README.md

This flow send a tweet if you leave or enter any self defined waypoints. You can use for this the App "owntracks" on your Smartphone.

If you leave or Enter your Office will send a Tweet with Timestamp and your Waypoint. It will not Tweet your GEO-Location.

This flow needs some MQTT Broker.
