Haproxy and sunpower

I was able to get my Raspberry Pi in my Sunpower PSV6 box and install Haproxy on it.

I can communicate with the pi. I have power cycled the solar coms breaker, as well as the system, since confirming that the pi is in “PVS6 LAN1” following the https://starreveld.com/PVS6%20Access%20and%20API.pdf.

I still can not seem to be able to communicate with the PVS6 or able to pull it into Home Assistant.

What version of the Raspberry Pi OS are you running? I’m just in the middle of setting this up for my PVS6 but I’m running Bookworm on my Pi Zero W and step 3 in the Networking section says :

edit /etc/dhcpd.conf , add two lines to it, and save

however there is no such file on my system. there is a file:

/etc/dhcp/dhclient.conf

but its not clear whether the changes needed would be the same as in those instructions…
