Non dimmable switches

Hi All,
I am just begining to plan my home automation [my] world domination plan, namely for when RPi’s ar eback in stock (later this year according to RPi themselves).

I am struggling to find non-dimmable light switches, (basic and 3 pole) that don’t need a ground wire (older house).

Same goes for plug sockets (single and double) but ive not looked for these extensively yet. Lights are my main target atm.

In case in changes anything I am UK based.

Thanks in advance for any help you can give.

I would check out sonoff products, they might be helpful.
