I’ve got my ESP32 communicating in RealDash and can see triggers in the CAN monitor, but I’m failing on mapping to items like turn signals, fuel level etc. can anyone please advise.
You need to write a CAN description XML file. That file describes to RealDash how your values are arranged in CAN frame data. See documentation here:
