Switching actuator and meter - flush-mounted

Invisibly integrating and measure electrical appliances.

The illuminated fountain is your eye-catching feature in the garden, and it looks especially good at dusk in combination with other lighting effects. Of course, the fountain should only be in operation at certain times so that you don't waste energy. For that you can also integrate your outdoor devices into your smart home. The switching actuator and meter from Homematic IP is installed in the flush-mounted box – invisible and protected against external influences. Via the free app, you can set time profiles and see exactly how much energy devices consume.
