also, you could use an extra pin to get the incoming voltage to everything and use that

if the Halmet reads voltage at the analogue pins, without consuming current, then with your schematic as is you could 'assume' the incoming voltage is 14.4, measure the resistance of the gauge and use the "VoltageDividerR2" transform to solve for R2. see my code from line 209-220 - https://github.com/Techstyleuk/sensesp-engine_monitor/blob/main/main.cpp

no, it is not correct to assume Vin is 12V. for a lead acid system the battery is likely to be 14.4V when the engine is running (most of the time when you are looking at engine temp), but that depends on the alternator. A INA219 is designed to check for voltage drop across a resistor to make a current monitor. therefore it has 2 voltage sensors which you can attach to either side of the gauge. the Gauge is R1, buy a cheap multimeter (if you don't have one) and use it in resistance mode, check the resistance between the two terminals. define that as R1.

Thanks, is there a circuit diagram to go with it?

I am not sure about Hamlet, but the Pi and ESP32 stuff i have done means setting up a voltage divider and connecting a 3.3v pin through a known R1 and then a sense pin, before the sensor. this works well but does not allow you to keep a 12v gauge because of the pin max voltage.

Do you want to maintain the VDO gauges or replace them?

in the definition of PGN127505:
* Fluid Level contains an instance number, type of fluid, level of fluid, and
* tank capacity. For example the fluid instance may be the level of fuel in a
* tank or the level of water in the bilge. Used primarily by display or
* instrumentation devices.
I copied this from "N2kMessages.h" (https://github.com/ttlappalainen/NMEA2000/blob/master/src/N2kMessages.h) but believe it is a direct copy of the NMEA2000 standard. This is what I used in my code. There seems to be some Halmet specifics for alarm inputs (line 272 of main.cpp) but you should be able to send out a 127505 message and then have you MFD see this as bilge high and alarm

it uses PGN127505 and sets grey water fluid level to full when the float switch is activated

I have a NMEA 2000 battery Monitor that could be used as an example and has a bilge monitor that uses a float switch to set bilge to 0 or 1 and transmit that out? see: https://github.com/Techstyleuk/SensESP-NMEA2000-Battery-Monitor/tree/main it is in SensESP ver 2.0 so some bits would need to be changed but shouldn't change the NMEA2000 stuff.

MattNJ - so, im using a few 1wire temp sensors.
I found it quite finicky, at least on SensESP 2.0, but you can copy and paste them out but do them top one first and then delete the rest. save and restart, then continue with the second one...... otherwise disconnect them and reset and then add thm in order
