I just experimented with Deep Sleep, it works awesome. However I drove while the vehicle was in deep sleep and it was not recorded. I suppose that's normal.
It would however be a great idea to be able to manually start Deep Sleep on the website. And also manually start Sleep, using a button (where the Wake button is). That way I can put TeslaFi in deep sleep as soon as my car is in the garage and not have to wait for hours before it goes into normal sleep.
I suppose you are aware the Tesla have problems in Europe to wake vehicles since a few weeks (waking never works anymore, not using the app or API) and no solution is in sight.
