This iPad Can No Longer View This Home
I ran into this issue today. I'm not sure how long it has been happening since I haven't used the Home app in a long time:
I took this image from App Home - Apple Community but it's effectively the same as I am seeing. I updated iOS to 15.7.8 on an iPad Air 2. I reinstalled the Home app as suggested but the issue persists. I suppose I could do a factory reset to revert to an older version of the app. However, after everything updates, I'd be back in the same position so I'm quite hesitant to try that.
The Home app seems to be suggesting the issue is software and not hardware. The App Store says under Compatibility: "Works on this iPad".
Why does this error occur? How do I resolve it?
