You may want to look into Shelly relays. You wire them to the physical switch in the wall and can control them locally with Home Assistant or just individually via WiFi. Only downside for most folks (especially in the US it seems) is that they generally require a neutral wire to work.

It is probably way too late for that to make any difference, no?
Slander?! I resent that. In print its libel.
Yeah, no. He almost entirely verbatim copied the text and wording on the original article and shuffled some words around to try and make it less obvious (and failed). It is blatant plagiarism, there is no other way to call it. This was no innocent mistake of forgetting to list a source. Watch the hbomberguy video segment about it, it paints a very clear picture.
I am in central Europe and I have both the AirGradient One and the AirQ Basic. The AirQ is much more capable, with more sensors (especially a dedicated VOCs sensor), and has a better design, and the Home Assistant integration works really well locally. It is quite expensive though.
The AirGradient One took a long time to ship (almost three months, but that was expected and communicated clearly by the AirGradient folks) but it definitely is available for shipping to Europe, so probably also the UK. It has fewer sensors but you can (and I did) flash it and customise it with Esphome. Look for the github repos of user MallocArray. So it also works very well locally, using the esphome integration.
So it really depends on what you want to measure. If it is just Co2 and pm2.5 then the AirGradient is probably enough and much cheaper. With the AirQ you pay a lot more but you get many more sensors.
The Home Assistant blog covered the whole thing very well: https://www.home-assistant.io/blog/2023/11/06/removal-of-myq-integration/
