They're probably gone now, lol, but I thought I'd chime in that I'm happy with my Zooz
ZSE18LR replacements. Set at its most sensitive, it's VERY sensitive, almost what I would think of as "presence". Set at a lower sensitivity, it ignores the cat's night stalking, most times, lol.
@emmaharrismill , I had two big problems with my Hue zigbee motion detectors: one after a power outage, and the other out of the blue. All but one or two dropped off. I fooled around a lot after the power outage and got them all back. The second time, I refused to touch them, and they didn't come back on their own for days. I subsequently got rid of them, and now have only one zigbee sensor: a Sinope propane tank monitor, which never totally dropped.
Now, in my case, the second incident could have been related to the WiFi cameras I have been adding, from having none. My C8 hub was set at the recommended channel (in USA)...20 I believe.
I was also down on zigbee because of the 8 second radio reboots. I tried fixing that by replacing all my zigbee plugs with the latest and greatest zigbees, but that didn't solve it. So, I replaced them with Z-wave plugs, and only had about 12 Hue motions, one door contact and the propane monitor. No more radio reboots.
I am going Z-wave Long Range where I can afford it...most of my battery devices are LR now. My Ecolink devices have been great though, and I'm loath to replace them. The mains-powered switches would be a major cost, and potentially unnecessary.
Maybe a zigbee expert will chime in. Perhaps a European zigbee expert, if that's where you're located.
