Product notes
CSA End Product primary 0x0107 Occupancy Sensor (Thread+Bluetooth). Maker: Matter over Thread to Apple Home, Alexa, Google Home, SmartThings, Home Assistant. Illuminance secondary — maker notes Alexa currently doesn’t support the light sensor. Multi-zone presence via Meross app.
v0.50 High add (3-SKU thicken). CSA25952MAT47268-24 primary 0x0107 + Meross shop retail ($33.99). Distinct from older Meross Wi-Fi presence cert CSA241F5MAT43176-24 PID 0x4201.
How it differs from the type answer
- mmWave radar + PIR dual detection (still-presence) vs PIR-only Eve Motion.
- Illuminance endpoint may be absent on Alexa (maker note) — SKU-level caveat for light_sensor Alexa cells.
- Platform exposure follows motion_occupancy (+ light_sensor also-type); no SKU-level automation test this pass.
