I’m not getting any results with Fusions code, even with the provided examples.
Your code works great, I have no idea what I am doing, so my idea is adapt the NSW RFS python example to the Vic GeoJSON file, run it as a daemon in a docker container and somehow output each valid entry into HA as a map point via MQTT or the API(if that is even possible, more research required) and have it run every 5 or 10mins(whatever the min the API allows)
edit: looks like this:
would suit to be adapted for the Vic Emergency file and your geojson feed, so I’ll give that a whirl.
