Hello Proton Team,

I am writing to strongly request a native integration or official API support for Home Assistant backups to Proton Drive.

The Context: Many privacy-conscious users run Home Assistant (the leading open-source home automation platform) on devices like Raspberry ***. For these users, securing local backups in a zero-knowledge cloud is a critical security requirement. Currently, Proton Drive is the ideal target due to its end-to-end encryption, but it is inaccessible for automated backups.

The Problem:

No Public API: Unlike Google Drive or Dropbox, Proton Drive lacks a public, documented API that allows third-party applications to authenticate and upload files without triggering aggressive CAPTCHA/abuse protection (Error Code 9001).
No Official Addon: There is no official Home Assistant addon for Proton Drive.
Workarounds are Fragile: Existing community solutions (like Rclone or mounting via desktop clients) are unstable, require complex manual CAPTCHA solving, or need a separate physical device, which is not feasible for many users.

The Request: We ask Proton to:

Develop an official Home Assistant integration (addon) that securely handles authentication and zero-knowledge encryption for backups.
Or, provide a stable, documented API (with OAuth/API Key support) that allows trusted third-party clients to perform automated uploads without CAPTCHA challenges.

Impact: Implementing this would align perfectly with Proton's mission of privacy and security, enabling thousands of users to protect their smart home data without compromising on convenience or security. It would make Proton Drive the default choice for privacy-focused smart home enthusiasts.

Thank you for considering this request.
