ECU-R Pro and wired LAN

[c0mplex1]

Because the 2.4GHz band is crowded here, I decided to use a LAN cable to communicate with the ECU-R Pro. The LAN port of the ECU-R Pro is directly connected to a PoE switch (or injector). On the ECU-R Pro side there is a PoE adapter to separate data and power and everything works fine.

The advantage of a wired connection, in this way, is that you can place the ECU-R Pro far away from the wireless access point, in a remote place and/or very close to the inverters. So, you don't need a WiFi connection or separate power outlet anymore.

TL;DR:
You do not need a WiFi connection at all to communicate with the ECU-R Pro.

Thanks Frank, I changed the documentation for this finding.
