Enable developer mode in Xiaomi Mi Home App

Question

I would like to use my Xiaomi Gateway v2 EU-Version with openHAB. In order to do that I need to enable the developer mode in Xiaomi MI Home app. These are the full instructions from openHAB:

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

I'm stuck at #2: Go to the "..." menu on the top right corner and click "About" - there is no About menu. I tried switching the region from Germany to China but with the same result.

How to enable the developer mode in Xiaomi Mi Home App? Any ideas welcome.

Answer 1

According to this forum, in the newest version you are :

no longer able to activate the Dev Mode

However you can :

replace the Xiaomi Hub with a CC2531 USB sniffer that enables you to communicate directly via Zigbee with your Xiaomi sensors.

Answer 2

On my manual there is a sticker with the code also on the HUB But the code on the manual (HUB) is with 8 numbers 4 x 4 You have to put it into HA as xxx-xx-xxx and that works for me !
