About this product
Shelly BLU H&T Display ZB Black is a compact Zigbee sensor that shows temperature, humidity and light level in real time right on an E-Paper screen, without opening an app. Unlike screen-less sensors, here you read the value at a glance from your desk, bedroom or nursery, while the built-in digital clock rounds out the display.<br><br>The device uses an SHT40 sensor for temperature and humidity and a three-level light sensor (dark, twilight, bright). It communicates over Zigbee 802.15.4 and Bluetooth 5 LE: to push readings into the Shelly Smart Control app or the cloud it needs a gateway, either a Shelly BLU Gateway or any Shelly Plus, Pro, Gen3 or Gen4 device acting as a Zigbee hub.<br><br>The E-Paper screen only draws power when it refreshes, and a power-save mode stops the refresh in darkness, so the two CR2032 batteries deliver up to 2 years of operation. Mount it on the included stand, on a wall, or on any metal surface thanks to the rear magnets.

Where it works
Use cases
In the evening you see on screen that humidity dropped below 40% and turn on the humidifier before bed.
Read temperature and humidity from the nightstand without a phone, with built-in clock.
When humidity exceeds the threshold, the gateway sends a notification to the app and to Home Assistant.
Continuously monitor comfort and get alerts through the gateway.
If the temperature drops below a threshold at night, a Shelly Gen4 device as a hub turns on the heating.
E-Paper display always visible on the desk, read at a glance.
