Shelly PLUS H&T GEN3 is the new GEN3 version of the popular H&T PLUS sensor 2024.

With a battery life of more than 1 year, the Shelly Plus H&T GEN3 ensures that you are always aware of the temperature and humidity in your home or office. Featuring a faster processor and dual memory, the Shelly Plus H&T GEN3 monitors the slightest change in conditions (up to 0.5 degrees temperature or 1% humidity variation) and helps prevent dehumidification or mould growth, while keeping your room comfortable. Compared to its predecessor, its display also shows the time in addition to temperature and humidity data.

The Shelly Plus can also run on battery power (4 AA batteries required) or from a mains charge with a USB-C charging cable. For battery operation, the Shelly Plus H&T promises a battery life of over 1 year, thanks to its super energy-efficient e-paper display. The Shelly Plus H&T is also equipped with a USB Type-C port, which when used, reports freshly measured data more frequently, up to every 5 minutes.

With a minimalist yet modern design, the device is a must-have in any office or home and not only allows you to monitor room humidity and temperature levels remotely via the Shelly app, but also to track data on the screen in the field. And of course, as always, you can build automations on the data and smartly control other Shelly devices.

Connected directly to Wi-Fi, no wiring or hub/central unit is needed to use it. Thanks to the ESP-Shelly-C38F chip, like other Shelly Plus GEN3 devices, it can be paired with your phone in seconds via Bluetooth.

Measured data is stored for 1 year in the free Shelly Cloud that comes with the product and can be viewed and downloaded in the free Shelly smartphone app.

The product is supplied without batteries. 

Pairing with your phone is simple and fast, using Bluetooth protocol, just like the other second generation Shelly Plus and Pro devices.
