Engine monitor

Thanks for your reply. SensESP came up in my search but does not seem to be on sale neither to use existing sensors. Anyhow definitely seems to do exactly what I'm looking for.

SensESP is a Signal K sensor development library for ESP8266 and ESP32. It can be used as a high-level toolkit for creating ESP-based hardware sensoring devices that interface with Signal K servers. In practical terms, you can use it to create temperature or engine RPM sensors, tank level sensors, anchor chain counters, satellite compasses, bilge level alarms, or smart light controllers for your boat.

I'm looking for a more "easy" approach, where I read data from the existing sensors. Found a post from years back with no real answer/solution, https://www.raspberrypi.org/forums/viewt...p?p=743246

I had to replace the LCD display engine hours and I'm convinced there is an open alternative, https://www.marinepartseurope.com/en/vol...-2486.aspx
There is even a extra panel available to duplicate display, https://www.marinepartseurope.com/en/vol...0-278.aspx
The electric schema does not help much, https://www.manualslib.com/manual/102986...=43#manual
I can code, but I am no (very little) electronic knowledge.

Thanks
