OVMS logo

We need to change the OVMS logo, to better reflect the vehicle independence. The existing logo is too much Tesla. Felix has kindly prepared a couple of options for us, attached below. My preference is for the one with the car outline (even though it retains a hint of Tesla), as it emphasizes the vehicle comms aspect. This is quite urgent, as the Teslive people are pushing for artwork. What do you guys/gals think? Regards, Mark

Actually, on that topic (almost) - we should discuss how OVMS users might checkin (or even auto-checkin) to OCM. That would help us track which locations people are using and the quality of their experience there. Are there any recent thoughts on this from the OVMS side? Currently there are no third party apps writing to the OCM API. Doing so currently requires at least authentication (via the web UI) - this is also the method used by the OCM mobile apps. There is the possibility of a quicker/simple login to OCM via third party apps by way of a security code emailed to the user (who would either be new to OCM or an existing user). Not massively secure (there are holes in the approach) but it would make it easy for third party apps to quickly authenticate. Alternatively we can provide URLs which OVMS users would open in a browser/webview which go on to use the standard mobile app or site. This is the easiest for OVMS apps to implement. Depends on what integration people would like to see?

Apologies for lack of progress - rather hectic at work, but over lunch I did a quick rebuild of ovms having noticed a little typo I introduced when adding the suggestion from Mark and Tom With the fix battery level is now correctly reported. This is my fully charged 2012 leaf (at around 246 GIDS +/- a few :-( OVMS Nissan Leaf XXXX XXX:Not charging SOC: 88% Ideal Range: 117 km 3:00 PM LEAFDD pictures included This is great news as it gives me confidence the unit/sw is working. -- ---- Nigel Jones

PICkit changes parameters (EEPROM)
by Michael Balzer 01 Jun '14

01 Jun '14

Hi all, my PICkit2 frequently alters single EEPROM cells on flashing. It's set to "preserve EEPROM" and mostly does so, the effect only for example changes the server parameter from "64..." to "S4...". Other parameter slots also have been affected, my last flash changed my registered phone id, and a forum member reports a change of the first vehicle id byte from "D" to "R". Is there a way to make the flashing process reliably preserve the EEPROM? Thanks, Michael -- Michael Balzer * Paradestr. 8 * D-42107 Wuppertal Fon 0202 / 272 2201 * Handy 0176 / 206 989 26

Twizy : Symptomes of a failing charger
by Julien (JaXX) Banchet 30 May '14

30 May '14

Hello, And an extra hello to Twizy Specialists. I'm running into what's believed to be a common Twizy issue concerning the onboard charger Since a big week: during charge, after a few minutes (and for sure if I come back to the car while it's ending charge) the SERV light is on, along with the exclamation point battery icon. Upon departure, the SERV is off, but comes back after a few seconds before going away after 3/4km of driving. From what I read, it's the forthcoming signs of a failing battery charger (hopefully, warranty ends in 3 weeks). Though, most of the people who had this usually noticed a missing fan noise, which I believe I still hear. This does not seem linked to the pretty impressive accident I had a few weeks ago (only plastics involved at first sight, gotta plan the budget for repairs until police enquiry+insurance kick in) So, unless I'm totally nuts, I've ever only seen flatline pwr_curr rates (then decreasing approaching topping off). Simply, I wanted to share with you odd power curves from a charger giving it's last breath: https://www.dropbox.com/s/nmbavtx0r2bku4p/twizy_charge_pblm.png [ Arrived early at work nearly (expected) depleted battery (9%), from 8:40 to 9:17: steady 2400 +/- 50 W, then it drops to 1040W at 9:30, before slowly coming back to 1700W at 9:44 then 1550W since... ] Though I've had the SERV on the last charges, since this morninh, a Stats? command shows Charging, Topping Off, even though the time I walk to the office it didn't get to 11% of SoC, and the ETA, at 8:44 seemed consistent at 199 minutes (now 10:31: ETA Full: 105 minutes, SoC 60%)... odd. "Voilà" That's about it... Gotta call the garage now :-/ Hugs and all! JaXX./.

H2O Wireless
by Tom Saxton 26 May '14

I just posted info on using a cheap OVMS-compatible cell service reseller, H20 Wireless, on TMC. http://www.teslamotorsclub.com/showthread.php/7716-OVMS-Installation?p=6668 97&viewfull=1#post666897 Hat tip to Cathy for doing the research to find a cheaper provider for us. It looks promising, but the jury is still out. Tom

Sorry Paul, I was encapsulating myself in a black box. Either way, OCM can facilitate the API as required by OVMS.

GEVCU 5 hardware
by Kevin Sharpe 19 May '14

19 May '14

Version 5 of the Generalised Electric Vehicle Control Unit (GEVCU) will include BT, WiFi, and isolated I/O in a low cost and rugged automotive enclosure. Many of the things on my OVMS wish list! GEVCU development is progressing well and I¹ve suggested they add GPS as an option in the final version; https://groups.google.com/forum/#!forum/gevcu-development Would their be any interest in porting OVMS to the GEVCU hardware? Or even in merging the projects possibly? I ask this because the more resources we can bring to the project the more likely it is to flourish.
