Trying to Connect a Relay Switch to a Light Fixture with Old Wiring

[JDRoberts]

Just realized you said GU 24 – – by any chance are you in the UK? If so, the smart switch covers and mentioned are not available there, as they are shaped for typical US switches.

But there is a very nice battery operated wall switch made by both devolo and Popp and a community member has made a device type handler for them so they would work with smart things just like the one that I pictured previously.

And then a different community member has devised a frame for them that can fit over an existing UK style switch.

So same idea, just different devices are available in the US and the UK. They’re all listed in the remotes thread that I linked to above.

Here’s the link for the frame for the UK style.

Design for a frame & cover to let you "replace" a light switch with no changes to electrical wiring needed

Hello everyone! Here in the UK we don’t normally have a neutral wire in the wall boxes behind light switches so that rules out replacing light switches with “smart” switches directly without extra costs. However, you can get battery powered switches, but if you’re like me you don’t want to have two sets of switches and have someone accidentally turn the lights off at the wall using the original switch… This way you can put a z-wave relay up in the ceiling connected to live, Earth and neutral and then toggle the lights on and off w from the battery switch or your phone via ST app. So I’ve designed a cover (the central item in the render below) that fits over the manual light switch, is held in place with magnets and provides a mount for a z-wave battery operated switch: [image] The g…
