"phantom" homekit commands?

Hi, recenly I’m having some weird “phantom” commands issued by Homekit - like turning on lights and TV at random times. Neither I nor my partner have issued these commands and there’s no automations set up in our Home apps at all. I see in Logbook these are issued by Homekit.

Any idea what this could be? Poltergeist integration? I do have iOS 15.4 beta (currently B4), anyone with the beta installed with similar experience? How do I debug this?

Did you ever figure this out? I’m experiencing the same issue with input_button entities.
