Port used is 8899 TCP (not UDP) so you can try that. |

According to the Professional Installers Troubleshooting Guide, the AP systems ECU uses port 21 plus many ports in the range 8995-9228. In my case I was able to verify that enabling/disabling these ranges had the corresponding effect on the ECU. |

@danstowell You are correct, all ports mentioned are listeners on EMA servers so the goal of this part of the Guide is that you do not block these. If you do, data cannot be sent to EMA (and the ECU can not be updated with latest firmware for example) resulting in a internet disconnect from the ECU (lower LED on the ECU). I assume that there is an open internet connection at the remote location and the ECU is working properly there. What @puttemanp is trying to achieve is connecting to port 8899 on the ECU from a different location, therfore the firewall on the remote location must open this port to enable the integration to query the ECU. Note that 8899 is not officially supported by APsystems and therefor not mentioned. But nowadays a lot of Home Automation fans are using this port. Home Assitant alone has more than 700 active and happy users. |

I have a solar installation in my house in Portugal. My HA instance is running in Belgium.
However, I would like to add my portugal installation in Home Assistant.
When I put the converter in DMZ, I can configure it in HA (I have a fixed IP in Portugal). Dmz is not what I want, and it was just a test.
An option would be a VPN, but then I'd have to renumber my network as it has the same range of one of my other networks that is already connected by VPN.
So, I was thinking, if I know the ports that are used, I could pinhole my firewall and just open the needed ports.
