I had the same problem. Hue replaced it as defective. Second one was still slow to respond. I paired it in the same room as the hub, then moved it where i needed it and let it sit for at least a few hours. Eventually it will work, just seems to take a while to become fully functional. Was this new since June of this year (manufactured in 2022)? From what i can tell it seems like these sensors made this year have some slight differences than older ones, and this laggy pairing seems to be a symptom of that. I can say that within 24 hours it was fully working as expected.
Btw, if you try to go to hue fir support expect a run around and general hassle. In my case it was about 4 weeks before they finally agreed to replace the device.
ok... I'll probably just start the replacement process.
Anyone have suggestions on a better motion sensor to use? I need more than one. I picked the Hue for the first test because I thought it would, well, Just Work.
My outdoor sensors work just fine, and the replacement does now as well, but it didn't immediately. @rickkwilhelm if it has been included for at least a day, see if it has gotten better. Mine definitely needed at least a few hours / a day to settle in, but it's worked reliably since. They don't work as flawlessly as I expected out of the box (like the outdoor sensors). But they do work after a day or so, as reliably as my outdoor sensors. Based on the reccomendations vs, my experience I'm inclined to think they changed something in this most recent production run, i just don't know what.
If you are talking about replacement with Hue, they will ask you:
A) if you have paired it to a hue bridge
B) if you have used it in the bridge with hue bulbs.
When I told them I had not, but paired it to Hubitat and it was not working, they questioned how I could know it wasn't working if it wasn't paired with the hue hub. They initially tried to void the warranty beacuse it was paired to a third party hub. They did eventuality relent and replace it.
I have also been having very good luck with the Ring Gen 2 Motion Sensors, they are Zwave, so a tad slower than ZigBee, but rock solid reliable. I included them into a C7 using SmartStart. They want to include with S2, ( based on @mavrrick58 recommendation) I left that alone and let it pair with it, and they have not had any negative impact on my Zwave mesh. I think I currently have 4 in service. One draw back , if you want Lux values, these do not provide that feature. But as a motion sensor they are very stable and very reliable.
