Neat idea, thanks. I normally just send a ping to my slackbot but texts would probably be even better.
The idea was to make the API curl as simple and short as possible, to the point where you could probably memorize it. Would be trivial to then add additional notification targets server-side, based on user preference.
I.e. sending a Slack message -- even in the simplest form requires a rather long URL with a JSON body that has a couple of fields.
