Lost connection
Sometimes the plugin seems to lose connection to the Roborock. When that happens the Roborock is accessible through the Xiaomi Home App and there is no error messages in the HomeBridge log. The plugin still seems to report states from the Roborock in the log when that happens as well:
```
[2020-3-15 15:29:23] [Staubsauger] INF getCleaning | roborock.vacuum.s5 | Cleaning is true
[2020-3-15 15:29:23] [Staubsauger] INF getCleaning | roborock.vacuum.s5 | Cleaning is true
[2020-3-15 15:29:23] [Staubsauger] INF getBatteryLow | roborock.vacuum.s5 | Batterylevel is 100%
[2020-3-15 15:29:23] [Staubsauger] INF getCleaning | roborock.vacuum.s5 | Cleaning is true
```
In this case I gave the command to start a room cleaning, the HomeBridge log says the state is changing to "Cleaning" but the Roborock doesn't do anything.

Restarting the homebridge server solves the issue. I can't reliably reproduce it.

Cheers for this plugin,
