Integration doesn't recover from loss of internet

[HandyHat]

Hey there, thank you so much for the integration!

I've been experiencing some connectivity issues with my air purifier and have managed to reliably reproduce it. If there is any issue with the local network after Home Assistant starts up the integration seems to break and doesn't recover until Home Assistant is restarted again. I first noticed this in December but didn't want to open an issue until I could reproduce it.

To reproduce, I restarted my router at 13:16:40. Then, once my local network had fully come back up, I tried to turn off my air purifier at 13:21:00. This raised DysonNotConnected. I tried to reload the integration afterwards but this did not fix it. The only way to fix it is to restart Home Assistant.

Here are the debug logs:
