Sorry for the late response. Did you get it working?

[anorexus]

Ah yes, that's a silly beginner mistake, I just simply re-install the component and it's working now. Just wondering if I can use the gateway function too or not?

[syssi]

Which revision of the device do you own (v1, v2, v3)?

[anorexus]

It's v3

[syssi]

You are a lucky guy! The recent gateway firmware of the v3 introduces the LAN protocol. This Home Assistant PR introduces the device support for your device at the xiaomi_aqara component: https://github.com/home-assistant/home-assistant/pull/13540/files

Nice!
One thing, how do i set it up to work with my door sensor?
Also alexa didn't detect my aqara ac companion, is alexa can't detect all custom component?

Thanks

[syssi]

Please describe your setup and what do you try to achieve?

1. You should wait until your device is official supported by Home Assistant -> Merge of the Pull Request. If you cannot wait anymore: You have to use the feature branch.
2. This custom component doesn't provide support for the gateway function! You have to use the xiaomi_aqara component.
3. Setup the xiaomi_aqara component. A encryption key is needed (read the manual!): https://www.home-assistant.io/components/xiaomi_aqara/
4. Press the button of your gateway three times and the pairing button of your door sensor once. A chinese voice will confirm the successful pairing
5. Restart Home Assistant. The paired device will show up as a binary_sensor entity now.
6. Read the manual how to setup automations: https://www.home-assistant.io/components/binary_sensor.xiaomi_aqara/#door-andor-window
