Apparently Smartthings is having some issue where it is sending too many commands to Honeywell Home’s servers and flagging them as DOS’s. This caused Honeywell to lock anyones account that is connected to smarttings.
I don’t think my Honeywell account has been locked and it’s connected to SmartThings. I’ve had trouble in the recent past with SmartThings reporting my Thermostat s offline but they seem to work now.
