Shelly H&T Gen3

With the Shelly H&T (Humidity & Temperature) Gen3 WiFi Sensor, you have insight into the humidity and temperature in your home or office. Often underestimated, but humidity is very important for your health, and that of your home (think of mold, for example). Humidity is recommended to be between 30-50 percent, with an ideal temperature of 45 percent. With the help of the Shelly HT, the display and the free App, this is a piece of cake. Create smart scenes (scenarios) and automatically turn on the humidifier with the Shelly WiFi Plug, automate your ventilation system, and automatically switch on your electric (floor) heater or Shelly TRV for a comfortable temperature in the (bath) room. Works stand-alone, so no need for an expensive Hub or Gateway.

Shelly H&T Gen3

The Shelly HT works on 4x AA 1.5V batteries (approx. 1 year, batteries not included) or via a USB-C connection (for more frequent reporting) and can be placed wherever you want, on the wall or with the included stand, as long as it is close to WiFi range. With its beautiful design and low-consumption E-ink display and with the choice of 4 colors, the sensor fits into any interior. The sensor continuously measures the humidity and temperature in its immediate vicinity, and stores this data in the cloud for free for up to one year. Through the free App, you can access the data and easily create smart scenes, with full control over the humidity and temperature in your home or office, for a healthy and comfortable climate.
Perfect to combine with the Shelly Plug or Shelly Plus 1 relay switch.

Open de back of the Shelly Temperature and Humidity sensor, press the button to connect via WiFi via the free Shelly App, and pair the sensor. It couldn't be simpler! Make sure you "wake up" the Shelly H&T by pressing the button before saving changes. And if you want to pollen more often by means of lower threshold values for more up-to-date information, but don't want to change batteries all the time, connect it via the USB-C connection. The Shelly H&T then sends more frequent updates of the temperature and humidity.

Do you want to attach the Shelly H&T Gen3 safely to the wall? Select the Shelly H&T Gen3 Wall-Mount at Order Together. Its non-removable without a screw-driver, handy for in office or public rooms. Please note, the USB connector is not accessible anymore.

The Shelly Plus HT Gen3 has the new Shelly ESP-Shelly-C38F 8MB flash chip built in, and so can be upgraded to Matter later. And allows you to flash your own or alternative firmware, such as Tasmota, for example. This does require a USB-to-UART 3.3V and minimum 350mA adapter. Flashing is done via the pins on the inside. CAUTION: since this sensor is regularly in sleep mode to save battery power, we do not recommend flashing unless you know exactly what you are doing! Also, flashing is not reversible for the Plus series!

Prefer not to use the free Shelly cloud service, but still want to be able to control your devices remotely? No problem. Shelly Plus H&T also supports basic MQTT (Message Queue Telemetry Transport) for reliable connections via a central broker: the MQTT broker. The devices involved communicate only with the broker and do not otherwise know each other. So they do not need to know the ip addresses and technical details of the other participants. So it is safe and reliable. it also supports Webhooks and REST API.
