To clarify for others, that’s just for motor and AC loads. Rated capacity for resistive loads is 1800 W (15 A). Aside from a portable induction stovetop and possibly portable AC units, this is likely fine for most things people will connect to it. Its probably not a good fit for OP though.

The pine64 Pinecil is a great starter soldering iron.

I thought it needed to be connected to the internet in order to send prints to it? Does it work fine if never connected?

You’ve already received some great suggestions. Another one is Netdata. Personally, I use glances to collect the data and Home Assistant to display the dashboard. But I only do this because I already had Home Assistant running.
