About

Microsoft 365 - To Do connects Home Assistant to Microsoft 365 To Do lists through the Microsoft cloud. It adds the lists as to-do entities, so tasks can be read, created and updated from Home Assistant. Actions cover creating, updating, deleting and completing a task, plus creating, updating and deleting checklist items within a task. Options let the user choose which lists are enabled, cap how many tasks are retrieved, shift the due time window forward or backward in hours, and show completed items. Setup happens in the UI with a client ID and client secret, with an alternate authentication method available, and it requires the Marketplace. A diagnostics download is available for bug reports.

This project would not be possible without the wonderful python-o365 project.
I work on this integration because I like things to work well for myself and others. Please don't feel you are obligated to donate, but of course it is appreciated.
