In case someone is having similar trouble with a Dyson fan that was working prior to 0.111 (0.111.0 and 0.111.1), here’ a link to the issue I opened on GitHub.

Interesting!

Normally, I have the following when I check DNS-SD via https://apps.apple.com/ca/app/discovery-dns-sd-browser/id1381004916?mt=12

	475_<REDACTED_1>

However, today when I checked, I only had

While my Dyson Pure Cool Link™ TP02 was on network and responding to the app, it didn’t seem to be advertising itself!

So, in the spirit of “don’t frown, power down” I unplugged it from the wall, waited 30 secs, and plugged it in again.

It is now advertising itself as expected.

I then restarted Home Assistant 0.111.1, and the warning has cleared and the device is available and responding to Home Assistant.
