I am trying to find a zigbee movement sensor that would be flush mount for putting in a ceiling. And if possible hardwired 240vac for Australia so no batteries.
I have seen flush mount Z-wave but would rather stick with zigbee if possible.
If you find one let me know! I couldn't find anything that suited so ended up with the z-wave multi sensor 6 and took 12v to it then used a 12-5v usb converter.
I'm still trying to convince my company to make one as I think people would buy them.
The NYCE Ceiling Motion Sensor is a very good ZigBee motion sensor. It is not "flush" mounted but is small enough in size that it does blend very nicely on the ceiling. It is battery powered but the batteries last a long time in these units.
I use the " xiaomi Aquara motion sensor ", they are battery but they do last for ages. Very small
and work well. You can put them pretty much anywhere and you don't notice them...
I do not use the stands at all, top of door arcs or just on a shelf.....
