Shelly Button Add-On, black

The Shelly Button Add-On is a handy black surface housing designed for installing Shelly relays and dimmers outside wall boxes. It makes it easy to turn ordinary lights, fans or small appliances into smart devices without cutting into the wall or complicated wiring. The solution is ideal for rentals, renovations and situations where it is not possible to interfere with existing wiring. The Shelly Button Add-On is not intended for stand-alone use and requires a compatible Shelly relay or dimmer. The pre-installed, colour-coded cables make assembly quick and easy. Once connected to the Shelly relay, the device can be controlled via the manufacturer's app available for Android, iOS and Windows, in both Czech and English.
