I was so tempted once I bought a house to set up everything to be smart, but in the UK I've found it hard to find smart switches that fit in our wall easily (most are 35-45mm and most older houses in the UK are brick walls).

I've considered smart bulbs but someone will always turn off the light switch and then nothing is smart.

I guess since then I've realised that I kind of like simple electric switches and regular LED bulbs.
