A lot of modern irons also have motion sensors built into the handle. Allowing it to cooldown or even turn off when it detects no activity, and automatically heat back up when it does.

The TS100 custom firmware, https://github.com/Ralim/ts100 https://github.com/Ralim/ts100 , also has features like detecting incoming voltage for use on lithium battery packs to prevent overdischarge. Pine64 even mentions they've sent a prototype to this developer.
