System Start/Stop in Pocket

[pierrei]

Thanks for putting this project together - it's one of the coolest things I've seen in a while!

I'd love to be able to start/stop the automatic process control from my pocket computer. A first step could be as easy as just add the start/stop button to the pocket computer without showing any statuses. Next step could be to display the status of the system as well. This can for sure be extended to display the error that scrammed the system and also allow for a ack and a reset, but that can come later.

Would be so amazing to be able to start stop while walking around checking things!
