Temperature and humidity sensor Shelly H&T Gen3 Matte White, E-ink display, WiFi, app control

The Shelly H&T Gen3 Matte White is a WiFi temperature and humidity sensor with an elegant design, a matte white finish and an e-paper display that remains permanently visible, with no extra energy consumption to keep the image on screen. It is powered either by 4 AA batteries or via a USB-C cable, offering flexibility depending on where it is mounted.

The sensor works independently, directly on the local WiFi network, with no need for an additional hub or gateway. It displays the exact time (NTP synchronised), the current temperature and humidity, making it suitable for the bedroom, living room, office or child's room, where it can be used both as an indoor weather station and as a trigger for air conditioning or ventilation automations.

The data can be integrated into Shelly scenes to automatically start air purifiers, dehumidifiers or air conditioning systems when values fall outside the desired range, helping to maintain a healthy and consistent indoor climate.

Practical use cases

• Monitors the temperature and humidity in a room, useful for preventing mould or maintaining an optimal climate for plants or pets.
• Can automatically start a dehumidifier or ventilation when humidity exceeds a set threshold.
• Sends notifications if the temperature suddenly drops or rises, useful for monitoring a holiday home.
• It can be used to automatically adjust a heating system based on the actual temperature in the room, not just the reading at the central thermostat.

Technical specifications

An elegant, self-contained sensor, perfect for monitoring thermal comfort at home, with no extra cables and no dependence on a gateway device.
