Currently login is possible only by username and password. See issue #1
Support
sensor of upcoming order
single data coordinator for updates
Cannot support - helper for "date and time of upcoming order", there is no visible API.
Maybe could be extracted from mobile APP. Are you interested? You can buy me a coffee and I will take a look.
