Does it work without Home Assistant?

Yes. It runs ESPHome but has been used with SmartThings and Homey Pro. Home Assistant gives the smoothest experience, since ESPHome is native there.

Can it detect someone sitting still?

Yes. The 24GHz mmWave radar detects small movements like breathing and typing, which is the main reason to choose it over a PIR-only sensor.

The sensor unit, a 2 m USB-C cable, the 24GHz mmWave module and the Panasonic PIR module. You supply a 5V USB-C power source.

Does it need batteries?

No. It runs on USB-C at 5V and draws about 160mA idle, so it needs a nearby outlet or a USB power run.

How does it compare with a plain PIR sensor?

A PIR sensor is cheaper and faster to trigger but loses track of still people. The Presence One adds radar, climate and light sensing and Bluetooth for more reliable occupancy automation.

Is it worth the price?

If you automate lights or climate in Home Assistant and want reliable occupancy, one unit can replace several cheaper sensors. For a single hallway light, a basic PIR is enough.

Our take on the Everything Presence ONE

The Everything Presence One is a small ESP32-based presence sensor for Home Assistant and other smart home hubs. It pairs a 24GHz mmWave radar (25 m range, 100° × 40° field) with a Panasonic PIR for fast triggers, and adds temperature, humidity and ambient light sensing plus Bluetooth tracking and a Bluetooth Proxy. It ships with ESPHome pre-installed, so Home Assistant users get local control without cloud dependence. It is a niche, maker-friendly device rather than a plug-and-play consumer gadget.
