A Node-RED node to decrypt encrypted OwnTracks location messages and to add the msg.location field to the on going message so it can be used with things like the geofence node or the mapping output.
To install globally:
npm install -g node-red-contrib-owntracks
To install for just the current user
cd ~/.node-red npm install node-red-contrib-owntracks
Connect a MQTT input node to the input side, enter the shared secret in the setting dialog and decrypted messages will be sent to the output.
