How about Bluetooth mod control? Oh, wouldn't you know... Already done by the master of gimmickry!
Personal Vaporizer E-Cig - SmokTech - XPro BT50W
smok XCube 2 did it as well.
Actually a well built device.
I've got one that I've been using for nearly two years now, and another one still in the box.
The Bluetooth was fun to play with, but after I got a new phone, I can't find the app for it anymore.
