Firmware release 3.3.005
by Michael Balzer 26 Jul '25

26 Jul '25

Everyone, I'd say release 3.3.005 is due. 3.3.004 was 03/2024, we've since collected quite some fixes and new features, including extensions for Smart EQ & the new MG4 support. There are lots of new Smart users now, as Mercedes have stopped support for the official Smart EQ App (see https://www.smart-emotion.de/article/415-mercedes-discontinues-smart-eq-app…) The current state is also very stable, I had no issue reports. Any objections / open fixes or additions that should be included in 3.3.005? Regards, Michael -- Michael Balzer * Am Rahmen 5 * D-58313 Herdecke Fon 02330 9104094 * Handy 0176 20698926

How I got sphinx working on ubuntu 23.1 + WSL
by Michael Geddes 26 May '25

26 May '25

Firstly, thanks to Michael Balzer for fixing my errors in the rst files I checked in. (Also, apparently I can't spell Auxiliary - doh). I _had_ tried to get sphinx working recently and failed miserably, so I tried again this morning. The problem is that ubuntu: * Doesn't provide a package for m2r2 or sphinx-mdinclude (a fork of m2r2) * No longer allows you to pip install into the main python library path So first I got rid of the installed sphinx-doc sudo apt remove sphinx-doc Then I set up a sphinx virtual environment pipx install sphinx pipx inject sphinx sphinx_rtd_theme docutils mistune requests sphinx-mdinclude For some reason I was getting run-time python errors with m2r2 which is why I tried switching to mdinclude. In docs/source/conf.py I changed extensions = [ 'm2r2' ] to be 'sphinx_mdinclude' instead of 'm2r2' The pipx command creates a virtual execution environment for sphinx and puts a shim for sphinx in your local path that runs it in the virtual environment. //.ichael

Integration of Simcom 7670 and changes to Simcom Powering
by Info Zeitnitz 07 Apr '25

07 Apr '25

Dear all, I finished to integrate the Simcom 7670 modem into the OVMS code. See https://github.com/zbchristian/Open-Vehicle-Monitoring-System-3.git branch update_cellular. Modem Powering =============== I had problems to get the 7670 working with the current code. The modem was stuck in a power cycle loop. I checked the Simcom documentation for the 4 models 5360, 7000 series, 7600, 7670 and the powering procedure via the PWRKEY pin is the same, but with different on/off timing. Depending on the hardware, the PWRKEY can be inverted as well. This is the case for my Lilygo TCall board, but I think not for the OVMS HW versions. At least version 3.1 connects the corresponding MAX7317 pin directly to the modem. Assuming, that all hardware versions use the PWRKEY procedure for powering, I streamlined the code and moved the corresponding functions into separate files (simcom_powering.cpp and simcom_powering.h). This avoids the duplication of the code. All this leads to substantial changes in ovms_cellular and ovms_cellular_modem_driver as well. The code works now perfectly for the 7670, but testing is required for all other models. If my assumptions about the OVMS HW versions are not correct, or the modems do not work as documented, some modifications might be needed. GNSS Location ============ The 7670 no longer accepts the currently used AT commands to obtain the location as a GRMC sentence. So, I added code to the new 7670 class to request the location via the AT+CGNSSINFO command. Since this has to be send explicitly again and again, I implemented a corresponding call in the StatusPoller of the 7670. All the NMEA related code has been adapted to handle the corresponding CGNSSINFO response. In conclusion, before doing a pull request, it would make sense that the code is tested with the other hardware and modem models. So, tell me what you think and if the general strategy of the mods make sense to you. Best regards Christian

Another incident
by Chris Box 05 Apr '25

05 Apr '25

Hi, It's happened again. Yesterday while driving the Leaf lost drive mode, forcing pulling over. I couldn't reengage gear until I had disconnected the 12v battery. Looking at the evidence today, the incident can't be explained by writing random bytes in CommandWakeup(), nor by having the wrong timing. It actually suggests that OVMS locked up ten minutes before the car was impacted. Here's what happened. 13:15 to 13:17 I drove off from home, but forgot an item so quickly returned back there. The sd log records this activity just fine, and the last entries before the suspected hang were these: 2025-02-07 13:19:59.174 GMT D (93751944) events: Signal(vehicle.asleep) 2025-02-07 13:22:29.184 GMT I (93901954) housekeeping: 2025-02-07 13:22:28 GMT (RAM: 8b=79028-81980 32b=12560 SPI=3262992-3285432) There should have been the next housekeeping message at 13:27:29 but none was recorded on the sd. Log flushes are configured to occur after 30 seconds. The last MQTT metric update my server received was around 13:27:50. This showed it was connected to home wifi. At 13:28 I unlocked the car, started it and drove off without noticing anything unusual. None of this activity appears in the log. During the drive there should have been a connection via Hologram to my server, but none was received. Ten minutes later at 13:38 I was driving when a yellow warning light came on and the car moved to neutral. Essentially the same symptoms as in January: turning off and on would not clear the fault; it couldn't detect brake status meaning it told me to press brake pedal when I already was. Also showed I-key system error. As I was stranded I used the only option I knew of to clear the fault, and I disconnected the 12v battery. On restoring power and dismissing the fault notice, it was happy to drive. The log shows this cold start SNTP was at 13:44. On returning home, unfortunately 'boot status' says nothing about a crash, presumably because any information was lost when I pulled power. So it seems there is some mechanism by which OVMS can lock up, without watchdog oversight. And that ten minutes later it can do something that becomes a critical issue for the car systems.

SDCard speeds.
by Michael Geddes 24 Mar '25

24 Mar '25

I while ago I was talking about issues with my SDCard, and I've just had a friend have some similar issues. Both these issues were fixed with setting the max frequency to 15MHz config set sdcard maxfreq.khz 15000 This does end up making things a bit slower, but at least it works. The reported max of my card is 25Mhz. I'm concerned that the default is misbehaving. Is this a software issue? or is it a hardware issue? //.ichael

Leaf AZE1 (2018+) Integrations
by Wayne Love 19 Mar '25

19 Mar '25

Greetings all, I'm new here and with OVMS but have a fair amount of experience messing around with OVMS. I've been working on extending the Leaf code to support the AZE1 model (production year 2018 onwards) and have it mostly working. If anyone is interested, I've forked the code and created a branch here wayne-love/Open-Vehicle-Monitoring-System-3 at Leaf-AZE1 My first question, are there any considerations / checks that I need to do before submitting a pull request? Thanks Wayne

Simple Auth for api
by Chris van der Meijden 18 Mar '25

18 Mar '25

I'm trying to connect our e-UP to EVCC using the http api. This fails, because I don't have a Drupal server installed. I only found AuhDrupal and AuthNone as modules for the the server. I don't want to install a Drupal instance for only one user, so I'm now trying to write a AuthSimple module for only one user with the username and password included in the code (I know, unsecure), so that the authentication for that user goes through and I get the variables I need for EVCC. Before I reinvent the wheel, does a code snippet perhaps exists, that does the trick? Regards Chris
