What do you mean by that?
With ‘going through solid materials’ I meant that even in a drawer, the sensor can detect your presence, PIR does not.
Be aware that you cannot use 1 coordinator with 2 different zigbee integrations.
Do you have many zigbee devices and is your mesh not stable?
By switching to another integration:
- you have to pair every zigbee device again, and depending on your approach, configure everything that is related to those devices, again
- you might get some extra entities, that’s it
Also, be aware what the difference in wave detection and IR can do.
The thing with these mmwave sensors is: they are fairly new and different companies come with their version, some better then other.
Make sure that you understand it’s functionality right and optionally, search for experiences with the same device.
EDIT: also, if you have not done it yet, have a look at Zigbee networks: how to guide for avoiding interference + optimizing using Zigbee Router devices (repeaters/extenders) to get best possible range and coverage
