does plus time mean it happens earlier or does the plus add time to the sunset event (later)?
Plus means after sunrise or sunset. It digs up the time and adds (or subtracts) the offset from it.
It’s an offset. So the plus means it’s happening later. So if sunrise is at 6 AM and your offset is +1, the event would run @ 7AM
No, it would run at 6:01 AM. Offsets are in minutes.
I thought it was hours. My bad. Thanks for correcting me!
There’s a bug in Android SmartThings classic. Offset keyboard options omit + only - is avail. so you have to copy + to the clipboard and paste to Automation.
