At CES 2026 Aqara announced the P100, a multi state sensor. For object and open/close monitoring.
It uses a CR2450 battery.
In the box there are two mini booklets, the sensor and protective cover handy when you place it where it can get wet. Though its stated to only be used indoors.
It can be used in Thread and Zigbee. But in Threads you can see it misses a lot of sensors with firmware 1.0.0.2
The Object Monitoring is only supported in Zigbee protocol with an Aqara hub. In this mode it will detect movement, tilt, vibration, and fall events in 3D space, while also monitoring orientation (face up or face down).
So with Matter you will miss out on support for sliding doors / windows, rolling gates, garage doors, 360-degree rotating doors and drawers for now.
Setting this sensor up was really easy to set up. Remove the tag so the battery start working, scan the QR code with HA for Matter and place it where you want it, calibrate for the correct state. I was done in less than 5 minutes.
My personal opinion is that you get more value out of this sensor when using it in Zigbee Mode.
Below the automation I have set up right now.
Plan to also add one so it turns off the radiator thermostat when my shutter is open for a set amount of time.
