iHome
1) Can you use iHome app with android devices ?
2) My wife was invited to my iHome and I did not send her an invitation nor did I even know I had iHome, how could this happen?
Your question is too vague to answer. iHome is a 3rd party company. They are NOT Apple. Android is a platform developed by Google. It has nothing to do with Apple.
So far, you have not posed an Apple related question.
You need to clarify what's going on. If you're asking if the Apple Home app is compatible with Android, the answer is no.
If you're trying to ask something else, you need to explain it.
