The Sunis wirefree IO is a separate sensor that can be used to roll in or out sun blinds (such as screens) or shutters based on measured sunlight.

It is only suitable for motors with the Somfy IO system.

You pair the Sunis with any screen or roller shutter, which should close automatically when you get too much sunlight.

You can also link the sensor to the Tahoma Switch and control the motors from there.

Linking to the Tahoma gives you more options.

Even more options via Tahoma

If you add the Sunis sensor to your Tahoma Switch, you don't have to connect it separately to each motor.

This saves you time.

You can then easily create a program that tells the Switch what to do when there is too much light.

And also which shutters or screens should react.

You can also see in the Tahoma app how bright the sun is at that moment and how much sun there has been recently.

Combining light and temperature sensors

Too much light inside is annoying, but if it gets too hot, that's not nice either.

Hence, there is also a temperature sensor. This is the Thermis IO (you can find it here) and it is the perfect companion to the Sunis IO.

By combining them, you can make sure in winter, for example, that a room does warm up because of the sun. Then when the room has reached a certain temperature, the screens go down

Even though there may not be that much sun.

In summer, by combining the Sunis and Thermis, you can keep your room nice and cool.
