I installed one of the Blue mmwave dimmers (VZM32-SN) and am using it in Smart Bulb mode to control some Wifi (LIFX) lights. I have an automation setup for simple on/off and presence detection and it works (still lots of work to do here for overrides).
I however have an issue… When sitting on the sofa within the detection zone it loses presence, then if somebody moves occupancy is detected again and the lights turn on (repeats endlessly)… this is not at the edge of the detection zone since when somebody enters\leaves the door behind the sofa it catches this fine. i have validated that the sensitivity is at high (2,) what other params to i need to set or look into?
Thanks for the help and so glad i finally got these! 2 more to install soon.
I had the same issue in my office and my swivel chair, If my back was to the sensor working at one desk it would go to no occupancy. My solution was to add time to this parameter:
mmWave Detection Timeout
I put in 300 seconds because I wouldn’t be idle in that chair position for more that a few minutes. I found it works good for our dining room also but in that case I did 600 seconds just to be safe.
I think this sensor has a very hard time with people sitting on soft things (even at the most sensitive setting). The one I have in our living room is the same as what you described. If I sit on the couch, the sensor eventually loses track of me (usually within a couple minutes or less). If I stand in front of the couch (so only a few inches of difference in terms of distance from the sensor), I can stand very still and the sensor basically never loses track of me. I’ve ended up having to add another mmWave sensor (the Everything Presence Lite) sitting on the media cabinet directly facing the couch to address this. That device doesn’t have the same problem tracking me sitting on the couch.
