Do I need to change schedule with 240v charger?

Yes, the car knows it finishes quicker as soon as it registers 240v on the EVSE. The time to full charge displayed on the dash should be ~2hr. If you set the schedule for the time of departure (not Charging Start time), then it will start accordingly later than when it was on the 120v EVSE and finish before the set "departure" time.

 

the estimated charging time is not accurate, i'm sure it's working fine. it either charges the car or it doesn't.

keep in mind, the charger is in the car. the evse is just a control system

 

With "Charge Now", that would be an appropriate display and response. I am sure if you used the schedule, the charging would have started ~4 later than when you used the 120v EVSE.

Your profile says you have a 2020 Prime Advanced. Started on 2020 and up, they changed the trim levels. So, that should be 2020 Prime Limited. If it is pre-2019 Prime Advanced tri, or if your is any trim level in the 2020 model, I believe it comes with the Safety Connect telematics. IIRC, with Safety Connect (and its Connected Services) enabled, you can still use the Toyota App to check the charge level remotely on your phone?

That being said, I don't use Toyota App, and I opted out of the Safety Connect. The app is buggy and there has been a lot of reports by users on PC not being able to use the functionality. A remote charge monitor is one of them. So, you may or may not be able to check the charge level using the Toyota App.

 

Check your time & date settings on the car. If the car's time or date is set incorrectly; your scheduled charging won't function predictability. If you don't have an activated schedule; the default is charge now.
When you first plug in the car; it does a current/voltage check to set charge parameters - after about 30 seconds; if you open any doors -it'll tell you how long it's going to take to full charge.

Hope this helps....
