I've done a lot of remodeling over the years and most of my light switches are now in inconvenient locations. so I've largely switched to smart bulbs with wireless switches or put in inline wireless relay for my dumb lights.
I just leave the old wired switches in place and always turned on if that makes sense.
I've been using tuya zigbee relays for my dumb lights. they have a red wire and a black wire on each end. I simply spliced them into my existing wiring inside the fixtures where the wires come out of my ceiling, and tucked the boxes away out of sight.
one red in, one red out, connecting to the red wire on my light led ballast. and the same for the black wire, or sometimes blue.
I'm planning to replace the tuya relays with sonoff zigbee relays, but they have more than two connections in and out, and the wiring diagrams all seem to include a light switch in the setup. which I don't want.
1. am I trying to use the wrong kind of relay?
2. if this is the right kind of relay how should I wire it up.
I specifically want to place them "after the light switch" , so that if the switch is turned off the relay is also turned off as it has no power. like an isolator switch in basic principle.
some of my switches are now behind cupboards or are difficult to access, or are co. plex multi way switches with poor labelling as to which wire is witch that I'd rather not disturb in case I break something, but I can access the ceiling wires easily from above.
this is an older UK ring with only two wires.
i have uploaded screen shots below for the tuya and sonoff products.
tbr tuya isn't the exact one, but it's close enough to give you a general idea.
I'm having to compromise on some things for domestic reasons, so I'm looking to do it this way rather than looking for alternatives.
