[BMWiX60M]

I have ChargePoint at home. I use home charging schedule with ChargePoint app. I have set up to charge the car in OFF Peak hours and it works really well. While I am away from home, most likely I want to start charging right away so ChargePoint app doesn't interfere with that.
Sometimes I use BMW app to change Climate Precondition/Departure time.

If I may add to what you wrote here to help out VancouverIX:
In addition to setting the the offpeak charging times, I use the BMW app to set the charging to immediate as well as change the maximum charge (60%, 80% 90%) to whatever my anticipated usage will be. I sometimes also change the charge rate from 48A to 32A or 24A for AC charging so I can charge the car at a slower rate at night I desire. With the BMW App set to charge the car immediately, I simply plug in the ChargePoint Wallcharger at the end of the day; the car does not start charge until my designated time at night in the ChregPoint App and turns off charging either my max-charge set in BMW App or cutoff time set in the ChargePoint App. Also, with the BMW App alwasy set to charge immediate, I don't have to change it when I go use a DC Fast charger. All this works out nicely, except for one thing I am yet to figure out: how to tell the BMW App to stop charging at a DC Fast charger after my free 30mins of EA charging is over but the car hasn't reached the 80% limit I normally have it set.

The initial cost of the ChargePoint Wallcharger was $US750 for the cost of the charger plus $US500 paid to a licensed contractor. (For the safety of myself and my family, I made sure that the wire gauge used was 4 with 50A breakers and not all contractors wanted to do that). Other than the startup cost, I love the WallPoint charger and App, it easily pumps out the 11KW that the car uses and is really plug-and-play from my perspective. VancouverIX, I hope this gives you adequate detail for your research.
