I’m curious about the battery life of the Aqara FP300 mmWave and PIR sensor. I currently use a few single-zone Zigbee mmWave and PIR sensors from another brand, powered by two AAA rechargeable batteries, which last around five months. Does anyone know if the FP300, with its multi-sensor capabilities, offers similar battery performance? Any insights on its specs would be appreciated!

Given that it has both PIR and mmWave, I’d assume the mmWave sensor only kicks in once the PIR detects initial motion. That would be a smart way to conserve battery, using PIR as a trigger and mmWave for fine presence detection.
Battery life could vary significantly depending on how often someone stays within the mmWave detection zone the longer you linger, the more juice it likely sips.

Do u thing the sensors will be exposed separately?

I would assume both the PIR and mmWave sensors will be exposed in the app at least for automation triggers. That said, I’m guessing the actual switch from PIR to mmWave will happen internally on the device.
I’m most curious about is the delay between the PIR trigger and mmWave activation how seamless is that handoff, and does it feel responsive enough for real-time automations?
Won’t know for sure until I get my hands on one.
Hello @K-Unit
The sensor will operate on battery power and from the mains, I think it is too early to talk about autonomy, since no one has received it yet and time has not passed to test the autonomy, time will tell how autonomous it is.
