More AddTrust/UserTrust CA certificate trouble
by Stephen Casner 12 Dec '20

12 Dec '20

I've just moved to a different laptop which caused me to look at some things I have not looked at for a while. One of them was the perl script Tom Saxton gave me to query the openvehicles server to gather the log entries for my car. That script references: https://www.openvehicles.com:6869 This is now failing to log in. Testing manually with curl gives: auge14> curl -X GET -c ovms-cookie "https:/www.openvehicles.com:6869/api/cookie?username=xxxx&password=xxxx" curl: (60) SSL certificate problem: certificate has expired More details here: https://curl.haxx.se/docs/sslcerts.html curl failed to verify the legitimacy of the server and therefore could not establish a secure connection to it. To learn more about this situation and how to fix it, please visit the web page mentioned above. This looks like it could be related to the AddTrust CA cert expiration that occurred back in May. I check the macOS keychain and I see that the new USERTrust RSA CA certificate is already there and matches the one that Mark included with his email to this list about the problem. Looking on the web for guidance I found the following suggested command which appear to indicate that the server is still using a certificate referencing the old CA cert? auge15> openssl s_client -showcerts -servername www.openvehicles.com -connect www.openvehicles.com:443 > cacert.pem depth=3 C = SE, O = AddTrust AB, OU = AddTrust External TTP Network, CN = AddTrust External CA Root verify error:num=10:certificate has expired notAfter=May 30 10:48:38 2020 GMT Is this something that needs to be fixed on the server, or is there something I need to change in my query? -- Steve

Charging Monitor Plugin
by jaunius＠gmx.com 09 Dec '20

09 Dec '20

Hi, I created this Plugin as I was not getting the necessary details in one screen from the app. Maybe something to look in to for the joint iOS/Android app. https://github.com/mjkapkan/OVMS-Plugins/tree/master/chargemon See print-screens attached. It is still in beta but fairly usable. Will finalise and add all my plugins soon to the main repo. Stay safe, Jaunius Sent using the GMX mail app

Do I have to flash "entire chip" with esptool if I already have the code on my OVMS box?
by Steve Davies 05 Dec '20

05 Dec '20

Hi Mark et-al, I've installed the esp32 and the esp-idf environments on my Mac and successfully build the OVMS firmware. In the developer guide it then covers how to flash the box with esptool. But: do I need to do that? - my OVMS box is up and running already - I'm guessing I can use OTA update to update with steve@maximus OVMS.V3 % ls -l build/ovms3.bin -rw-r--r-- 1 steve staff 2986336 Dec 5 12:24 build/ovms3.bin ? Since the "flash from web" and and "flash from file" are looking for an ovms.bin. Nervous to brick my box since it was expensive to get it to Cape Town. By the way, my build prints 'App "ovms3" version: 3.2.015-162-g10232c58-dirty' I recognise the git commit hash, but what is the "-dirty"? (I build a "bmwi3" branch of a fork of the original project - maybe that answers my own question?) My OVMS box currently says it's running "3.2.015/ota_0/main (build idf v3.3.2-881-g22d636b7b Sep 2 2020 08:32:35)" Thanks, Steve

Hello from a new subscriber
by Steve Davies 01 Dec '20

01 Dec '20

Hi, I'm Stephen Davies. Mark suggested that I say hello on the list, so: "Hi!". I own a 2019 BMW I3S BEV and I'm keen to try to add support into OVMS. (I live in Cape Town in South Africa - the i3 is the one very few EVs sold here) I've done a fair amount of work reverse-engineering messages from a couple of apps that can already talk to the I3 on OBD2 port. So I have a fair list of PIDs from that. My OVMS box arrived the other day. I built an ovms-server and I've got my OVMS box talking to my server and through to the IOS OVMS app. So the next step will be to set up to be able to build the firmware from source and then to start adding the i3... Can I ask one question in conclusion: how do I get the OVMS IOS app to do a TLS connection? I told it to use port 6870 but it does not do a TLS handshake. Do OVMS devs hang out in an IRC room, Slack or some such? Thanks, Steve

DBC primer
by Michael Balzer 01 Dec '20

01 Dec '20

Everyone, I'm in contact to a guy who would like to add support for the Renault Kangoo ZE. He's no developer, but has managed to collect quite some info on the Kangoo's CAN / OBD2 communication. The Kangoo has lots of live data frames, and partially even works with the Zoe module. I told him he can define a DBC file, but saw we didn't have any documentation on this approach yet. So I've written a small primer: https://docs.openvehicles.com/en/latest/components/vehicle_dbc/docs/dbc-pri… But I haven't used DBC myself except for writing this primer now, so if someone has more experience, I'd appreciate a second look. An example on how to trigger and decode OBD2 reads would also be nice, but I think he'll manage without for now. Regards, Michael -- Michael Balzer * Helkenberger Weg 9 * D-58256 Ennepetal Fon 02333 / 833 5735 * Handy 0176 / 206 989 26

ELM327 codes to
by Soko 27 Nov '20

27 Nov '20

Heya, Another thing I can't figure out at the moment. I have to poll the VWeUp and I figured out (hopefully) how to do that. But I have no clue how to translate the "usual" ELM327 Header+PID to one entry for the OvmsVehicle::poll_pid_t The only value I've understood is the polltime. On my OBD2 interfaces I use a PID of 0x22028C for SoC. But PID is here only 16 bit! Where do I put the header 7E5? What is txmoduleid and rxmoduleid? I can't believe that I'm the first one with this issue ;) Couldn't find any doc though :( So I'm very thankful for any pointing in the correct direction/doc/example. thanks Soko

OVMS on Apple Silicon Mac
by Mark Webb-Johnson 23 Nov '20

Here’s OVMS iOS App running on an Apple Silicon MacBook Air. Installs and runs like an iPad App, either in a window or full screen. Notifications come in nicely, and preference settings in Open Vehicles / Preferences menu. Works well, with zero changes. Regards, Mark

Travis CI
by Chris 18 Nov '20

18 Nov '20

Hi, Google couldn't find anything in the archives. Due to my failure to test a build before a pull request I was thinking of adding a Travis CI build file to ensure pull requests actually compile. Is there a reason this hasn't already been done? Is this something that you'd be interested in? Thanks, Chris.
