I have had the same experience as @bptworld... working well for me so far.
Pretty decent like Bryan said, you can also adjust the detection distance which I assume tracks with the power level. I have one in our den and it works pretty much everywhere in there even when someone is laying on the couch - sensor is behind the couch on top of a cabinet.
I've always treated it like it was regardless..
usb powered, comes with a nice long cord and charger.
No dropoffs so far but my oldest device in our powder room has only been installed since mid August.
Additional Notes:
If looking to use for motion activated lighting I would recommend using in conjunction with a traditional motion sensor as the FP1 is a bit slow for the initial detection. I use the motion sensor for a fast "hit" in order to turn my lights "on" and then the FP1 for the "inactive" in order to turn lights "off".After testing the sensor seems plenty fast... thanks to @cnelson.sc for mentioning it in another thread...- Can install via the Hubitat Package Manager. Use @kkossev's excellent "Aqara P1 Motion Sensor" driver. (yes P1 not F1)
