Home Assistant component for original firmware Sonoff / eWeLink switches

Simple Home Assistant component to add/control Sonoff/eWeLink smart switches using the stock firmware and cloud capabilities.

---

WARNING: completely deactivate the sonoff component from HA while doing a firmware update, due to auto-relogin function you might be kicked out of the app before the process is completed. I would not be held liable for any problems occuring if not following this steps!

CHECK COMPATIBILITY LIST BELOW! IF IT DOESN'T WORK FOR YOUR DEVICE DON'T COMPLAIN AND OPEN A PROPER ISSUE

Setup

To setup add to your configuration.yaml:

sonoff:
  username: [email or phone number]
  password: [password]
  scan_interval: 60 (optional)
  grace_period: 600 (optional)
  api_region: 'eu' (optional)

And copy the *.py files in custom_components folder using the same structure like defined here:

 custom_components
    ├── sonoff.py
    └── switch
        └── sonoff.py

email [Deprecated] only for compatibility, may be eliminated in future.

username the username that you registered for ewelink account be it an email or a phone number (the phone number should lead with region number, '+8612345678901' for example).

scan_interval you can define how fast the state of devices is refreshed (by default every 60sec). for example if you change the switch from an external source like Alexa or Google Home the change will show up in HA in maximum less than specified period, while changing it using HA interface/actions/etc it's instantly

grace_period eWeLink app allows only one active session at a time, therefore this will temporarily block HA refreshes for the specified amount (in seconds) to allow (or better said after) you to login in the app and do required changes to your devices. following that sonoff component does an internal re-login invalidating the mobile session and the process restarts. (as a workaround for this, you can create a 2nd account and share the devices from main one, therefore one will be used in HA another one in mobile app)

api_region this component tries to find, login & connect to the proper region assigned to you. specifying a proper region will help the component to load faster and reconnect after the expired grace period explained above, possible values: eu (default), us and cn

This is just a proof of concept because I searched for it and there was no implementation to use Sonoff/eWeLink devices without flashing them. (althought I know how to do it, I don't have a real extensive usage for now and I prefer to keep them on stock firmware).
