what exactly is the difference? Which one should i take?
Thank you in advance!
I think I read the occupancy is another driver for the same device, created separately so the old one is still available. Some had better luck with the occupancy version I believe. But I may be wrong. Maybe the [APP] Philips Hue Zigbee thread is a better place to ask.
You are correct!
The Motion driver is the legacy driver that many users have installed since before and make use of the standard Zigbee clusters. It uses a counter for resetting the alarm efter an initial motion detection.
The Occupancy driver makes use of the Philips Hue Manufacturerspecific Zigbee cluster enabling support for the device to enable/disable the alarm based on movement and absence of movement.
Installing a new device I advice to use the occupancy driver.
