I Order the following pack from Xiaomi.
Mi Smart Sensor Set, Weiß, Control Hub, Bewegungssensoren, Tür-/Fensterkontakt, Drahtloser Switch (6er Set) https://www.amazon.de/dp/B07KXN6S74/ref=cm_sw_r_wa_apa_i_2C-yEbHGBCPPR
Now I want to insert the hub to openhab. In a lots of guides it says with about and then clicking on version number or into the white space. But nothing of these works. Has anyone an idea how I get the key or how I can activate the developer mode ?
