## Description

The Shelly Button Add-On is an accessory that enables you to turn lights, fans or small appliances into smart devices with the addition of a Shelly relay. Ensuring the least disruption to your installations, this accessory lets users install relays and dimmers outside of wall boxes, giving you surface-mounted control anywhere you need it.

Shelly's Button Add-On has a retrofit-ready design making it easy to create smart night lights, fans and other appliances without having to install into your walls or pre-existing units. This accessory also comes with pre-installed colour-coded cables for fast connection to Shelly relays and simple installation.
This device is compatible with a large range of Shelly switches, including Shelly Plus, Gen3 and Gen4 relays and dimmers - allowing you to customise your setup to your device and it's individual needs.

The Shelly Button Add-On is ideal for rental properties or temporary deployments as no in-wall installation is required. If the black version doesn't match your home design - this product also comes in a white design!
