• The device is intended for use in living rooms, especially bedrooms.
  • It should not be exposed to increased humidity (e.g. in bathrooms), direct sunlight or mechanical loads such as shocks etc.
  • There are no dangerous voltages in the housing. The Arduino is powered via USB cable.
  • The powerbank at the other end of the USB cable is powered by a 5-volt switching power supply, which in turn is plugged into an electrical outlet. Only this part carries mains voltage.
  • It must be ensured that both the power supply and the Powerbank remain free of dust and objects (blankets, plush toys, magazines, etc.) that could hinder their heat dissipation. Otherwise there is a fire hazard!
