Error communicating with Robot Vacuum
Hello,

I have an issue connecting to my new Mi Robot Vacuum-Mop device. 
Token and IP read is correct (I can clearly see in the log if I change the token and it is not correct).

Homebridge is running on a raspberry pi4 4gb since a week, so it is a new version running:
Hombridge Version v1.1.2
Node.js Version v12.18.3
Npm Version v6.14.8

After connecting and accessories appear they remain unresponsive.
Some data is retracted e.g. IP, model, Firmware version, other info is undefined or unknown. 

Here is my log content from the connection onwards:

An example of me trying to send a find request to the robot Vacuum:
