Eufy Motion Sensor vs SwitchBot Motion Sensor

The SwitchBot Motion Sensor wins overall, with a lower price, a rated 3-year battery, a wider 110-degree angle, a built-in light sensor, and more integrations (Alexa, Google Home, SmartThings, IFTTT and Matter via the SwitchBot Hub). The Eufy Motion Sensor carries the higher owner rating but is motion-only and eufy-locked.

Features and reach. The SwitchBot Motion Sensor adds a lux light sensor and connects to many platforms through a SwitchBot Hub, while the Eufy Motion Sensor is motion-only and works only within eufy plus Home Assistant with a required eufy HomeBase.

Yes. The SwitchBot Motion Sensor needs a SwitchBot Hub for Alexa, Google Home, IFTTT or Matter (Home Assistant works via its API), and the Eufy Motion Sensor requires a eufy HomeBase. Factor the bridge you already own into your choice.

The SwitchBot Motion Sensor, at 110 degrees horizontal (with 55 degrees vertical), versus the Eufy Motion Sensor's 100 degrees. Both list a 9m/30ft range, though eufy owners find real-world reach shorter than the spec.

Buy the Eufy Motion Sensor if you already run a eufy HomeBase and want a highly rated, long-battery sensor for eufy cameras and automations. It is not the pick if you want a light sensor, a lower price or wider platform support.

Buy the SwitchBot Motion Sensor if you use SwitchBot, Alexa or Home Assistant and want an affordable sensor with a light sensor, a wide angle and a reset-on-motion timer. Note it cannot trigger Google Home automations, so Google-first users should look elsewhere.
