Battery radar/PIR presence and light sensor / Sensors
An appealing inexpensive presence sensor for a small room that already has Thread coverage. Battery placement and unusually detailed local tuning are its strengths. Choose it to keep a desk or reading-area light useful; skip it for a large room, precise person tracking or a system you expect to tune once without observing the results.
