Model S REST API

[rdrcrmatt]

Has anyone ever seen battery_heater_on = true in the charge state response?

I am querying through many days worth of data including times I know I saw a battery heater notification on the dashboard and I see nothing.

Is there a verified way of knowing that the battery heater is actually on? I am trying to see if some of my vampire drain is from battery heating and/or 12V battery charging.

This was leaving my GF's house Sunday morning at 10:48am.

Has anyone ever seen battery_heater_on = true in the charge state response?

My logs have battery_heater_on since at least car_version=1.33.44, but only with values of null and false. And, yes, I've seen the battery heating message. Curious.

It seems to me like the HTTP Long Poll interval in the streaming API is now ~5 minutes, where before it was ~2 minutes. Can anyone else confirm that?

This might turn out to be a good thing because I can start a poll and use it to monitor if the car is in motion, or parked for up to 5 minutes, without generating any additional requests that would keep the car awake.

 

[jayman]

Hey Hans. I don't know if this is helpful but my car had never slept until I stopped the service running the streaming app. I know it's supposed to let it sleep but it has never worked on mine and I'm using the most recent 0.8.5. Have you noticed this with anyone else?

Where you running with the --zzz flag to enable sleep mode? If not, it will keep the car awake all the time as you saw.

 

[jayman]

I have been using -zzz flag...

Sounds like I need to update... crap.

It would be great to see the REST interfaces support charge scheduling. I sometimes find I want to change my schedule but either am away from car or would prefer not to walk out and get in to change it.

 

[kseitzberg]

Great to hear - I am actually working on a scheduler that I will incorporate into TeslaMS. It will support up to 10 scheduled commands in the GUI.

The commands that will be available are:
Start/stop charging
Set charging to Max/Standard or given percentage
Start/stop HVAC - and set temp to x (In celsius)
Alert if unplugged at time of check.

Also considering whether i should implement a feature to enable an alert if vehicle is unplugged/charging stops if charge state less than X

GUI will be similar to the one found in VisibleTesla.

If one should need further schedules these can be manually entered in the MongoDB behind teslams - and thus unlimited.

It will be possible to schedule a command each 5 minutes.

Hope that others than me will like the feature.

Sounds interesting. Looking forward to it.

Getting data out of mongo

I have been using vb.net to get data out of mongo. However, I notice that it doesn't always get the most recent data especially when the car had been sleeping. After I drive for a while I am able to retrieve my location at a 3 sec. interval from the database. I guess my question is, how is the data put in to the database because I know all the data is there when I check tesla tracker? Is there a difference in how the data is dumped into the database soon after sleeping? Thanks.

This is likely just like VisibleTesla. When the car is sleeping the app queries less frequently. When you start on a trip it is still waiting for the next query time. When it finally queries next time you have already driven for some distance.

 

[jayman]

That makes sense but when I use the "tesla tracker" app it has tracked my entire trip so it appears all the data went into the database. Not only that, I couldn't query the database for like 20 min after I left...

Who's going to TMC Connect?

Anyone planning to attend TMC Connect this summer? Is there interest in getting together to talk about what we're all doing with the REST API?

Good idea. I plan to be there to heckle... I mean participate as an audience member.

Ha, yeah, wouldn't that be nice. Think it's going to be a while before an SDK sees the light of day.

I don't chant much, but I'd chant for this

My sentiments exactly.

I have had success with the REST interfaces. However, when calling the streaming interface I am receiving a 401 Unauthorized error return. Here is an example code snippet:

var options =
            {
                url: "[URL]https://streaming.vn.teslamotors.com/stream/[/URL]" + vehicleId + "/?values=speed,odometer,soc,elevation,est_heading,est_lat,est_lng,power,shift_state,range,est_range",
                responseType: "json",
                type: "GET",
                user: username,
                password: token
            };
       // the error function is always called with 401 result
       WinJS.xhr(options).done();

Any insights appreciated. I pass in the first token received as token. Probably something simple but I am not seeing it.
