OVMS Server GCM/FCM migration
by Michael Balzer 14 Apr '24

14 Apr '24

Everyone running an own server instance, I've just merged the FCM development branch into "master" for the server. There were issues with occasionally frozen child processes with the initial standard fork scheme under heavy load. Thanks to a hint by Mark, I could rework the message delivery to use AnyEvent::Util's fork_call, which has been running rock steady for a week now on my production server. See the README section on Android push notifications if you haven't done the migration yet. Keep in mind, the old API will be disabled on June 20.

Using ovms to reboot my firewall
by Craig Leres 10 Apr '24

10 Apr '24

I recently set up my "dev" ovms module to give me a method to power cycle my home firewall and I thought I would share with the list. Originally I was using a pfsense SG-1100. This particular version uses a problematic emmc flash memory for the system filesystem. These are not very robust. After years of flawless operation I started having trouble with lockups. This made me search for an out-of-band method to power cycle it. Remembering that I had some of the prototype ovms pcb's Mark made (and some DB26 connectors) I decided to use a solid state relay to interrupt the power to the firewall (via the ovms cellular network connection). By this point I had replaced the SG-1100 with a SG-2100 that I got from a buddy (with a nice M.2 slot replacing the emmc). It has a locking power connector and I was able to find compatible switchcraft inline parts. Using a type B solid state relay (normally closed) power is not interrupted when the ovms module is rebooted. Here's the script: vfs cat /sd/scripts/pfsense-cycle egpio output 9 0 sleep 5 egpio output 9 1 To run it I paste: script run /sd/scripts/pfsense-cycle into the iphone ovms app. I've attached a couple of pictures.

FIAT e-Doblo (same as Peugeot Rifter, Opel Combo, Citroen Berlingo?)
by Raphael Mack 03 Apr '24

03 Apr '24

Hi, I own a eDoblo from Fiat and recently bought an OVMS. Very cool.project, thanks for all.the effort you all have put in it! Beside trouble to permanently plug in the generic ODB2 connector due to space below the cover I face the fact that it is not supported by OVMS. So I created https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/976 and would like to contribute. In my former life I worked in automotive industry but I already recognized that it is much easier to read a CAN trace if you have a DBC and the well known Vector tools at hand 😃. In case anyone has some hints where I can get more info about the frames and signals, even from other cars in the same family (EMP2, Peugeot e208, e2008, Opel mokka-e) from the Stellantis brands or former PSA it could be a great help to sort at least some ID into the 'interesting' or 'boring' boxes. Last but not least any idea where I could get an overall bus architecture for the car from would be cool, as I would like to install the the OVMS in a permanent place different from the ODB2 connector. Looking forward to a great journey here. BTW: initially I had trouble receiving mails from the list, as the sending servers IP was on some blacklist and therefore blocked on my incoming mailserver. So if you could put me personally on CC on an answer I'd be happy, just in case this is not yet sorted out. Regards, Rapha

V2 server not starting
by Derek Caudwell 25 Mar '24

25 Mar '24

Hi all, My ovms unit is regularly disconnecting from the V2 server with the message: State: Waiting for network connectivity Server is ready to start I'm on 3.3.003-696-g562479ea, I suspect it is happening when I either leave home or return (simple script turns on/off modem to use wifi). The V3 server does not have the same issue. Any ideas on debugging appreciated, as the network/wifi connection is up and stable? Also I finally got to the bottom of my issue with the 7600 modem, the daughter board's RX pin was not long enough causing intermittent connection to the main board. Cheers Derek

Firmware release 3.3.004
by Michael Balzer 17 Mar '24

17 Mar '24

Mark & everyone, there are new feature extensions in the pull request queue, i.e. poller timing control by Michael Geddes & a new MG5 model variant by Peter Grey. I'd rather close 3.3.003 now and release the current state as main 3.3.004 before merging new features that again would need testing. A new main release is overdue, and the latest fixes by Michael Geddes did improve stability significantly. I haven't had a single crash with 3.3.003-621 yet. Objections? Regards, Michael -- Michael Balzer * Helkenberger Weg 9 * D-58256 Ennepetal Fon 02333 / 833 5735 * Handy 0176 / 206 989 26

Support for Kia EV6?
by Douglas Urner 15 Mar '24

15 Mar '24

Is the Ioniq code close enough to the EV6 to allow reading the battery condition? I have a friend with an EV6 that won’t charge to full capacity. We’re suspicious that there is one or more bad cells, but so far the Kia dealer hasn’t been willing / able to tell her anything more than “we don’t find any problems”… Other suggestions for how to read the battery pack would also be most welcome. Thanks, Doug

Forum Notifications
by Mark Webb-Johnson 05 Mar '24

05 Mar '24

I’ve had to turn off email notifications for forum (and other such) posts. It was a useful feature, but despite running new user verification emails, captchas, and stopforumspam lookups, we keep getting spammers polluting the forums and that gets us repeatedly blacklisted by the over-zealous Spamhaus. So, email notifications are off for the foreseeable future. The forums see little traffic anyway, and we need a better approach (perhaps also for this mailing list). Discord? Google groups? Any ideas of something open and friendly? Regards, Mark.
