So the final answer for now that I am using with my wife is Owntracks, plaintext with encrypted payload to my own MQTT broker. There’s no storage of location. Later I may enable TLS on mosquito and not encrypt the payload as I have some ideas I want to have a python client for another purpose and there’s python modules that support TLS but I would have to implement the matching libsodium to decrypt the payload from Owntracks and that seems like more work as well as TLS is the “right” way to do it anyway.
