Switching actuator and meter – flush-mounted

Make your lights and devices smart the easy way, and control them automatically to suit your needs: For example depending on time of day or brightness. To do this, use the switching actuator and meter for installation in the flush-mounted box.

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.

The intelligent actuator for any job

You can easily adapt the electronic devices to suit your everyday life. And at any desired time - also depending on events such as sunrise and sunset.

Switch all the electrical devices in your home as desired: grouped together, individually automated, via Homematic IP pushbuttons and remote control, by voice command, directly on the device or via your smartphone – at home and when you're out and about.

Invisible installation

Its compact design allows the actuator to be easily installed in standard flush-mounted boxes. Wiring is particularly easy and safe thanks to the screwless terminals.

Alternatively, it is also possible to install the actuator in surface-mounted distribution boxes (e.g. ELS Spelsberg Abox 25) in basement rooms or in protected outdoor areas.

Power consumption under control

The 16 A switching actuator with meter quickly identifies power guzzlers in your home and switches on devices only when they're needed.

The measuring function records the consumption values of the connected devices and evaluates the costs via the app.
