Thermostat control via smartthings

All of a sudden I cannot control our thermostats through SmartThings (or Alexa).

Via SmartThings, I receive the error message, “A network or server error occurred. Try again later.”

I receive this error on multiple IOS devices trying to manage multiple thermostats.

I reset the SmartThings hub but no joy. Any suggestions?

I’m sure that’s very frustrating. :disappointed_relieved:

We need to ask a few questions first:

Brand and model of the thermostats?

What country are you in?

Do you have a SmartThings/Aeotec hub, and if so, which model?

I have that problem too. But only with my virtual thermostats.

Is it working now? There was an outage earlier

I am in the US.

One thing I find interesting is that I can control the STATE of the thermostat (off, heat, a/c…) but not the temp.

I’d guess I’ve had this hub close to 4 years, since Lowe’s discontinued Iris. It’s always worked great until recently.
