Sensors

Shelly smart home sensors send an alert to your phone the moment something happens: a leak, smoke, an opened door, motion, or temperature and humidity outside the range you set. Most are wireless and battery-powered and join your smart home with no wiring.

Flood sensors

Shelly Flood Gen4 detects water on the floor and sends an instant alert: under the sink, next to the washing machine or water heater, in the basement or in the parking garage. It comes with a leak-detection cable, runs on batteries, also detects rain, and the cable can be extended. More on preventing floods at home.

Wireless motion sensors

Shelly BLU Motion detects motion and turns on the lights, or sends an alert when nobody is home. It's wireless, with a long-life battery, and connects through any Shelly Plus, Pro or Gen3 device you already have at home.

Temperature and humidity sensors

Shelly H&T Gen3 runs on batteries or over USB, and the small BLU H&T is water and dust resistant (IP54), so it works on a balcony or in a greenhouse too. The readings can switch on an air conditioner, a heater or a fan. More on controlling the temperature at home: too hot or not warm enough?

Door and window sensors

Shelly BLU Door/Window detects opening and closing, the angle a window is open at and the light level, with a battery that lasts up to five years, in white and black. Use it for alerts, as part of an alarm system, or to trigger a scene, for example turning off the air conditioner when a window opens.

Smoke detectors

Shelly Plus Smoke Alarm sounds on the spot and sends an alert to your phone, and connects directly to Wi-Fi with no hub.

How they connect

BLU sensors work over Bluetooth and reach the app through a nearby Shelly device or a BLU Gateway. Wi-Fi sensors connect directly to your home network. Either way, there's no expensive hub and no subscription.

How much do smart home sensors cost?

What to do with the alert

Beyond the alert, a sensor can trigger an action: a flood closes an electric valve, motion turns on the lights, an opened door runs a scene. Automations are built in the Shelly app and also work with Google Home and Alexa and with Home Assistant. Not sure which sensors fit your home? Talk to us and we'll help.
