Hi

I have reached my level of understanding. I believe I need a funcion to do this task, but I have no idea how to write it. Could someone please help with the below?

My Flow

NB: There may be a lot simpler way to achieve this…

I have an app on my phone GPSlogger (Android)

I am trying to compare its GPS location with Node Red Geofence Locations.

Below is the Full msg I can see. I would like to extract the GSP Data to compare it to the Inside or Outside geofence locations.

Thanks

Hans

What has this to do with home assistant? I suggest you ask on a node-red forum.

No worries, thought this was a good place as it was the Node Red sub forum and I was using it within Home Assistant.
