Getting OVMS next week
by Paul Churchley 09 Jan '14

09 Jan '14

I have ordered an OVMS kit for my 2011 Mk1 Leaf and also my 2012 Vauxhall Ampera. Once I get them up and running I shall be looking to see how I might help with development. Any suggestions please? :-) I have gone with GeoSIM on both. I will need a programmer to update the firmware... can I get one in the UK? My particular interest with OVMS is interfacing to other charge station databases such as OCM. I might be able to provide a testing server too (Windows or Linux) if that might help. Paul

OVMS 101 hangout!
by Nikki Gordon-Bloomfield 08 Jan '14

08 Jan '14

Folks, We've had the responses and it seems like Saturday, January 4 is the best time and 5pm GMT is the best time for the hangout! I'm assuming those of you in different timezones are more than happy doing the required math(s) to ensure you're around at the right time! Here's my outline of the event. Please step up to the plate and 'sign up' to present different parts of the event. I'm not expecting any one person to run the 'complete' section, as I'm happy to be the host/compare. But I need to know who I'm talking with mostly in that section. *Part one: What is OVMS?* *- *One of us, I'm suggesting Mark, should do a practical overview of OVMS, what it does, and why it's needed, as well as the cars it currently works with. Ideally, some screen shots and/or live demonstrations would be good. It's also really important to tell people how it differs from OEM's telematics, and how/why people may want to use it instead of them. *Part two: How do I get OVMS?* *- Basic *walkthrough on how to get hold of OVMS kit, along with 'what you'll need' for each main car. Talk about the various websites you can visit to buy the hardware, and recommendations for SIM cards. It's important in this section to differentiate between those who want to develop/write for OVMS, and those who just want to plug in and forget. *Part three: How do I set it up? * -- This should be a walk through from downloading the iOS and/or Android apps to plugging the final setup into the car's ODBII port. Perhaps we could split this into further sections: - What will you need - How to open up the kit - How to put the SIM card in - First connection - etc etc. *Part Four: Using and understanding the app. * Since this is partly different for each vehicle, we'd benefit from having some Tesla, Twizy and Volt specific sections here. But open to thoughts. *Part Five: Questions* We can either have a formal Q&A at the end of the hangout, or we could answer them throughout. My aim is to only allow those who have already volunteered (and those who have extra stuff to add now) in on the actually video side of the hangout. Everyone else will be able to watch. If we meet on Saturday ten minutes before the hangout is due to start, this should all be possible without too many problems. I will of course, need everyone's google ID so I can invite them in. Nikki.

Model S Can Bus Specs
by Oliver Weidmann 08 Jan '14

08 Jan '14

A good new year to everyone on this mailing list. I finally found some time to play with my Model S and search for bus wires. Well here are some details: The bus connector is located underneath the touch screen (grab the storage shelf hole and pull STRAIGHT down). The connector is the same as in the Roadster. When reading the bus be sure to attach CAN HIGH, CAN LOW and CAN GROUND (you can use normal GND, see image). If you don't use CAN GROUND, the car will get confused. The Roadster doesn't care if you use CAN GROUND, but Model S seems to be a bit sensitive on this topic. Also be careful with the +12V pin. If you produce a short your instrument panel screen will eventually go black as they seem to share the same fuse (which is the 5A fuse #49 in fuse box #2). Ok, once all wires are in place and the car is still running, it's time to read some data. Bus speed is 500 Kbit/s (vs. 1Mbit/s in the Roadster). A fist quick look at the data showed me the following: ID 2C8 looks like the actual charge settings. 67 32 = min Standard 67 5A = max Standard 67 63 = one tick before max Range 27 64 = max Range Obviously the second bit bit represents the percentage of the charge settings (32h=50dec=50%, 64h=100dec=100%). It seems to be a readout only variable, as sending messages to ID 2C8 didn't change the charge settings. Maybe this is the first step for OVMS for Model S? Well, we'll have to see ;) regards Oliver --- Diese E-Mail ist frei von Viren und Malware, denn der avast! Antivirus Schutz ist aktiv. http://www.avast.com

Showing Km while unit set to miles
by Thomas Bergo 06 Jan '14

06 Jan '14

Hi, A OVMS user on the i-Miev forum in US with a i-Miev have experienced the following issue: *In the notifications, I have my units set to miles, though the Odometer reading is still in Km. Range readings are correct.* He are using the v2.5.5 FW downloaded from Mark's GitHub repository. Anyone else experienced this?

>From my experience helping people to get OVMS running, I think we should make sure the following are covered: 1) Confirming the position of the GPRS slide switch. 2) Explaining the differences between the vehicleID, 2 usernames, and 4 different passwords that need to be entered. (Bet you can't name all 4 passwords off the top of your head!) 3) Use of the OVMS provisioning web page. 4) Understanding the OVMS module's LED status blink codes. 5) Understanding the different antenna statuses on the smartphone apps. Have we identified any cars that have OVMS hardware installed but not yet provisioned, so that we can run through at least one example? Do we have the ability to show input/output from SMS on a smartphone or to stream what the smartphone app is showing? - Bennett On Wed, Jan 1, 2014 at 8:30 AM, <ovmsdev-request(a)lists.teslaclub.hk> wrote: > Send OvmsDev mailing list submissions to > ovmsdev(a)lists.teslaclub.hk > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.teslaclub.hk/mailman/listinfo/ovmsdev > or, via email, send a message with subject or body 'help' to > ovmsdev-request(a)lists.teslaclub.hk > > You can reach the person managing the list at > ovmsdev-owner(a)lists.teslaclub.hk > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of OvmsDev digest..." > > > Today's Topics: > > 1.
