Funny, I was thinking of that recently as I had simply wanted to pre-set the Remote timer to turn on the heater just like we can use the Remote for charging control. After experiencing the remote-control capabilities of the always-connected Tesla and its app, our little Remote is sooo last-decade. Have no idea how to hack into our unit and bypass it. Are you plugged in and charging while at work, or is the car just sitting there disconnected?
