Philips Hue Outdoor Sensor vs Shelly Blu Motion

The Philips Hue Outdoor Sensor wins overall with IP54 weatherproofing, a higher owner rating, motion, light and temperature sensing, low-battery alerts, wide 12m/39ft coverage, and support for HomeKit, Alexa, Google, SmartThings and Home Assistant. The Shelly Blu Motion is cheaper and excels as a tiny indoor sensor in a Shelly home.

Weatherproofing and reach. The Philips Hue Outdoor Sensor is IP54-rated and detects over a wide 160-degree field to 12m/39ft, adding temperature sensing, while the Shelly Blu Motion is a compact indoor-only Bluetooth sensor with motion and lux, reaching about 9m/30ft.

The Philips Hue Outdoor Sensor covers more, with a 160-degree horizontal field and 12m/39ft range against the Shelly Blu Motion's 9m/30ft. The Hue also adds a temperature sensor and low-battery alerts, though the Shelly counters with a far lower price and up to five-year battery life.

Both need a bridge, a Hue Bridge for the Philips Hue Outdoor Sensor and another Shelly device or BLU Gateway for the Shelly Blu Motion. Only the Hue is weatherproof; the Shelly Blu Motion is indoor-only and performs poorly outside even under cover.

Buy the Philips Hue Outdoor Sensor if you need weatherproof, long-range outdoor lighting automation with light and temperature sensing, low-battery alerts and broad ecosystem support. Its wide detection and 2-year warranty suit porches, driveways and garages.

Buy the Shelly Blu Motion if you already run Shelly hardware, use Home Assistant, and want a tiny, low-cost, fast indoor sensor with a lux sensor and multi-year battery life. It is the value pick for indoor Shelly-based automations.
