I am looking for some low costs ZigBee or maybe Z-wave switches that do not require a neutral line. My home is older and most switches don’t have a neutral line available. As a bonus some outlets that I can put in boxes vrs the plugin adapters would be helpful too.
So they need to be battery operated? Which means you can’t have the relay at the button, it needs to be somewhere you can power it properly. Maybe some combo of sonoff type relay at the light fixture, and battery operated button instead of the old light switch?
This would work I think.
