This is the reason I use OptiWatt for scheduling the charging. It supports the use case you specified.

Preaching to the choir on that one... Sometimes I wonder if they even have any UX people at Tesla, hahaha.This is not me. This interface is royally fudged.

This is what I do so the car is ready at 430 am and off peak hours. I keep it at this time so i don't have change anything daily. I did notice that when I checked the app prior to 430 am departure it was still charging, so it waits to the selected departure time and non peak hours.I'm trying to use the scheduled departure through the app and it doesn't work. It appears simple, I set the time, 6:30 AM and click OK. The charge level is high enough it should start charging immediately. It doesn't start charging and if I go back into scheduled departure the set time has changed to 8:00 AM.
If I change the charge level so it will start shortly and enter the time for scheduled departure. I leave and wait a while. If I reenter scheduled departure, the time has reset again to 8:00 AM.
What am I doing wrong?
Your photo shows you told the car to finish charging at 6:30 am. What that “off-peak charge” really means is that you want to car to finish charging at 6:30 am. It is best to set both precondition and off-peak charge to the same time, basically when you want to leave the house. In the summer you can leave precondition off.This is what I do so the car is ready at 430 am and off peak hours. I keep it at this time so i don't have change anything daily.

Since you do not need preconditioning or care about utility rates just turn everything off. Plug in the car whenever you want and let it charge then and there. No need to add any complexity.So I want to leave at 6:30 am tomorrow. I don't have any use for preconditioning. That will simply use extra energy and lengthen the charging time. I also have no utility rates that I care about.
So I have to set one or the other, precondition or Off-Peak Charge time, right? Can I just set Off-Peak Charge time to 6:30 AM, and it will start charging when I need it to start charging to be at the set charging level by 6:30 AM?
As a test, I left the precondition time to 6:30 AM, but turned off Precondition. I set the Off-Peak Charge time to 5:30 AM and enabled that. When I checked the charging state, it said it turned off the charging, and "Car will charge during off-peak hours to depart by 6:30 AM". WTF? I'm wondering if this will schedule it to cut off at 5:30 AM. Technically, that's ready by 6:30AM. I'm leaving it like this, to see when it starts charging.

I do not see how this has any relevance to you preconditioning question, one way or the other you charge the car. But,I suppose no one has told you about the additional wear you put on the battery by charging to high states of charge and leaving it sit like that? The battery is the most expensive part of the car, second only to the software. I like to baby it, even if you don't care about yours.
On my Model 3 I've had success by setting the Scheduled Departure, Off Peak and Precondition times to the time I want to depart. I've not had one problem since using this strategy. I don't have any off peak rates to consider either.
I do not see how this has any relevance to you preconditioning question, one way or the other you charge the car. But,
Charging speed is a complex issue, but assuming a battery capacity of say 65 kWh and a max rate at home of 11.5 kW, the “C-rate” is just 0.18, which is a non-event.
As to being at a high state of charge, unless you are taking it to 100% there is again no issue. In fact Tesla’s official recommendation is to leave the car plugged in all of the time.
Feel free to do as you wish, but don‘t imply that I or anyone else does not care about their car.

@gnuarm, my posts #34 is in response to your post, shown below

Agree Tesla makes things too difficult and makes it worse with bad terminology! Since you are interested in the departure function note the following:
How this helps!
- Ignore the schedule charge function, in fact turn "Enable Scheduled Charging" the slider off.
- On the Schedule Departure page, you have two options that are totally independent:
- If you turn on the "Precondition" option, then the departure time above has meaning, otherwise it does not. If, for example, you want your car battery and temperature to be ready for a 6 am departure, set the time in the departure window to 6 am and your car will be ready for you at 6 am. You can enable this function for all week or just on weekdays.
- If you enable "Off-peak charge" you will see new options below. This is terribly named!!! If you turn this on and set a time in the "Off-Peak End Time" window below, the car will will then automatically start charging at a time so the car reaches the desired SOC at the time you have set (actually about 15-minutes prior.). You can enable this function for all week or just on weekdays.
