Both features mentioned here (ongoing cron job style tasks, and easier 3rd party control of the FarmBot) are good ideas that we would like to implement eventually; they are just lower on the priority list because they are not as “core” of a feature in comparison to something like looping and variables.
In ways, 3rd party control is already possible though. See the Telegram integration @mdingena developed, and the Amazon Alexa skill that @kimptoc has been working on.
