By subscribing to an mqtt topic on a broker where http://owntracks.org/ clients publish messages the message is then routed to pushover.net (see here for the additional node https://github.com/christoface/node-red-nodes/tree/master/social)
The flow includes testing inject nodes and debug nodes.
edit: Slightly updated to respect the changes introduced in recent Owntracks releases. ( >= 0.5.20 on Android )
