Hello, I have the C8, any recommendations for a 12v battery monitor that would work good with the Hubitat c8?
I did find this with a quick search, but it looks like a do-it-yourself product that makes no claims of Hubitat integration.

Also this from the Home Assistant community:

Maybe one or both of these can point you in a helpful direction.
The Shelly Plus Uni will monitor a 12V battery and it integrates with HE. I'm not sure if the built in driver supports voltage monitoring but there is a community driver that does.
I've had pretty good luck with the device connected to my ASUS routers. Others have had issues with it staying connected to some WiFi networks.
It can be a PIA to set up as it comes with very little documentation but the community is a great resource.

Seems like any 12V monitor that comes with an app uses Bluetooth, so Hubitat is out for those. However, do you happen to run HA? Looks like there is an integration for HA for the BM2 device, that could probably be brought into Hubitat with HADB.
Look here. D.C. Voltage detection, any Zigbee or Z-Wave devices report voltage?
+1 for the Shelley Plus Uni. I've been using the previous version Shelley Uni to monitor my backup sump 12 v battery for several years. Note that it is powered from that same battery.
