There's no pretty way to fix this, which is why I've left it. Homebridge is built with the idea of directly interfacing with the device, while this plugin communicates with the VeSync API, which communicates with the device. Homebridge also does not allow us to extend this "slow down" timeout in any way.

One way to handle it is to not wait for a response from VeSync, but that will lead to state mismatches if the API returns a bad status.

Setting this plugin up as a child bridge can help, and ensuring your internet is stable. Other than that, there's not much I can do about it.

I just realized that you have "showOffWhenDisconnected" set to true in your config. As stated in the README, that setting will trigger those warnings because Homebridge can't actually communicate with the device.

Ahhhhhh! That makes sense. I'll adjust the config. Thanks a ton!
