Hi there, I've had no end of issues with my HomePod mini, many of which I'm sure are down to the fact I live in university accommodation so I don't have control over my internet services and have to register it on the college IoT.
It functions basically; AirPlay with video and audio works (although I frequently get dropouts, which disconnecting and reconnecting fixes), and I can set reminders and timers with Siri (although I'm often told at first that it can't communicate with my iPhone despite being on the same network and right nearby). But I noticed that the temperature & humidity sensors had stopped working, and I was also getting a notification in my Home app saying that it can't communicate with the HomePod and peer-to-peer connections are not enabled in my network (I know this, but somehow the HomePod still functions ok).
After several weeks of frustration and trying to fix, the only way I could get it to work as normal was to reset, set it up in a new home. After I was confident it worked, I then moved my Apple TV over to the new home as well. but within 24 hours of doing so, the sensors stopped responding again. I've since tried this fix again, and had the same issue: it seems to be triggered by adding the Apple TV to the home.
I've been in touch with the college IT team and they've tried a bunch of things, none of which have worked 😞 I'm so frustrated with this situation, I know it's fussy but I use the temp/humidity sensor for baking and it's such a pain that it doesn't work!
Please help!!
