Does Tewke Tap have a motion sensor?
This allows the device to adjust when the screen lights up. The display will automatically turn off when nobody is around and wake up as you approach. You can even configure specific "near" and "far" distance thresholds so the screen doesn't wake up unnecessarily if you are just walking past at a distance.
Beyond the screen, you can use this sensor in your home automations. Using the Automations feature in the Tewke app, you can set your lights to turn on automatically when someone enters a room, and turn off again a set number of minutes after the last movement was detected.
