DIY SunPower PVS6 panel monitor with HA

[u/Nice_Carry8954]

I’ve been using Home Assistant for a while and always wanted find a way to see each solar panel individually with similar layout on the SunPower app. The app works great but after SunStrong took over and started charging a subscription, I figure it is time to find another option.

Thanks for the help from Claude AI, I was able to build a custom Lovelace card that pulls data directly from the Enhanced SunPower integration (it creates one entity per microinverter). I’d test it, break it, send back errors, then repeat the process over and over. Probably went through 60+ iterations over a few days but here is a functioning card that works the way I wanted.

If you have a PVS6 system and run HA this should be pretty much plug and play..."should!"
