Reverting zeroconf to 0.23 remediated this. The issue was on both mac and ubuntu(rasp pi)

Thank you for reporting this! I will add a note about it then.

I believe that updating to a newer pyhap should solve it (and would be a proper fix), but apparently some interfaces were changed after version 1.1.5, and unfortunately I don't have capacity at the moment to look into that.

But PRs are always welcome!
