OVMS Module and Cooldown

[dpeilow]

I've tried SMSing the ACC STAT, ACC PARAMS? and ACC ENABLE commands to the car and it does nothing. I just see it as a text message push alert in the OVMS app. It's coming from the registered phone and other commands like STAT work fine.

What am I missing please?

Did you update the firmware? ACC only works with the special Tesla version of the firmware, which is not pre-installed.

Ah - thanks. I have 2.5.5. but just assumed you had to put it in TR mode.

By the way, the OVMS site has a link to a free program for the PICkit Express software - but that software seems to be $59 now.

I assumed exactly the same (ie that acc firmware was already loaded .. its not)
I have the picKit and software & you are welcome to borrow. Software was free: PICkit 2 v2.61.00 Setup A.zip and the firmware is :V2_TR_production.hex
PM me if you want it emailed.

Me, too.

Me, too.

It took me a helping hand from Mark to realise I had to blow the chip.

i have an interesting mini issue: when parked in my garage the OVMS module gets a mediocre reception both of GPRS and GPS.

some of the time ACC queries will tell me about charging parameters I have set up for a scheduled charge then a few moments later it says that there is nothing at location #0.

it sometime does the scheduled charge, and sometimes doesn't.

is it possible that if it has not got a real time location when the clock ticks over a minute change, it will miss the charge kickoff? If so, would it be possible for the next firmware to cache the last seen location? The car should surely be pretty certain where it is or was just now and especially if stationary!

We pretty much work off wherever the car says it is via the GPS messages on the CAN bus.

The ACC location stuff does work only when the car is driving (ignition on). It sees if you enter a known ACC location and acts appropriately.

Can I interrogate the ACC parameters when the car is off to see if the settings are as I want them? Or do I need to be at the car with it on?

This could explain why I get a lot of ACC #0 responses

If the car isn't at the location you want to check, then use "ACC PARAMS? n", where "n" is the location number.

 

[markwj]

If you don't specify the location to an ACC command, then it will use the 'current' location (the location the car is currently in). If that returns #0, that means it doesn't think it is in an ACC location.

I realise that : it IS in a known location but I think it sometimes gets confused as to where it is because it is inside a concrete garage.

It's based on the last known location.

Hi,

I've got ACC working. It reliably opens my apartment complex garage door now when I drive up, but by the time I drive through the underground garage and park, the cooldown doesn't work. It worked the first time I programmed the location. I set it right outside the parking garage door, where I still have cell phone service. Once I get into the garage, cell service is spotty. If I text the OVMS right before entering the garage to request cooldown, it works.

Is there something I'm missing about how cooldown with ACC works?

I have two different locations I've programmed to try and get it to work. The homelink started working when I programmed #2:

ACC #2 GPS redacted Enabled Cooldown Homelink #1 Charge at plugin Mode: standard (0A)

ACC #1 GPS redacted Enabled Cooldown Homelink #1 Charge at plugin Mode: standard (0A)

I got it to register the current location where the charger is, and it is 0.00012 , 0.000216 degrees off from ACC #2.

Is there a way to increase the radius for cooldown? Or should I keep adding locations until I cover all the GPS possibilities in my garage.... Thanks!

Quick update:
It is definitely at ACC #2 right now while charging. I deleted ACC #1, since ACC #2 looks closest to the real location on google maps and to the current location.

Any tricks to get it to engage cooldown automatically? Drive in the ACC zone, trigger homelink, park, key off, open the driver door, open the trunk, get out cables, open the charge door, plug in. Seems like the obvious way to do things...

Update:
Hot weather today. When I arrived home the battery was 104F and it triggered cooldown. Looks like it is working.

Now I need to try to get the blower upgrade... The hot weather kicked me into the red performance mode right away.

Does anyone know what temperature the Motor should be at rest? When I look at OVMS after the car is parked overnight after 14 hours it shows the PEM, motor, and battery with temps...

Is this the temp NOW or 14 hours ago when we shut the car "off"? (Like the tire pressure)

We seem. Be getting some weird ideal mile losses the past week and I'm trying to figure out if I need to do cool down or if it's age...

Pull the logs to see if the CAC is dropping, and also check if the same brick is consistently the lowest.

I wouldn't worry about motor temp. I have a feeling that motor temp doesn't get updated once the car is parked.

Once the car goes to sleep, the numbers appear grayed out to show they are stale. You can wake up the car (tap the trunk, and choose WakeUp). Within a couple of seconds of that, you should get bright white up-to-date numbers. Car will go to sleep again 5 minutes later.

Any chance of an app update to trigger cooldown from within the app?

My workload is sky-high at the moment, so unlikely any time soon. When v3 hardware comes out, there will be an App refresh.

Note: The Apps are open source. Happy to help if someone else wants to make the necessary changes.
