Not normal. It should be sleeping for far longer periods of time. Too many things can cause it to constantly awaken. Example of a few.... keep fobs far away from car, turn on energy savings, and turn off always connected feature in the car display. Use the default settings that TeslaFi suggests in the settings menu, close smartphone apps when not in use, unplug the charger cable if you are not charging, don't try to open doors (even if key fob is not in your pocket). Try those first. FYI, my car was in sleep for 15 hours and would have slept longer if I had not intentionally awakened it.
FlyF4 is correct. It could also be caused by another program using your token and waking the car up. I would try changing your Tesla.com password and generating a new token on TeslaFi as well to make sure nothing else is using your token.
