It's the Bedroom Thermostat.
The action triggered at 6:15 this morning - but didn't change the thermostat.
I manually changed it at 6:17 using Home App on my phone (HomeBridge)
Here are the Events...
Looks like the rule sent the command, but the thermostat didn't respond for whatever reason. Enabling all logging for the rule will show you more details, including what it's actually trying to set it to (something you can't see in the event/command history) and is generally a good step for app troubleshooting.
Very strange... Ok.. while it's in debug mode still.. Can you set it manually like you did before? I want to see if the command being sent is different somehow..
