Quit working today for Xaiowa E Series
Today this plugin unexpectedly quit working for our Xiaowa E Series.
In case this information is of any relevance this plugin runs on it's own child bridge and I have assigned the robot a static IP on my router.

Homebridge throws the following error:
`ERR connect | miio.device, next try in 2 minutes | Error: Could not connect to device, handshake timeout`

I've seen this error before when my IP address or token changed, but I checked them and they are correct in the plugin's configuration, so this must be a different cause than usual.

I've also seen the following variant of the error today and this one is new to me:
`ERR connect | miio.device, next try in 2 minutes | Error: send EHOSTUNREACH 192.168.4.70:54321`

Any help would be highly appreciated.
