Other commands seem to work. E.g. Stat, version, see attached picture.
What I mean with message from app is a notification that shows up at my phone as notification of message receipt. There is no change of parameters in the app itself.
Groet / Regards

>>> V2_TR_production.hex V2 Hardware Module, Tesla Roadster full firmware
>>> Support for LOGGING (charge and drive)
>>> Support for ACC (Advanced Charge Control) - Tesla Roadster only at the moment
>>> Lots of other little nice fixes and enhancements
>>> Apart from overall reliability testing (making sure it is stable in the cars), the two things I need help with are the LOGGING and ACC functions.
>>>  Logging
>>> The logging code is enabled by setting opt-in feature (#13) bit 1 (to log drives) and/or bit 2 (to log charges). Or, you can just set feature #13 to 255 and opt-in to everything :-)
>>> Once you've opted in, whenever you complete a charge or drive, the car will submit a summary record to be stored on the server. You can then use the prototype HTTP API, or perl client, to retrieve those records for your own purposes.
>>> Note that there is a privacy concern here, as both record types (drive and charge) store GPS locations - this is the reason why it is opt-in.
>>> The testing I need done is just to ensure that this works for you, and that the resulting logged drives/charges match what you are expecting. It would also be useful to confirm if this works on all supported cars (which it should).
>>>  Advanced Charge Control
>>> The Advanced Charge Control system is designed to supplement the (aka take over from) vehicle's own charge scheduling. It should support any vehicle with charge control, but at the moment that means only Tesla Roadster. It has some pretty sophisticated features. For the moment, it is setup via SMS, but in future we will allow smartphone Apps to do this. Once setup, it runs autonomously, and doesn't even require a cellular connection.
>>> ACC works from the concept of a 'charge location'. This is a geofenced location that is used for charging, and you can configure up to 4 of these (numbered #1 through #4). To define the car's current location as a 'charge location', sms "ACC HERE" to the car, and it will allocate a free slot and reply to you with it. You can use "ACC NOTHERE" to clear the current location.
>>> If you want to clear a particular ACC location, you can sms "ACC CLEAR n" (to clear one location), or "ACC CLEAR" (to clear all locations).
>>> You can show the current status off ACC with “ACC STAT”.
>>> You can show the ACC details for the current location by sms "ACC PARAMS?" (or for a particular location by "ACC PARAMS? n" - which is very useful if you have crappy cellular connectivity like I do).
>>> The ACC parameters for a particular location are configured with the "ACC PARAMS" SMS. You can list a location number (1, 2, 3 or 4) as the first parameter - or don't specify location if you just want to configure the current location the car is at. After 'ACC PARAMS", you can set the parameters you would like, from the following:
>>> COOLDOWN - perform a cooldown charge (13A range mode, with cooling cycles) when the car is plugged in at this ACC location
>>> NOCOOLDOWN - don't do a cooldown charge (default)
>>> HOMELINK n - activate homelink when the vehicle drives to within 100m of an ACC location (the idea is to open our garage door / gate automatically as you approach)
>>> NOHOMELINK - don't activate homelink (default)
>>> CHARGEPLUGIN - charge the car on plugin (but after cooldown, if enabled)
>>> CHARGEAT HH:MM - schedule charge to start at the specified time (hours:minutes, 24hour clock)
>>> CHARGEBY HH:MM - schedule charge to complete by the specified time (hours:minutes 24hour clock)
>>> NOCHARGE - don't charge (default)
>>> LIMIT n - limit charge current to n Amps - must be specified for all CHARGE* actions
>>> MODE m - set charge mode (where "m" is STA(NDARD), STO(RAGE), RAN(GE) or PER(FORMANCE)) - must be specified for all CHARGE* actions
>>> STOPRANGE r - stop charge when range "r" is reached (specified in vehicle units, set to 0 (default) to not limit).
>>> STOPSOC s - stop charge when SOC "s" is reached (specified as a percentage, set to 0 (default) to not limit).
>>> The actions to take at a particular ACC location must be enabled with "ACC ENABLE" (or "ACC ENABLE n") before they will work. You can also disable with "ACC DISABLE" (or "ACC DISABLE n").
>>> If you are using CHARGEAT or CHARGEBY, you need to specify the timezone of the vehicle. This is parameter #23 and is specified as HH:MM offset from GmT (with an optional leading "-" if west of Greenwich).
>>> The default temperature limit for cooldown is 31Celcius, and time limit is 60 minutes. If you want to change these, you can set parameter #15 to templimit:timelimit (e.g.; "31:60").
>>> Note that you can also cooldown manually, while charging, with the SMS command "COOLDOWN", and see the status with SMS "STAT".
>>> I've spent quite some time testing CHARGEPLUGIN, CHARGEAT, COOLDOWN, LIMIT, MODE, STOPRANGE and STOPSOC - hopefully those are ok now, but the control logic does need wider testing. The CHARGEBY option is still giving me random problems, related to the charge time estimated - I am still working on that. I've also been unable to test HOMELINK and would be very interested to see if that works.
>>> Some notes on cooldown on Tesla Roadster
>>> The cooldown algorithm is to start a range mode charge at 13Amps, and to monitor the HVAC system of the car. Once the HVAC starts, runs for some time, then stops, we call it a 'cooling cycle'. We keep a record of how many such cycles have occurred.
>>> Once we detect that the HVAC has stopped, we try to start it again. The logic at the moment is to switch to performance mode for ten seconds, then back to range mode, once every minute until the HVAC starts again. The _best_ way of starting the HVAC is to stop and start the charge, but that is painful on the contactors, so we don't do it. Switching Range->Performance->Range seems to be the second best, but I remain unconvinced that it makes much difference. In Hong Kong summer weather, I get one cooldown cycle every ten minutes or so. I can drop 6 to 8 celcius in one hour.
>>> The cooldown will stop after either the desired temperature is hit (based on the temperature of the hottest brick in the battery) or the cooldown has been ongoing for the time limit.
>>> I'm happy that the code is reasonably stable now, but really need help testing this in a larger number of cars. If you do see a problem, please get me (by eMail to OVMS developers mailing list, or my personal address):
>>> Output of "SMS STAT" for the specified location
>>> Your vehicle id
>>> Output of base64 parameter string (from the cellphone app) - copy-and-paste
>>> Date/Time you entered the ACC location (with timezone)
>>> Date/Time you plugged in at the ACC location (with timezone)
>>> In the smartphone app, call up the Features and Parameters screens (so the server logs those, and I can check)
>>> Description of the problem you have
>>> Please also share success stories. It is good to know what works.
