Govee Smart Fan 2 w/ Matter: thoughts and connectivity/reset tips

I picked up a couple of these fans for my home, and after some initial setup quirks, they're working reliably with Matter and HomeKit. HomeKit lets you adjust fan speed and oscillation; you cannot adjust the oscillation angles. These fans can push a lot of air if you want, and on lower settings they're totally silent while still providing a pleasant breeze.

Folks are discussing it on that other site, but since I don't use it, I wanted to post some things here. Hopefully so DDG/Google/Bing can still find useful results. Someone can link Redditors to here if they want:

• Pairing and control (when not responsive): Any HomeKit pairing and control issues could be because the Govee app cannot be open or running at the same time. I have to force quit the Govee app on my phone in order to get it to relinquish control to HomeKit. I hope Govee figures out how to remove this limitation, but I don't use their app so I don't care too much.
• Hard reset instructions: The Reddit thread (and Govee website!) have it wrong. To reset the device, you have to hold the Mode and Timer buttons for 5 seconds. This is mentioned on a little paper insert they included with the fan.
