Ah, got it! Tesla app opens the door, and the IOS widget opens the door. That makes my list 10 now, and that doesn't include the lightshow, whatever that is.
Apple Watch has an app available called *Watch for Tesla*
It's really useful in showing you stuff like charging stats, inside/outside temps, and has customizable controls.
I would count anything that goes through Tesla's server as the same method, whether it is the Tesla app, a third party app, or a watch that triggers this to happen.
