Smart ED question
by Mark Webb-Johnson 28 Oct '19

28 Oct '19

There is a question that came in to support, regarding Smart ED. Can someone with experience of that car have a look, and help answer? https://www.openvehicles.com/node/2335 <https://www.openvehicles.com/node/2335> Battery display in the App I have the smart ED 451. It has a 18 KWh battery and charges very slowly with max 3,7 KW. The display of the battery In the OVMS app is not quite right. - In the green to the left it says 8 KWh. I assume this is the used power from full. So it should be on the other side, as the green area with 70% represents around 13 KWh of power remaining. However, the numbers don’t add up. - to recharge fully I will need over 1 hr. But the app only estimates 16 mins. How can I change that? Thanks, Mark.

Kona electric and http routing
by Peter Lord 27 Oct '19

27 Oct '19

Hi All, I've been lurking here for a while still debating wether to ditch my autopi in favour of OVMS. One thing thats held me back is to find a way to use the wifi hotspot as a NAT router - this is useful to allow my sat nav to get traffic and charging point updates. As far as I can see on the web page this isn't currently supported. However I did see a couple of projects that adds NAT support to lwip : https://github.com/martin-ger/lwip_nat_arduino https://github.com/jonask1337/esp-lwip Does anyone know if adding NAT has a fighting chance ? Cheers, Pete

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

Change to v2 server - client specific commands
by Mark Webb-Johnson 26 Oct '19

26 Oct '19

I made a change to the ovms v2 server code (remember, the repository moved) and added support for client specific commands. Previously, if an App sent a command to the car, the reply from the car is transmitted to all connected Apps. The change is to try to keep track (a queue) of outstanding commands and who sent them - then when the reply comes in we direct it to the specific App that sent the original command (and not the others). If the queue messes up, and we lose track, we revert to the old behaviour. It seems to work well, but was non-trivial. In particular, the command functions 1 and 3 (feature and parameter lists) complicate things as they have multiple replies to a single command - so specific support had to be added for those. It is live on the api.openvehicles.com <http://api.openvehicles.com/> server now. Hopefully there won’t be any issues, but please let me know if you see any issues running commands - send me the vehicle ID and time, and I can check. Regards, Mark.

http client calls from script
by Anko Hanse 25 Oct '19

25 Oct '19

Hi all, I was wondering if the OVMS scripting support already includes some kind of http -client. I would like to be able to do something like this: function stopCharging() { var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { var resp = JSON.parse(xhttp.responseText); var status = resp.response.status; print('status: ' + status); } }; xhttp.open("POST", "https://<url to charge box manufacturer>/<my deviceId>/stop-charge", true); xhttp.setRequestHeader('Authorization', '<some magic token>'); xhttp.send( '<some magic json struct>'); } I've got a proof-of-concept javascript running on my pc, including some preparation http calls to get the right magic token and the charge-box indeed receives the command and stops charging. But am now having trouble translating this in javascript that is accepted by the OVMS module... I also have the beginning of a OVMS script, triggered by ticker.60, that basically does: var charging = OvmsMetrics.Value("v.c.charging"); var bat_soc = OvmsMetrics.AsFloat("xnl.v.b.soc.instrument"); if (charging === "yes" && bat_soc >= 80) { stopCharging(); // <-- this still fails... // Note: OvmsVehicle.StopCharge(); is not possible on Nissan Leaf (only StartCharge is) } It would be really nice if I could get the OVMS module to trigger the stop charging command by itself. That would give me similar functionaliy as what this guy did using a CarLoop device (https://www.mynissanleaf.com/viewtopic.php?t=23741) If it is not possible, then I need to revert to running a script somewhere on a server, that will periodically keep an eye on the OVMS metrics and then triggers the stop. OKidoki, Anko

GIT reorganisation - v2 server code

24 Oct '19

I’ve moved the v2 server code to its own repository: https://github.com/openvehicles/Open-Vehicle-Server.git <https://github.com/openvehicles/Open-Vehicle-Server.git> This will provide a better structure, moving forward. Regards, Mark.

Re: [Ovmsdev] OvmsDev Digest, Vol 93, Issue 26

That's good to hear, you power readings were very similar to mine. I pessimistically rounded up when the values were fluctuating. Where would be the best place to publish these readings in the documentation? Prior to measuring the power readings myself I tried to search for OVMS power consumption in the docs but could not find any results. How about adding a new section to readthedocs called "technical specs"?
