exactly…POR cars need help from RD.
RD is able to handle data simply car manufacturers don’t make it easy. Especially since it varies per model not just manufacturer. Asking real dash to sit down and decipher each one is a lot of work.

either find a specialist who can read the canbus data ans decipher the PID so you can make a custom XML.

go hardwire. There are products where you can tap into the wires behind the cluster to read the voltage from as use that for inputs.

Hardwire…can you point me in the right direction here for products?
thanks
Contact onegauge they’d be able to explain it better for you. I tried talking to them during COVID but stuff came up and I’ve just stuck with OBD2 atm.

PIDs are not necessarily used over canbus. There are ID’s that are used on canbus but if someone hasn’t mapped out the ID’s and values, it will require some reverse engineering to determine what the values are. An example of this would be to tap into the canbus of the car with a canbus sniffer and start the stream and turn on the left blinker and watch the data. There are some videos on YouTube that might be able to help in narrowing down what ID is for what. You will need to learn how bits and bytes would work together in the CAN stream. Many times, simple on/off devices will be a single bit. If the left turn signal is bit 3 in the stream that would be 00000000 where the 3rd 0 is showing that the left turn is off. If it’s on, it would be 00100000. Now this might be that it is set to 1 and stays at 1 when the stalk is moved, or it might change from 1 to 0 to 1 as the light actually blinks.
I don’t think that a Porsche Macan of that age would be using any type of encryption on the bus.
