I don't see the advantage of this over any smart bulbs (Hue, Ikea, TP-Link...) and a battery-powered switch stuck to the wall. Actually this is a lot more effort because you have to wire the module in rather than just changing the bulb. You still need to keep the old switch and it needs to be 'on'. Somebody's going to press that. I'm after a switch based solution where the existing switch is removed and replaced with a mains powered smart switch. In your previous post you mentioned "a light switch which trickles enough electricity to power an RF receiver while keeping the lights off - controlled by a WiFi connected hub." - did you get anywhere with that? Oh and I'm really curious about how these switches are magically powered!? 🙂 Thanks!
