I am using the OwnTracks app on Graphene OS via http and it’s working well so far, but I only set it up very recently.
I installed with obtanium and it doesn’t need any play services, Graphene’s location service works fine.
I am using a different back end though, GeoPulse not Reitti. Still evaluating the different choices, I will probably try Reitti as well.

You can get data via HTTP into reitti. Registering reitti on a MQTT broker also works.
