Using moitessier hat and GPIO

[PaddyB]

So a solution like this http://signalk.org/2019/08/20/sensors-part-2.html except that the you use esp32 instead of the esp8266?

Something like that. The esp32 is quite a powerful device though needs some power when transmitting wifi, not that hard to do with a decent size buck power supply.
It's actually very cheap these days to get PCBs made by jlcpcb.com, I'm looking at getting some more boards made up with voltage,current, barometer, temperature sensors - will share the link here.
