Is it possible you use the schedules I defined in the Dreame app that way? Because a schedule is also a bunch of settings (clean/mop/what rooms/...). Or does this mean you have to create your own settings away from the app and do it that way?

Not possible yet.

Thanks for your response, and for all the work you put into this. Schedule editing might be a lot of work, but maybe it would be nice to start with the possibility to call the schedules as a service, t.i. enable/disable a schedule, or send a new start time. There are cards like the scheduler card that we then can use to change the schedule from within HA. Just an idea.
