I use these for all sorts of things. The heavy duty ones are better as they are suitable for appliances and not just lighting. You can also get them Alexa (or whatever your preference) voice controlled and they work well.
You can control appliances individually or all together.

I've used them extensively for a few years to operate lights or to turn on the Festool vac in my temporary workshop. I only ever programme them for off and on (ie I don't use the differentiated numbers), and I am using a decent brand. Never had the slightest inkling of a failure - but I am a sample of one.
Do you have any links?

I'd be interested in links to evidence of failures of these too.
I use several of them: three in the lounge controlling lights/TV, one connected to an oil-filled radiator in the garage so I can turn the heating on remotely and one with the vacuum cleaner plugged in that I use with my home-made cordless power tool vacuum cleaner starter (note to self: must come up with a shorter name for that thing!).
I tend to turn off the vacuum cleaner at it's own switch when I'm leaving the garage, but the radiator one stays plugged in all the time and has done for about 10 years now I think. It's thermostatically controlled, so probably not the end of the world (apart from expense) if it turned on of its own accord, but I'd certainly rather it didn't! As far as I know it has never happened.
It'd be interesting to know if any confirmed failures were explained (i.e. was it down to an inherent fault or did a next-door neighbour happen to have the same remote control!).

It’s down to the probability of a burst of rfi/ noise matching the switching code. The ones that I have only use 32 bits and there is no return confirmation link.

I acknowledge your expertise in this area but, surely, the same model having the same fault with two people suggests to me that perhaps there could be some inherent design faults in some of these switches that make them more susceptible ?
