Yes, it says something like that on the sleep page, but in the support docs it says the following: There are two different data calls that TeslaFi uses from the Tesla API to determine the vehicles state. 1. Vehicle Only a few data points are returned from this call. The most useful point is the online state of the vehicle such as online/offline/asleep/waking/unknown. The important part of this call is that it can be called without affecting the vehicle’s state. This means it can be called and it won't prevent the vehicle from sleeping and it won't wake the vehicle if it's asleep. 2. Data This call returns all the useful data that TeslaFi used to display your information. Things like odometer, battery charge, range, speed, shift state and many many more are provided from this call. The important part to remember from this call is that it will keep your vehicle from sleeping and will wake your vehicle if it's sleeping when called. So if we know the vehicle won't sleep by calling the data call we can pause using the data call for a certain amount of time and try to put the vehicle to sleep. The only issue is that we don't have any way of knowing when the vehicle is ready to go sleep. The onboard computers may be doing some work, a software update may be downloading, etc.....only Tesla knows. Since it is still returning the state each minute it must just be in the "Vehicle" call state. So I don't think it would miss much if you start a drive in this time frame.
