openhab-addons: [mihome] Bridge uninitialized after reboot + NPE

I’m experiencing a weird behavior of the Xiaomi MiHome binding. After reboot I noticed that my setup doesn’t respond. My setup has a textual config aligned the same way described in the docs of this binding

Expected Behavior

The binding should work properly.

Current Behavior

My sensors are “UNINITIALIZED” whereas the gateway has “UNINITIALIZED - BRIDGE_UNINITIALIZED” status.

Here’s the Null Pointer Exception:
