Questions about the mini connected app

When I can't find an answer about the MINI Electric, I look for similar questions on BMW i3 forums. The originator of this thread speculates that you cannot set the preconditioning temperature (this is also the case with my Honda Clarity Plug-In Hybrid); the car decides how warm or how cold to make the cabin temperature. The esteemed @Tom Moloughney has a good Inside EVs article "How Preconditioning Works," where he interviews a BMW engineer. I didn't see any information about setting the temperature there, however.

The engineer interviewed in Tom's article discusses problems achieving 100% charge when preconditioning while charging on a Level 1 EVSE--at least when preconditioning in cold weather:

> When preconditioning using a Level 1 charger, the car will always be below 100%.
> It could be about 80% or lower. (Because it uses more energy than the 120v source
> can provide.) When using a Level 2 charger, the SOC could be slightly under 100%
> as the vehicle electrical load stays somewhat constant while the charger will switch
> off and on.
