Keep your cool - or warmth! This handy little sensor and display combo is perfect for every room.

The Sonoff Zigbee LCD Smart Temperature Humidity Sensor is a simple way to add both smart home sensing and climate displays throughout your house. Stick it to a convenient ferromagnetic surface or pop it on a shelf or counter-top using the built in kick stand to have a real-time view of the local conditions.

It comes with a battery pre-installed that will last for over two years allowing for minimal maintenance.

Keep heating costs down

Within your home automation setup you can create rules for what happens when the temperature or humidity change in a room. These rules can trigger notifications or events such as turning the heating on or off. You can also easily, at a glance check the temperature throughout your house.

To use Zigbee devices you'll either need a Zigbee compatible USB dongle connected to an always-on computer (a Raspberry Pi is ideal!) or a dedicated Smart Home solution like the awesome Home Assistant Green (+ Zigbee Dongle) or Sonoff iHost.

Whether you're monitoring the spare room, perfecting the growing conditions in your greenhouse, or ensuring that Medusa (your pet snake) is comfortable the Sonoff Zigbee LCD Smart Temperature Humidity Sensor is the ultimate addition to your Zigbee network.

Stay cool, stay warm, but most of all stay connected! 🌡️✨

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 run for years on a single coin cell battery.

It has many benefits but the biggest one for us is its local nature, there's no cloud subscription or even internet connection required - everything stays within your home if you want it to. This makes it both incredible secure and also resilient to internet connection outages.

Many big brands have Zigbee supported devices including IKEA, Philips Hue, Tuya, and of course Sonoff. This means you can combine devices from different manufacturers into the same smart home setup ensuring you're not locked in to a single vendor - nice!

With an indoor range of 10–100 meters and extended outdoor coverage, Zigbee’s mesh networking ensures reliable communication, even if some devices go offline. Security features, including encryption and key protection, safeguard your smart home, keeping it secure and under your control.
