Why would you want to support disabled gateways?

[syssi]

The auto discovery picks up all available gateways. May be selected ones shouldn't interact with HA.

[syssi]

The title and description of the PR is misleading.

[kerwin612]

emmm...yes,,my english is so bad...@syssi thanks for your help

[Kane610]

Wouldn't it be better to use the configurator for this?

[syssi]

Could you explain this?

[Kane610]

The configurator would allow configuration of each identifies gateway directly in the gui. Then it would just be a check box to disable/ignore

[syssi]

Do you mean the hassio add-on? In this case the approach here is the right one.

[syssi]

Could you rename the setting from "disabled" to "disable"?

[kerwin612]

sure

This PR requires an upcoming release of PyXiaomiGateway.

[syssi]

I've released PyXiaomiGateway 0.9.4. Please update the requirements of homeassistant/components/xiaomi_aqara.py.

[syssi]

I've added some docs: home-assistant/home-assistant.io#5388

[syssi]

requirements_all.txt is not up to date
Please run script/gen_requirements_all.py

[syssi]

Instead calling gen_requirements_all.py you could increment the PyXiaomiGateway version at ./requirements_all.txt.
