I can't find the commender1 with my smartphone.
I tried to turn off the power but when I plug it back in the Bluetooth it doesn't find it.
The light output is stored but not the on/off times.
Did you make sure open Bluetooth, GPS(for Android) and Location Service?
If yes app still couldn't find the light, download an app nRF Connect to scan all the devices and take screenshots of the Scanner page.
