If you can get IKEA where you are the INSPELNING line has Zigbee smart plugs with energy monitoring for only like $12. I believe they have a UK variant as well.

I’ll second PurelyMail. Easy to set up and they have explainers for all the various settings. I pay $10 a year for “unlimited” domains and mailboxes (some caveats but for minimal mail we won’t hit any limits).

Stacher is a great GUI for yt-dlp on Windows and MacOS.
