Incorporating NodeMCU ESP8266 senders

[SCarns]

Thanks for sharing afinite.

If I understand your notes correctly, you are using the ESP8266’s 33 volt connection to measure resistance across the tank level sender, but you tanks are NO LONGER hooked up you your boats 12 volt battery system?

Mine are connected to 12 volt analog gauges, so I am having trouble figuring that out, but I never considered disconnecting them and “going directly to an ESP or even straight to the Pi.

Thanks for the lesson. I’m still looking at my options.
