These days you can control the charge direction from Android, that may work. On my phone, I can also use Acc (and AccA) to limit charge current/voltage, and possibly stop charging (I have to check whether it cuts the connection). Advanced charging controller requires root, though.
Seedbox access without exposing it to the wider web.
Managing personal devices.
One day I had to go to the office and only then did I notice my keepass hadn't synced in months. My home PC was sleeping so I SSH'd to my Openwrt box, got the MAC for my PC and used etherwake to start it. From there I used RDP to login and get an updated password. All from my phone.
