Keep your cool – or warmth! This handy little sensor is perfect for every room.
The Sonoff Zigbee Temperature & Humidity Sensor is a straightforward way to add smart sensing to your home. Whether it’s monitoring a specific room or keeping an eye on your greenhouse, this sensor integrates effortlessly into your Zigbee network.
With a pre-installed battery that lasts over four years, maintenance is minimal. Installation couldn’t be easier – the back of the sensor is magnetic so it will stick to many metal surfaces found around the home or you could use the included 3M adhesive tape and metal mounting plate to place the sensor wherever you need it.
Keep Heating Costs Down
In your home automation setup, you can create rules for temperature or humidity changes in a room. These rules can trigger notifications or events, such as turning the heating on or off. You can also check the temperature throughout your house at a glance, making it easier than ever to manage your home environment efficiently.
To use Zigbee devices, you’ll need a Zigbee-compatible USB dongle connected to an always-on computer (a Raspberry Pi is ideal!) or a dedicated smart home solution such as the excellent Home Assistant Green (with Zigbee dongle) or the Sonoff iHost.
Whether you’re monitoring the spare room, optimising greenhouse conditions, or ensuring your pet snake Medusa is comfortable, the Sonoff Zigbee Temperature & Humidity Sensor is a fantastic addition to your smart home. 🌡️✨

What Is Zigbee?
Zigbee is a wireless standard enabling low-power, secure connections between smart devices. Widely used in home automation for devices like thermostats, sensors, and locks, its energy efficiency allows some devices to operate for years on a single coin cell battery.
The key benefit of Zigbee is its local operation – no cloud subscriptions or internet connections are required. Everything can remain within your home, making it both highly secure and resilient against internet outages.
Major brands like IKEA, Philips Hue, Tuya, and Sonoff support Zigbee devices, allowing you to integrate products from different manufacturers into one smart home system. This ensures you’re not locked into a single vendor – brilliant!
With an indoor range of 10–100 metres and extended outdoor coverage, Zigbee’s mesh networking ensures reliable communication, even if some devices go offline. Its robust security features, including encryption and key protection, safeguard your smart home and keep it under your control.
