I have a flow that triggers an outdoor plug to start my heater in my car. I want the heater to start at 6 o’clock if the temperature outside is below -5 degrees Celsius and start at 7 o’clock if the temperature is below 0 degrees Celsius.  
The flow only seems to work if I set the trigger value to a positive value, fore example below 5 degrees.

When  
The time is 06:00  
And  
Logic → Temperature tag from my outdoor Sensative Comfort Strip is less than -5  
Then  
Turn on outdoor plug

Just tested it on the new web gui and the mobile app, and it both work just fine if i use -5 (negative 5) in the logic “is lower then” condition card, as the temperature currently is -6 now here.

I think the problem is the latest version 5 beta that has caused me problems with flows using the When the time is function. I think that the firmware has been automatically updated around 06:00.

As Alpha tester I’ve been running pretty much every RC up until v5 was live yesterday, so that would mean it killed your existing flow with **a** update, probably not the last one, as there are no changes from the last RC to stable except for the version number, so at least 2 days of the same update won’t kill it.

How do I “downgrade” from the beta to the stable 5.0 release?

Currently there is no need to downgrade, experimental and stable are the _exact same_ version now, just uncheck the “experimental” checkbox, then you will only receive stable updates afterwards.
