SIRO Smart light switch type SL04210D

With the SIRO Smart light switch SL04210D you bring your existing electrical light circuits into the smart age. All you need to do is replace the SIRO Smart light switch with your old switch. Thanks to the WiFi and Bluetooth module built into the SIRO Smart switch, you can control your lighting system immediately and without a gateway via the Smart Life app (or Tuya app).

Of course, you have the full range of smart options as well as voice control with Google Assistant or Amazon Alexa at your disposal.


Easy conversion with suitable dimensions

As a standardized flush-mounted switch, the SIRO Smart light switch SL04210D can be easily installed in the existing flush-mounted box.

With an outer dimension of 80mm x 80mm and the switch surface of 50mm x 50mm, it fits into the most commonly used wall switches as well as multiple frames* when converted.

More control options with WiFi and Bluetooth

Equipped with a WiFi and Bluetooth module, the SIRO Smart light switch SL04210D can be controlled via WLAN as well as Bluetooth. You have 3 options:

  • Wifi connected to your smartphone via in-house WLAN and can therefore also be controlled remotely.
  • With Bluetooth, directly connected to your smartphone, whereby only internal control is possible, but your data remains internal.
  • Connected to your smartphone via a gateway via Bluetooth and can therefore also be controlled remotely.

With all 3 types of control you can use the known functions from the Smart Life app, from time switch function, voice control via Google Assistant or Amazon Alexa, to the scene program. All of these conveniences can be realized by replacing a single switch.

Modern design with touchscreen

The modern design, the high-quality glass surface with touchscreen, gives the switch not only smart functions, but also beauty and shine.
