I have a Paperwhite 2015 version that I got back in 2016 for only $30 when they had a big sale on them to unload for their new version. Looks like on eBay that 2015 version goes for $30-50 today.
I transfer books to it via a USB using Calibre. It doesn’t need nor do I connect it to WiFi. Newer models might also be able to work via USB only, I don’t know, but I know my 2015 works that way.
Some dashboards can do this, check out homepage as one example. Glances is a great tool if you want to create your own. Really you should not rely on checking status pages for health but instead set up monitoring and notifications.
I use healthchecks.io and smtp_to_telegram to be instantly notified of SMART failures, storage limits, backup and other script failures, and if docker services go down. As with all selfhosting though, there are plenty of other options for both the monitoring system and the notification system.
