Screen off option? #461

Closed Digital-Ark closed 6 months ago

Digital-Ark commented 9 months ago

Hardware Version: LYWSD03MMC B1.7 Software Version: 4.6

Checking the screen off box seems to no longer update the screen, but it doesn't go blank.

Perhaps I don't understand correctly, and not updating the screen saves power. I was hoping the whole screen would be blank.

My use case is a freezer sensor, where the screen is too cold to operate correctly.

After enabling the option, you need to restart the thermometer using power. Remove and insert the battery. There is no documentation for the LCD display controller - only this shutdown option is used.

Thermometers with CR2032 are not suitable as a freezer sensor. Use https://github.com/pvvx/BLE_THSensor.

Excellent, thank you.

I have 3D printed a case that uses 2 "AA" batteries instead of the CR2032 for my use case, it's working well.
