    (possibly also fixes issue #387)
  New/updated commands:

  This includes crashes and firmware updates

- Tesla Model S support for Baolong TPMS

For full detail on all changes, check the GitHub revision history. The v3 modules can be updated over the air (wifi), via SD CARD, or over USB - all without requiring special hardware programmers like the PICKIT used for v2. The simplest way to update the module firmware is to connect it as a client to your wifi network (or phone hotspot), and then use the web interface Config / Firmware / Flash-from-Web; that will show you the version you are running, as well as the latest version available for update. One click on 'Flash now' and the update will be downloaded and installed. Alternatively, you can download the firmware update to a file named ovms3.bin in the root directory of a FAT formatted SD CARD and insert the card into the module's slot - the new firmware will be updated automatically and the file renamed ovms3.done to signify completion. This firmware also includes the feature to check for and automatically update to newly available firmware, every night (so long as the vehicle is connected to WiFi). After updating to 3.1.005 or later, you can enable this for future firmware releases with 'config ota auto yes'.

You can choose the release level by setting 'config ota tag edge | eap | main', as one of:

  • edge: Bleeding edge developer nightly-builds
  • eap: Early Access Program (full releases, but with little public testing)
  • main: Publicly tested full releases (the most stable)

Thank you to all the open source developers who have contributed to this, and previous, releases, and thank you for your support of the project.
