Edwin, welcome :-) https://docs.google.com/spreadsheets/d/1sY5n8WFu52U6a4_mg3MdcGcmDk3scAP8_muS... There really seem to be quite some similarities, e.g. the battery capacity is read from PID 41A3 for both Volt & Bolt, and the SOC is available at PID 8334 on both. So it's probably worth giving the Volt adaption a try and using that as the template. Looking at the most current polling vehicle addition (Hyundai Ioniq vFL) may also be worth while, as that demonstrates the current recommendations on handling poll responses etc.

In the bolt/ampera pid sheet there are these pids but how do I translate these into a new car template?

That's pretty straight forward: * The column "ModeAndPID" includes the combination of the request type (aka mode, mostly 22) and the actual PID. * Column "Header" is the address of the ECU to query for that PID. The response address is that value + 8 if not specified explicitly. * The "Equation" needs to be implemented by the poll reply handler. Example: for the SOC, fetching 228334 from ECU 7E4 translates to this polling list entry:     { 0x7e4, 0x7ec, VEHICLE_POLL_TYPE_OBDIIEXTENDED, 0x8334, {  0, 10,   10 },  0, ISOTP_STD }, // SOC …because VEHICLE_POLL_TYPE_OBDIIEXTENDED = 22 (you could also use VEHICLE_POLL_TYPE_READDATA or write 0x22 if you like). The timing { 0, 10, 10 } means no polling in state 0, polling every 10 seconds in poll states 1 & 2. State 3 is unused. You use the poll states to model different poll frequencies per vehicle state (e.g. off / driving / charging). In PID equations, "A" refers to the first payload byte, "B" to the second and so on. For single frame responses, the poll reply handler can simply read directly from the "data" byte array. So A*100/255 translates to: data[0] * 100.0f / 255.0f Regards, Michael Am 16.04.21 um 10:10 schrieb Alexander K:

Hello Edwin

The most similar car to Bolt/Ampera-e is Chevrolet Volt. Try a Volt vehicle with your car or use it as a template. You will most likely need a swcan module to wake up the car.

Hello All,

I'm currently driving a 2018 Opel Ampera-e and since Opel pulled out the plug from OnStar as they moved to PSA group (peugeot) my car is offline. Recently I noticed the OVMS project and bought myself a kit. It's hooked up and connected but only location data is available at the moment.

The pids needed are available from this location https://allev.info/boltpids/ <https://allev.info/boltpids/> Jason_ABRP wrote some tips in the forum thread https://www.openvehicles.com/node/2345 <https://www.openvehicles.com/node/2345>

As I am not a developer but a eager to learn system engineer in IT i'm lost from this point. In the bolt/ampera pid sheet there are these pids but how do I translate these into a new car template? My son is a software developer student and can also help me in making this template.

Any help would be appreciated.

Thanks,

Edwin
