12v battery voltage sensor for Home Assistant?

[ElGuano]

I'm running the HACS Rivian integration on HA, and don't see anything that reports on 12v battery, other than the normal-operation/fault indicator.

I'd really like to see when and how often the vehicle wakes from sleep to top off the 12v battery. Is there a way to do this?

You can monitor the sleep/wake cycle already but the only way to get a true picture is to get a wifi battery monitor. Easy enough to build yourself...

Oh nice, ty!

From the video, it supports two separate WiFi networks too, which presumably means one can be at home, and one can be the hotspot from the truck itself, which may be helpful when in camp mode or anywhere away from home.
