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?
