Product detailed description

Shelly H&T Sensor Gen3 - WiFi Temperature & Humidity Sensor with Display (Ivory)

Thanks to its smart features and battery life of up to 1 year, the Shelly H&T Gen3 ensures you always have a perfect overview of the temperature and humidity in your home or office. The new Gen3 version features a faster processor, double the memory, and reports even the smallest changes (0.5 °C and 1%), helping you prevent mold and maintain a comfortable environment. Compared to its predecessor, this version also displays the current time.

The sensor is powered by 4x AA batteries (not included) or via a USB-C cable. When running solely on batteries, it lasts up to 1 year thanks to the ultra-efficient e-ink display. Additionally, when powered via USB-C, data reporting becomes much more frequent (e.g., every 5 minutes).

Ecosystem Without a Hub

Connecting directly to your WiFi means you don't need a HUB. With the built-in ESP-Shelly-C38F chip, you can pair it with your phone in seconds via Bluetooth. The measured data is stored for free for up to 1 year in the Shelly Cloud.

• Prevent Humidity (With Shelly Plus 1): Connect a ventilation fan to a Shelly relay, and it will automatically turn on when humidity rises.
