Mark, Sorry for all of the emails, I just figured you would want to know how testing is going. Never mind the earlier ones - TPMS data has re-appeared. I think that I needed to do a drive after the module was re-installed to get the data read in (not sure about that). I have opted in to charge logging, so you can see what is happening. Output of "SMS STAT" for the specified location STAT? Standard - Charging 232V/40A Full: 88 mins SOC: 73% Ideal Range: 133 mi Est. Range: 125 mi ODO: 22,715.3 mi CAC: 147.76 ACC STAT ACC Status #1 39.072536, -77.131168 Enabled Cooldown Charge by time 03:44:00 Mode: standard (0A) Your vehicle id ROADSTER76 Output of base64 parameter string (from the cellphone app) AqkrEWe+Gt4BQwAA4AAAAAAAAAA= - Date/Time you entered the ACC location (with timezone) - 22 September 2013 15:41 EST - Date/Time you plugged in at the ACC location (with timezone) - 22 September 2013 approx 16:45 EST - In the smartphone app, call up the Features and Parameters screens (so the server logs those, and I can check) - Done. Description of the problem you have I set the ACC params for Cooldown, Chargeby 08:00, and Standard mode. When I plugged in, the charge started immediately, with no cooldown phase (probably expected, since the battery is already below the threshold). Further attempt to request a cooldown made no change. Standard mode charge proceeded, even though I would have expected a timed charge to start some time tomorrow morning (and the STAT? command now reports time to full at just 88 minutes). Also, I set CHARGEBY for 08:00, but the ACC STAT return seems to indicate it is set for 44 minutes after the time specified. If it were working, it would be late. Now that I look at it again, I don't understand the time setting at all. I followed your insructions to use a leading "-" as I am West of GMT. I would expect the reported CHARGEBY time to be either 08:00 (local) or 13:00 (GMT), but I'm seeing 03:44. Many thanks - will try to help with any testing you need in a timely manner. ......curt
