But I do not want to buy a Hue bridge just to use a motion sensor. I believe one of the strong points from homey is not to need the bridges for all brands. And when i do not use a bridge the Hue bulbs make a nice Zigbee mesh for other sensors (xiaomi a.o.) as well.
Only thing I noted that the zwave range is not really big. And I only use zigbee for the rest of my stuff. But as the sensor is in the same room as homey it is very stable. Just keep that in mind, unless you have some other zwave devices to form a mesh network.
My Philips Hue Motion detectors work, in the main. Occassionally, I have to reset one or two, but I think it has something to do with the batteries. One day 100%. the next 0%. I replace the batteries, reset it and then it works again. I have 6 of them. All report Lux and temperature, too. And without the Bridge, using latest Philips Hue ZigBee.
