I set up something like that using gpscon. Unfortunately it seems starting gpscon is not enough to actually activate the location services.
But for reference, this is what I use to submit location data to PhoneTrack (a Nextcloud app). Itās very crude and does more than @Seven.of.nine wants here, but maybe itās useful.
All the magic is done by gpscon, so play around with that.
I manually trigger start of this service from Situation when it detects i am āNot At Homeā, i.e. not in range of known Wifi networks:
