USB power supply for Shelly H&T Specification



Brand Information

Shelly logo Shelly is a home automation lineup including various accessories with multiple purposes. Shelly devices are designed and developed to provide solutions tailored to your needs


No as the fully powered device and chips generate a little heat which could affect the accuracy of the returned results. 

The Shelly H&T will still sleep after it has reported the temperature change. You can however change the temperature reporting threshold from every 1c to every 0.5c. 

The Shelly H&T reports changes in the Temperature or Humidity threshold changes of 1 or 2 when powered by a battery and every 0.5, 1.0, 1.5 or 2.0 when powered by the USB Power Supply.

No, the Shelly H&T is designed to report the changes of the Temperature and Humidity thresholds which are set in the Shelly Cloud app or the device Web UI. When using the USB Power Supply, the Shelly H&T sends a further update every 10 minutes.

We strongly recommend that you use fixed IP addresses for your Shelly Devices. We have noticed that the battery tends to drain much quicker when a fixed local IP Address is not set. It also makes it easier to access the Web UI of the Shelly Device if you need to later. 

The Shelly H&T does not remain connected unless there is a change in the Temperature or Humidity threshold. When you add the USB Power Supply it does send a further update every 10 minutes in case there has not been a change to report.
