Smart Home case study: bathroom and restroom

Everyday scenarios in the bathroom and in the restroom


  • the lighting should only be on if the outdoor light sensor deems it necessary. If possible, you should have some basic lighting that you can enhance with spotlights. In this scenario, the spotlight is not needed.

Spotlight needed

  • the system turns on all lights regardless of the time of the day.

Night time

  • only the night light is on. You’ll really appreciate this setting when you go to the restroom at night and you don’t have all the lamps shining in your sleepy eyes. You need this lighting during power failures, too.


Extra tips:

  • water sensors to detect leaks can come in handy. They should be placed away from the bathtub so that they don’t get splashed.

  • the occupied sign is useful even in the family. Choose a door knob that can signal this.

  • if you use an electric towel warmer, it should come with a timer. You can set it to turn off automatically for example after 60 minutes.

  • Firing up your sauna should be connected to your smart home system. Even infrared saunas work better if they run for a few minutes before the session. Finnish saunas need 30-60 minutes to heat up before they can be used.


General lighting is controlled by the presence sensor. The presence sensors should be set at the sensor or at the home management system with delayed activation. This way lack of movement will not trigger the OFF mode immediately. For us, a delay of 120 sec works best.
