Port forwarding needed to track phone?

Yea… stupid sorry… To much focused on my own solution. Lol

So easy thing about this setup is that you can have your internal Pi/HA with low protection (easy or non passwords etc)?

Yea i know, english is not my native language.

hmm this stuf is pretty new for me. So if i understand correct:
1 Machine for example a Raspberry Pi, with 2 mosquitto processes running, wich you bridge on the same machine to talk? Then 1 of the 2 mosquitto’s is portforwarded to talk to outside my lan (owntracks etc), and the other one is connected to my HA?

Correct me if im wrong please!
