Vehicle Type: **RT**

At present, support for the Tesla Model S in OVMS is experimental and under development. This vehicle type should not be used by anyone other than those actively involved in development of support for this vehicle.

Note: regarding the Twizy, V3 works very similar to V2. All telemetry data tables and tuning profiles are fully compatible, and the commands are very similar. Therefore, the basic descriptions and background info from the V2 manual are valid for V3 as well.

The V2 FAQ can be found here:

https://dexters-web.de/faq/en (english)
https://dexters-web.de/faq (german)

All latest V2 document versions can be found here:

* V3 commands need to be in lower case.
* When accessing via USB terminal, first issue enable (login).
* V3 commands are similar to V2 commands, just structured slightly different.
* Try help”, “?” and xrt ?. Twizy commands are subcommands of "xrt".

The Twizy recuperation levels are very low by default, regenerative braking is so weak it doesn‘t need to trigger the brake light – so a regen braking indication has been omitted by Renault. The Twizy can be tuned to one pedal driving though with high neutral braking power.

The SEVCON normally can generate a regen braking signal itself. That signal can be configured using the xrt cfg brakelight tuning command. Pin 11 on the SEVCON main connector will go to GND on activation. The problem is, that pin is not connected on the Twizy, using it needs modification of the connector. To my knowledge this hasn‘t been done successfully up to now, so we don‘t even know if the Twizy SEVCON firmware includes that functionality.

9. Do a test: plug in the OVMS (Note: the relay switches on during the first OVMS boot), switch on the Twizy, issue commands:

* *egpio output 1 1 should activate the brakelight*
* *egpio output 1 0 should deactivate the brakelight*
* ``egpio output 1 1`` should activate the brakelight
* ``egpio output 1 0`` should deactivate the brakelight
* Note: if you‘re using another EGPIO port, use the according port number (3-9) instead

10. Mount the glovebox and you‘re done.
