Locations and scripts
by ovms 03 Dec '19

03 Dec '19

Hi I would like to run scripts based on location. The scripts work fine, but the location service stops working. I guess the location service requires CAN1 to be working? Since CAN1 stops receiving after a short period of time, the location service also stops. Is there a way to bypass this so the location service does not depend on CAN1 working? Kind regards, Stein Arne Sordal

Android app updated, lost my car
by Greg D. 25 Nov '19

Last night the Android app updated on my phone. I'm still getting alerts from the car, but the only car shown on the app is the "Demonstration car", which of course, isn't active. I've added the car back, and it seems to be working. So, just FYI. Greg

Added Pushover and SSL client support
by Marko Juhanne 26 Oct '19

26 Oct '19

Hello all, I've been wanting to have a bit more configurable notification system on my mobile phone compared to the OVMS mobile app (quiet hours, different message priority levels, override quiet hours with emergency priority, custom sounds, persistent notifications demanding acknowledgment etc). I already use Pushover as notification platform for my home automation system and it has worked nicely for these two past years so I decided to port Pushover client to OVMS as well. For those who don't know, Pushover is a notification platform that has apps for iOS and Android. They also have a desktop (actually web) application as well. You create an account and then register your application. There's a 5 USD per platform one-time fee, which I find quite reasonable. Message limit is 7500 messages / month / application. So if you have multiple cars, you could register them as individual applications. I'm not affiliated with the company, just a happy customer. There are now commits for Pushover support on my fork ( https://github.com/mjuhanne/Open-Vehicle-Monitoring-System-3) It's up to date with the main branch, and has the SWCAN commits as well. I would appreciate if others could test it before making a pull request, since there are now quite many changes. I didn't want to add another http client, so I used Mongoose. But then after enabling SSL support using mbedssl I found out that there's this client space "struct mg_connect_opts" that will be too small (and causes crash) if MG_ENABLE_SSL is not enabled also in every component that uses Mongoose. To configure Pushover, there's a new Config/Notifications page on OVMS. You can filter which notifications and events will be relayed and select their priority levels accordingly. I thought about using web config pluging, but maybe we could integrate this page to configure notifications for OVMS mobile apps as well? Best regards, Marko Juhanne

SWCAN and enhanced Ampera/Volt support
by Marko Juhanne 18 Oct '19

18 Oct '19

Hi all, I've been tinkering with OVMS and Opel Ampera these few past months, and the I've made some progress with the SWCAN support. As you know, the SN65 transceiver cannot do High-Voltage Wake Up, so many of the nice-to-have polling and remote controlling functions are not available on those cars that rely on it, such as Volt/Ampera. So I've created an add-on SWCAN board that attaches to the internal OVMS extension header. The board uses TH8056 transceiver, which is specifically designed for SWCAN bus. As for the controller, same MCP2515 is used as in OVMS. Here's the link to the boards GitHub page: https://github.com/mjuhanne/OVMS-SWCAN For the firmware patches, here's my OVMS branch: https://github.com/mjuhanne/Open-Vehicle-Monitoring-System-3 There are a lot of changes, especially MCP2515 code add-ons and refactoring, of which some are specific to the new swcan-bus, but some could be beneficial otherwise as well. Then there's the support for the new board and TH8056. On the other hand, if a car can be woken up without HV WakeUp, the board is not really needed and the SN65 can be used with 33.3 kbps speed to communicate on SWCAN bus. Since ESP32 supports only 3 hardware CS on one SPI bus and all the CS lines are now already used, there's also patches for software CS (that's what the additional MCP2515 is using). With my OBD cable I wire SWCAN to use CAN2 lines and put the 2nd MCP2515 on OVMS to sleep, but there's no reason why all the 4 CAN controllers couldn't work independently at the same time (untested at this time). There's also patches to the Ampera/Volt module code base to include SWCAN support, add handling of several new CAN messages (still work in progress, more to come!), as well as VoltStar-like capabilities (locking/unlocking doors, remote preheat) similar to Brian Batista's MyVolStar app/OBDLink MX-combo. Sadly, I haven't been able to get the VoltStar-specific functionality to work on my 2014 Ampera, but other non-Voltstar SWCAN messages do work (waking up the car, controlling windows etc.). This is is similar to other reports of MyVolStar on 2014 Volt/Ampera, so maybe something has changed in the ECU behaviour between MY13 and MY14. It would be really nice to get other OVMS developers with SWCAN/GMLAN enabled cars to test these. SWCAN specific patches can be tested also without the board, but naturally the HV Wakeup functionality is not available. Let me know if you're interested so I can send a PCB or two for testing (I have bunch of leftovers). Best regards, Marko

Time for 3.2.003?
by Mark Webb-Johnson 26 Sep '19

I think it is well past time for a 3.2.003 release. Things seems table in edge (although some things only partially implemented). Anything people want to include at the last minute, or can we go ahead and build? Regards, Mark.

40kwh leaf
by Glyn Hudson 23 Sep '19

23 Sep '19

Hi guys, In a couple of weeks time I will have on lone for a week a 40kwh 2018 leaf. I briefly tested ovms on the 40kwh leaf a while back but no metrics seems to be supported. I'll do my best in this time to try and figure out what's different between the older and newer model of the leaf to work towards adding support. Does anyone know if the 40kwh leaf CAN frames has been decoded? If so is this documented anywhere? There must be some major changes since not even a single metric seemed to work when I tested briefly. What would be the most useful data I could capture during my time with the new leaf? It would be great to be able to add ovms support the new leaf. - sent from my mobile device

GPS and GSM
by Mark Webb-Johnson 20 Sep '19

20 Sep '19

Normally this would indicate a problem with GPS tracking. In this case, the car equipped with OVMS is in a container, on a ship, heading to Australia. Just lost contact as it headed out of cellphone coverage range. It will be interesting to see how many times it pops up, as the hologram cellular roaming kicks in whenever it passes close enough to a coastline to pickup a signal.
