Hi all,

I've been happily running an MPGuino for years, and apart from resetting "current" when I EoC for some reason, it's been rock solid.

In the modern world of Home Assistant and ESP32s, I was wondering of anyone had tried sending MPGuino data to their smart home dashboard?

I see plenty of folk doing that with an ESP32 and elm327, but I don't have OBD II

Additionally, if I wanted to see fuel level, I'd probably have to work out a way to tap the fuel level sender resistance signal. Maybe sensing the voltage on that line?
