I broke that a few months ago (this new module meant I had to reorganise some low-level crypto stuff to make room), and am glad it is fixed again.</div><div><br></div><div>For the SOC, I'm really just guessing. Supposedly message 0x5b3 on car can bus has GIDs in B6bit0 and B7 - I just divided that by 3 to get a rough approximation of SOC, but it is obviously not working. I think this one shouldn't be too hard, but I don't have any CAN bus dumps of what the 0x5b3 message looks like. If I can see a dump, with matching known SOC / GIDs, then I am sure we can get this right. That said, active polling (which is what leafspy uses) seems to be a better way of getting this, as it gets us true GIDs off the EV can bus.</div><div><br></div><div>Glad about the parking indicator. I work off the parking brake for that one, and it is an important status flag for quite a few things.</div><div><br></div><div>I'm working on the polling mechanism at the moment. It is very similar to the OBDII VIN number polling mechanism we already have, and my recent work on the common vehicle.{h,c} polling code should make this relatively easy.</div><div><br></div><div>Regards, Mark.</div><div><br><div><div>On 18 Dec, 2013, at 6:22 am, Nikki Gordon-Bloomfield <<a href="mailto:nikki@aminorjourney.com" target="_blank" mailid="nikki%40aminorjourney.com" subj="">nikki@aminorjourney.com</a>> wrote:</div><br><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">So here’s what I’ve learned from the alpha code so far… <div><br></div><div>1) It’s recording the parking status accurately, as far as I can tell. within a few minutes of parking, it’s noting that on the app screen. </div><div><br></div><div>2) It’s certainly sending me alerts as you might expect for low SOC warnings. </div><div><br></div><div>3) But sadly SOC isn’t working correctly with my car. For some reason, SOC is jumping all over the shop, with 22% SOC seemingly a favourite place for the OVMS code.

What did appear to happen is that SOC dropped and then went back up again. I had values from 27% SOC down to 14% SOC to Empty and back up to 22% SOC. I’d guesstimate my real SOC was nearer 45%.

This is a problem I believe with the LEAF CAN bus, which turns itself off when parked. I’m guessing we’ll need to figure out a way to wake up CAN and then switch back off again?
