HomePod can’t see any HomeKit accessories

Hello there,

I have a HomePod mini, and I setup 3 smart plugs connecting to HomeKit. It has been around 6 months since I got it, and it’s been working fine, controlling the plugs with ease. On morning though, I ask my HomePod, “Hey Siri, turn on the lights.” It replies by saying that it doesn’t see any HomeKit accessories. I tried to unplug it and plug it back in, and it still says that. When I go into my iPhone or iPad, I can easily go into the app and control the outlets. I have updated my iPad to iPadOS 15.1, and there is no available updates for the HomePod.

Thanks for any help in advance!
