My Latest video is now live:
You will see I now have a Heads Up Display (HUD) fitted to my car, so this is how i did it.
OVMS has a built in OBD spoofing protocol (obd2ecu) specially designed for connecting up a HUD. This takes the data OVMS already has from the car and provides it in a friendly way to the OBD HUD. In my case I am taking the temperature queries from the HUD and feeding back the SoC from the car…pretty neat.

The HUD I am using is this:
UPDATE: The cable needed is now stocked by @glynhudson at: https://shop.openenergymonitor.com/ovms-v3-hud-obd-ii-f-cable/
( This will come a lot faster to the UK than the linked one from fast-tech)
You simply set it up as per the guide, you can even have it switch on/off with the car. (Note: I also have it switch off with the 12v not charging as Zombie mode override can look like the car is “on” according to OVMS)
