Autoroom feature issue
Hi, 

I would like to use autoroom feature for my Xiaomi Vacuum Mop Pro. Plugin is working with simple commends as start, stop, return to the dock but when I try to use autoroom feature I got this:

[9/2/2020, 4:55:05 PM] [Vacuum] ERR getRoomMap | Failed getting the Room Map. Error: Call to device timed out
    at Timeout.retry [as _onTimeout] (/usr/local/lib/node_modules/homebridge-xiaomi-roborock-vacuum/miio/lib/network.js:519:23)
    at listOnTimeout (internal/timers.js:549:17)
    at processTimers (internal/timers.js:492:7) {
  code: 'timeout'
}
[9/2/2020, 4:55:05 PM] [Vacuum] ERR connect | miio.device, next try in 2 minutes | Error: Call to device timed out

I have named all my rooms in Xiaomi App. Any idea what's still not right?

Thanks!
