Brightness measurement
The Sunteis Solar io solar sensor continuously measures the current solar radiation and triggers the shutters or blinds to be lowered and the awning to be extended if the brightness is too high. This keeps your living spaces cool and your furniture and plants protected.

Temperature measurement
In combination with the TaHoma Switch smart home control centre, you can also view the outside temperature via the Sunteis Solar io and the automatic solar function is automatically deactivated in colder temperatures. This makes it easy to use the sun's rays to heat your home.

Simple installation
Thanks to the solar-powered technology and wireless connection via io radio, installation is particularly easy as no wiring is required. Installation is quick and effortless with the supplied wall bracket.

Control your home automatically depending on the sunlight and outside temperature. The Somfy Sunteis Solar io brightness sensor continuously monitors the current level of solar radiation. As soon as a set brightness value is exceeded, the sensor immediately informs your sun protection system, for example your wireless roller shutter motor, which automatically lowers. This keeps your home pleasantly cool while effectively protecting furniture and plants from excessive sunlight.

Why heat protection is so important
Summers are getting hotter and hotter and heat protection in the home is becoming increasingly important. With a smart home centre and networked sun protection, you can prepare your home optimally for the hotter months of the year. Reduce the temperature in your home by 4-7°C with automatically controlled sun shading with smart sensors, such as the Sunteis io solar sensor.
