I have been using InkyPi for my own E-ink display. It recently got support for weather as well. I'm using a different display though, so your mileage may vary, but for me it works like a charm, would highly recommend. :)
> you can sign up to each service with a unique email address, e.g. <microsoft>@<your-domain.com>, which makes it easy to see if any services ever sold your address
You don't need your own domain for that. Gmail (and probably the other big ones) support it as well, just add a plus sign and whatever after your username: username+microsoft@gmail.com will end up in the inbox of username@gmail.com.
Looks really nice! Anyone know of an equivalence for Intel iGPUs? Would love one for my plex server. I'm currently using intel_gpu_top, but is nowhere near this level of detail, unfortunately.
edit: Just realized it does indeed support Intel as well, according to its github page. Neat! Will give it a go for sure!
