Once #31 is implemented, it will be important to introduce power saving features. When the device is not in use for 30 seconds, put the device into sleep mode. Pressing the button should wake the device.

  • Use ESP32's deep sleep mode when on battery power
  • Turn off the TFT backlight when on USB power

The number of seconds to wait before triggering sleep mode should be configurable.
