So in order to save... what? £10 of electricity, I have to throw out and replace a perfectly good dimmer switch? Per room?
Seems a bit wasteful.

How many tonnes of coal is it worth burning to keep your dimmer switches?

How many tonnes of coal does it take to make a dimmer switch to replace one that I'm being forced to throw out long before the end of it's lifespan?

it's a bit like how people tend to gloss over that manufacturing just the battery for an electric car releases 18 tonnes of CO2
or basically 5 years emissions of a driving a normal petrol sedan

Several years ago now,
but I had one “friend” on Facebook proudly saying they had driven an electric car all the way from Sussex to Scotland.
At that time the energy mix of the UK generation capacity was approximately 40% coal. Which I reckon got them as far as Nottingham.

Your figure is a bit high there, chuppy
The quickest of Googling shows that you're wrong about the CO2 by about 30% and you've more than doubled the time taken to balance the CO2 cost of the WHOLE car compared to a petrol-burner.

I don't think my housemate/landlord has yet realised that his plan to replace all of the house's lamps with 'smart' bulbs is going to cost him more than just buying replacement lamps
since the existing mains dimmer switches won't work with them and normal light switches don't really work well with them either (since you need to leave the power to the lamps turned on in order to remotely control them). Not particularly smart, in my opinion...

I have a few wifi smart bulbs - look good to begin with, then once the novelty wears off, they're pretty boring.
I wouldn't want to make all my lights dependent on a single point of failure eg wifi hub or zigbee bridge - I can see that ending in some loud sweary words at some point
