I was trying to make a simple rule, once the fan is turned on, wait 30 min and turn it off. It wasnt terribly clear, but googling gave me some directions.
The issue is the navigation of this app.
Removing conditions seems impossible (Erase does nothing) and just getting around is super clunky. I had to stop and recreate my rule like 4 or 5 times because of inability to change things (most times it was something different)
Most of it was just a lack of options, however the erase condition definitely didnt work. I did erase, selected the condition (think i did an OK in there too) and it was ok went back to the list, still listed the condition.
