I was very careful not to accept their magnanimous offer of an extended warranty, and I even explained why in great detail when they called me to express their "concern" that I hadn't yet accepted. Basically, the only reason I've ever had to call for service for my on-the-Blink EVSE is to fix problems caused entirely by their buggy control computer. My contract has now expired, so the unit is completely mine. In fact it stopped calling home back in mid-January, before my contract was even over.
I am a Linux and networking geek. With just a little effort I could probably reverse engineer the whole thing -- but why? I simply can't think of a single useful thing to do with it. Fer chrissakes, an EVSE is just a glorified extension cord. Why do I need it to run Linux when all I want is a reliable way to charge my car, and its only real function is to inhibit that charging?
The next time I get a pink screen of death or have any other problem charging, I'm going in there and disconnecting Hal's higher brain circuits. (I see I'm not the only one to have devised that metaphor.) Maybe it would be worth hacking the thing just so it can sing "Daisy" in a slower and slower voice as I disconnect the Linux board's control and power lines. That should make a good Youtube video.
I really like Linux, but there are appropriate and inappropiate uses of any technology, and this was one of the inappropriate ones.
Here are some of my Livejournal blog entries saying what I think of Ecotality and their technology:http://ka9q.livejournal.com/7340.htmlhttp://ka9q.livejournal.com/7961.html
