Now that Doug_G and TomSax are handling the log parser effort, I wanted to share my next effort...
The Tesla Tattler! (Thanks to Peggy Jones for the name)
This is the fourth generation of my tesla monitoring system.
V1 ran on a HP netbook with Verizon WWAN card attached to talk to a web server to post updates.
V2 was never really stable due to a bug in the linux pl2303 driver.
V3 ran on a china clone of a Keil MCB1768 + USB GPRS modem.
V4 (this version) runs on "off the shelf" ARM9 hardware. It uses phone SMS text messages for control.
Design constraints:
Based on the above constraints, the hardware must be "off the shelf" (at a higher cost). It must include a GSM modem because the Roadster 1.5 does not have one. Due to the small market, it is not feasible to develop an app for each phone type. Therefore, the UI must be based on SMS text messages. T-Mobile has a $15/mo unlimited SMS plan. To keep the SW development tool costs down, it will be Linux based.
Tattler hardware:
Linux ARM processor w/CAN controller, 2GB SD card, +12 pwr supply. GPRS GSM modem. Includes a cable that plugs into the Roadster Diag connector. The Tattler can be self installed behind the passenger seat headrest or professionally installed inside the driver side door jam.
Price: $499
Expected shipping date, September 2011
Here are some of the supported features:
The command structure is designed to be simple and SMS/T9 friendly. E.g. "charge stop", "stop charge", and "stop" are the same.
Attached below are pictures from the various commands. Commands are in green, car responses are in grey. (this is not an iPhone app, it works on any phone that can send text messages).
Disclaimer: This device sends and receives CAN messages on the tesla CAN0 bus. I don't work for tesla, nor have any friends that do. I'm just passionate about Tesla's products and understanding how they work. The Tattler is the result of my own analysis of my 2008 roadster and discussions with (and CAN data from) other owners. Ideally, I belive I've written the tattler code so that it could be integrated in to the existing VMS Linux applications and make use of the internal GSM modem in the roadster 2.x

V4 (this version) runs on "off the shelf" ARM9 hardware. It uses phone SMS text messages for control.
Design constraints:
- Must work on all cell phones (not just iPhone or android)
- Small market -- only +1500 tesla world wide. With 10% attach rate, that's only 150 users.
- Cost target < $500.
- Must work with both 1.5 and 2.x roadsters.
- Should be easy to use.

Yes. It should work with any SMS text capable phone.Will your app work on a Palm Pre Plus?
