Have you tried to repair the sensor (long press on the device tile → wheel → maintenance)?  
You must wake up the sensor during the repair process.  
You can also try to do the repair process near the Homey.

@Peter_Kawa, interesting how you come from the problem of an empty battery to zone activity. Should he now buy a new sensor every time the battery is empty? The main thing is that the flow doesn’t have to be changed? 😂  
(Just kidding)

Btw, there is a script available to repair all the advanced flows if a device must be deleted and re-added:
