This Zigbee Temperature and Humidity Sensor is IP65 rated so it can be used to monitor outdoor conditions or in damp or dusty environments. The Sonoff Zigbee LCD Smart Temperature Humidity Sensor is a simple, robust way to add both smart home sensing and climate displays throughout your house or garden. Stick it to a convenient ferromagnetic surface or hang it using the included loop - great for attaching to bathroom fixings. It comes with a battery pre-installed that will last for over two years allowing for minimal maintenance. Get Smart, Automate! Within your home automation setup you can create rules for what happens when the temperature or humidity changes in a area. These rules can trigger notifications or events such as turning a dehumidifier on or off or opening a window. You can also easily, at a glance check the temperature throughout your house or garden. You'll need a Zigbee gateway present on your home network to be able to log data and trigger automations. This could be an iHost or Zigbee Bridge if you want to use Sonoff's eWeLink app. Alternatively you could connect to a Raspberry Pi running Home Assistant (or a Home Assistant Green), equipped with a Zigbee dongle. Whether you're monitoring the outside temperature, perfecting the growing conditions in your greenhouse, or ensuring that your pet lizards are thriving the Sonoff Waterproof Zigbee LCD Smart Temperature Humidity Sensor is the ultimate addition to your Zigbee network. 🌡️✨ Why we love it As well as feeding data back to your smart home controller this lovely little unit also includes a large, clear LCD display so you can see its readings at a glance without having to grab your phone.

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. Learn more about Zigbee on the official Zigbee website.
