FAQ's

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. 

To prolong the Battery life, the Shelly H&T sleeps in between taking readings and when a report of the temperature and humidity is not needed. 

To make setting changes you will need to manually wake the Shelly H&T by removing the cover and pressing the button sticking up next to the battery. 

If you have set the Shelly H&T to report on very small changes or on a frequent schedule, it will dramatically decrease battery life, especially in areas where there are frequent changes such as being close to an air conditioning unit. To prolong battery life, try increasing the variance change for the reports or even turning off the Humidity trigger updates.

The Shelly H&T is a small device and can easily be affected by the heat produced when holding it or even its own circuitry if it has been awake for a long period of time. When it sleeps in between reading it will return back to room temperature. To ensure the most accurate readings, leave the Shelly H&T undisturbed and set from the most infrequent readings and schedules.
