Matter Smart Switch

Matter smart switch wired in-line on the live wire of a light or appliance.
Typical uses: retrofitting ceiling lights and downlights, zoning office lighting, adding remote on/off to non-smart appliances.
Works with Apple Home, Amazon Alexa and Google Home at the same time, so you are not locked into one ecosystem.
Beyond app on/off it also supports timer, schedule and LAN control.
A compact body that hides inside a false ceiling, a light cove or a junction box.
A Matter hub (HomePod, Echo, Nest Hub and similar) is required, so please confirm you have one before ordering.
