Hi,
I am trying to get the Goodwe non-HACS integration to work through a firewall into a different network.
The Goodwe Inverter is on one network while Home Assistant is on another. An additional Raspberry Pi has interfaces in both networks.
Now I don´t get the port forwarding to work. I understood that the inverter is called on UDP port 8899 (sometimes 48899). This port is is opened with a firehol / iptables rule
dnat4 to 172.16.2.122 proto udp dport 8899
The usual pyhthon test script works from the RPi itself but not from any machine on the seperate network.
I did try UDP broadcast forwarding but it never gets triggered by any packet.
Reading through many posts about the Goodwe protocol I never understood how the communication back is supposed to work. Can somebody help me?
