Measuring and reporting

On batteries

When running on batteries the Device behaves as follows:

  1. Wakes up every minute to do a measurement. If there is a 0.2 °C temperature or 3% humidity difference the screen updates. The default threshold for reporting is a change of 0.5 °C or 5%. If the change is less there will be no report sent.

  2. If for two hours there is no report based on threshold values, the Device unconditionally (disregarding threshold values) reports its status to Shelly Cloud and other connected channels.

  3. Due to self-heating a cool down period of 5 minutes is imposed. During this period the Device would not wake up at all.

On USB power supply

If powered via its USB port the Device will wake up every 5 minutes, perform a measurement, update its screen, unconditionally report to all connected channels, and sleep for 5 minutes.

User initiated report

If the user presses the Reset button (behind the cover) the Device will wake up, perform a measurement, update its screen, unconditionally report to all connected channels, and sleep for 5 minutes.
