Coming to think of it, at some point I may have implemented a single button wake (like the article) by creating a JuiceSSH profile to run my WOL bash function then exit as a snippet, and then making an Android widget on the homescreen to connect with that profile.

I have something like that as a termux shortcut and it works nicely ( https://wiki.termux.com/wiki/Termux:Widget ). Pretty simple, too; just stick the ssh one-liner in a script in ~/.shortcuts/ and it works.
