Add support for Tesla Powerwall

[quote=“Hodor, post:75, topic:142280”]
interestingly I have two IP addresses for my powerwall gateway, both are fixed.[/quote]
I also have two IP addresses, but one is for the LAN connection, and the other one is for the WLAN connection.

This worked fine for me. Copy the files into the newly created folder config/custom_components and restart HA. Then you can install the new integration powerwall. In the input form, enter the IP (upper field) and the password of the powerwall.

Is that true for all cases? When using the integration that came with my Home assistant image or the one suggestes by estebanp (GitHub - bdraco/powerwall: Updated powerwall integration for HASS), I had to enter the IP of my Powerwall.
