Hey @bravenel , could you have a quick look at this? My rule for activating thermostat setpoints used to run great but somewhere between 116 and 119 it started throwing an error, I think just on 119, but can't be certain of that.
The Rule is pretty basic, when I arrive home it should activate the scheduled setpoints on two of my devices per the thermostat scheduler.
Try editing both of the actions that set Thermostat Scheduler; just hit Done Editing. I think that will fix it. If not, then remove the actions and recreate them.
I don't quite understand why the "editing and hitting Done" works, but it did for me as well. Hopefully, this is now a known glitch and will be addressed in future release.
