Nursery Climate Monitor

The Shelly H&T Gen 3 is a wall-mountable temperature and humidity sensor that connects via Wi-Fi and Bluetooth without needing a separate hub. An e-paper display shows readings and a built-in clock, while a USB-C port and low power draw keep it running on batteries. It is designed for parents who want real-time nursery conditions and automated alerts on their phone.

Upgrade From Basic Hygrometers

This replaces standalone analogue or single-protocol sensors that cannot trigger automations or log history in an app. The jump is worth it when you need scenes that activate a fan, heater or humidifier based on live data, or when you want Matter-ready firmware updates through the 8 MB Shelly chip. It is not for buyers who only need a local readout without a smartphone.

Wi-Fi And Bluetooth Range Limits

The sensor relies on your home Wi-Fi and Bluetooth radios, so thick walls, metal enclosures or long distances to the router can delay reports or break automations. Battery life will shorten if the device wakes frequently to reconnect in a weak signal zone. It is not for installations where a wired or mains-powered sensor is required for guaranteed uptime.

Questions about this item

Does the USB-C port on the Shelly H&T Gen 3 need a permanent cable for power or is it only for charging?

The USB-C slot is used to recharge the internal battery; the sensor runs on battery power between charges so it does not need a permanent cable.

How do I add the sensor to the Shelly app without a separate hub?

Open the Shelly Smart Control app, tap Add Device, choose H&T Gen 3, and follow the Bluetooth pairing steps; the sensor connects directly to Wi-Fi so no hub is required.

What maintenance does the e-paper display need over time?

The e-paper display is passive and has no backlight, so it requires no cleaning or calibration; only the rechargeable battery will need periodic USB-C charging.
