A couple of years ago I was planning to get the OVMS module for my Roadster 1.5, and discovered that I’d waited too long and the v1 hardware was discontinued because the v2 hardware was in development. So I had to wait until the v2 hardware came out. Then I got my Model S and forgot about it for a while. I’ve got used to the remote monitoring my Model S has, and decided it’s time I got the same for my Roadster. Now I come back again to look at getting the OVMS for my Roadster 1.5, I find it all quite confusing. The Tesla Motors Club forum has a thread on OVMS with 605 posts in it — hardly a quick reference for what I need to do. When I go to http://www.openvehicles.com/ I find lots of stuff you’d expect to see at an open source repository, but no Quick-Start guide. There’s a link to the Roadster User Guide, which is great, but doesn’t tell me what to buy or where to get it. I notice that the OVMS v2 box appears to have a connector marked “GPS”. The Roadster User Guide talks about installation and positioning of GSM Antenna but makes no mention at all of a GPS Antenna, not even a comment to the effect, “Ignore this; you don’t need it.” Do I need it? It took me a while to realize that the FastTech link on the left of the page is not just just an advertising link from a sponsor, but is actually where you get the hardware. So, I’m getting closer, but... the FastTech product page lists not just the OVMS Car Module v2 but a bunch of other stuff too, that I may or may not need to get: GPS Antenna: SMA GSM Antenna OBD-II OVMS Cable: Left OBD-II OVMS Cable: Right OVMS Tesla Roadster Cable PICKIT 2 Compatible Programmer PICKIT 3.5 Compatible Programmer Which of these do I need to get? I’m thinking “no” to the GPS Antenna (it uses the Roadster’s GPS, right?) and “yes” to the GSM Antenna. I’m thinking “no” to the two OBD-II OVMS Cables and “yes” to the OVMS Tesla Roadster Cable (which is ironically not available — I hope that’s just a temporary situation). Do I need the PICKIT 2? PICKIT 3.5? What's the difference? Do I need both? Neither? If someone could post a quick OVMS shopping list for Roadster 1.5, that would be a huge help to me and people like me looking to install this in our Roadsters.
