If you do not have a traditional in-wall junction box for your smart switch or control panel, this is what you need. This box is designed to be installed on the surface of a wall rather than recessed inside it, and a smart switch can be installed into it.
It is compatible with smart wall switched, the Shelly Wall Display, Sonoff NSPanel, Sonoff NSPanel Pro control panels, too.
It's made of heat resistant plastic, so it's safe choice to install the control panels or wall switches into it.
