I'm happy to announce, I'm taking orders now for the next batch of tattlers. I expect to ship the first 10-20 this month and the remainder in November. USA and Canada only for now. The Tattler is not an iPhone or Android app. It's hardware, a small Linux box with a cellular modem. It is connected to the roadster diagnostic connector. It uses simple SMS text messages for status and control and should work with any SMS (text message) capable phone. The tattler can be user installed behind the passenger seat or professionally installed underneath the driver door jam. Price: $499 + s/h I would prefer to pre-activate the tattler on AT&T or T-Mobile so I can confirm that everything is working properly. The following plans are available from the carriers: AT&T $25 Activation $20 unlimited SMS $10 1000SMS/mo $5 200SMS/mo T-Mobile $10 Activation $15 unlimited SMS T-mobile $10 1000 SMS/mo T-mobile Here are some of the supported features: An installation video can be found here: http://youtu.be/0kZcToGwvZA The command structure is designed to be simple and SMS/T9 friendly. E.g. "charge stop" and "stop charge" are the same. Attached below are pictures from the various commands. Commands are in green, car responses are in gray.

You can use your Verizon/Sprint phone to control the tatter. But, No the tattler modem must be activated on GSM network (AT&T or T-Mobile). I am working on porting the Gobi API (linux) to the tattler, but Verizon/Sprint support will have to come at a later date... Sorry. Yes. If you send me your SIM card, I will install it and confirm it works with the tattler. Disclaimer: This device sends and receives CAN messages on the CAN0 bus using the diagnostic connector of the Tesla Roadster. Because it uses the same diagnostic connector as the Tesla service technicians, you should shutdown and disconnect your tattler before bringing it in for service.

The Tattler is the result of my own analysis of my 2008 & 2011 roadsters and discussions with (and CAN data from) other owners.
