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).

If you have relevant containers (e.g. the *arr stack) then you can bring all of them up with a single docker compose command (or pull fresh versions etc.). If everything is in a single file then you have to manually pull/start/stop each container or else you have to do it to everything at once.
