment may be in a bad transition state.
Could you make sure that you have the latest version of the device type (v2.0.13), my Ecobee init (v.1.9.4) and, if you have ecobee3 remote sensors, the ecobee3RemoteSensorsInit smartapp (v1.1.3), and save & publish:
If you still have issues, please PM your detailed log (before this exception)…
I just did a “copy and paste” of my device type code, and it’s working fine in my ST environment.
P.S. Like I posted on another thread, here is my answer about temps not updating:
Since ST did your cloud optimization (and introduce rate limiting), many devices now need to be polled in order to get the latest values.
A good example of this is the weather station, see this thread below for more info. As you can see in the last posts of this thread, even stock ST devices now need to be polled in order to get the latest values, and it’s not as reliable as it used to be.
In any case, my code will not generate sendEvent commands if the temp values have not changed, so if your indoor temperature is stable, you may not see any temp updates for many hours.
Regards.
