我想将我的小米网关 v2欧盟版与openHAB一起使用。为此，我需要在小米米家应用程序中启用开发者模式。这些是来自 openHAB 的完整说明：

1.  Select your Gateway in the MiHome app
2.  Go to the "..." menu on the top right corner and click "About"
3.  Tap the version number "Plug-in version : 2.XX.X" at the bottom of the screen repeatedly until you enable developer mode
4.  You should now have 2 extra options listed: `wireless communication protocol` and `hub info`
5.  Choose `wireless communication protocol`
6.  Tap the toggle switch to enable WiFi functions. Note down the developer key (aka password), something like: 91bg8zfkf9vd6uw7
7.  Make sure you hit the OK button (to the right of the cancel button) to save your changes

我被困在#2：Go to the "..." menu on the top right corner and click "About"- 没有关于菜单。我尝试将地区从德国切换到中国，但结果相同。

如何在小米米家App开启开发者模式？欢迎任何想法。
