It looks like you haven’t set up any home kit accessories
Overnight the Siri on my two home pod minis no longer recognize all the accessories. All worked when I went to bed last night but this morning the HomePods no longer control lights or any accessories. All is the same in the home app and Siri on my iPhone still works well.
I have added no new accessories and there have been no changes prior to this situation. It literally happened overnight.
I have tried rebooting my phone and unplugging my HomePods.
Has this happened to anyone else?
