It's annoying that smart plugs/bulbs etc use wifi when Powerline exists

[Dalewyn]

Powerline ethernet dumps an utterly horrifying amount of electrical noise into both the wiring and the surrounding area. Please don't use powerline unless you have no other solution.

Note: Powerline ethernet should not be confused with Power Over Ethernet which is perfectly fine.

I'm using it on two outlets after not having enough prescience to install ethernet in my wardrobe-turned-office - got any reading materials?

I have a box of old X10 devices here, one of the most reliable home automation systems I ever set up. I only switched to WiFi when my iobridge X10 controller failed and I couldnt work out the RS232 protocol for a different controller.
