First Production Batch

This first production batch is intended for experienced OVMS v2 users and v3 developers. Please note:

  • Firmware is not complete, and should be considered beta
  • Functionality is approximately equivalent to basic OVMS v2 firmware, but some advanced features (such as ACC, SMS control, etc) are not available yet
  • Firmware is far in advance of v2 in other aspects (such as built in web server, metrics, console, tcp/ip support, diagnostics, geofencing, scripting, etc)
  • Firmware can be updated either Over The Air (OTA), by Micro SD card, or over USB interface
  • Vehicle support currently includes: Kia Soul EV, Nissan Leaf, Renault Twizy, Tesla Roadster

Antenna and Vehicle Connectors

The antenna and vehicle connectors for OVMS v3 are the same as for OVMS v2, and existing cables/antennas can generally be re-used for OVMS v3. Note, however, that the frequency ranges supported by individual 3G networks may be different than 2G, so may benefit from an antenna specifically designed for the 3G frequency ranges used.

My car Chevrolet Volt - not suitable?

The first v3 firmware does

The first v3 firmware does not have support for the Volt Ampera / Chevy Volt vehicle type. So far, no developer has come forward to help porting the firmware to that vehicle. Technically, the hardware can support the vehicle - but we are an open source project and require someone with the vehicle to port the support over from v2 to v3.

We expect support for that vehicle type to come within the coming few months. As the v3 hardware is now released, this will be easier to get done.

Coupon Code missing?

When I my account and view my vehicles, I don't see any coupon codes, only a link that goes to fasttech with "search?ovms".

What am I missing?
