Not sure what went wrong but Homekit is not working on my ATV 4K. It was initially and now I can't get it back. On my iPad I can fully control my homekit devices via Siri. Ive got TFA on and am using the same icloud account on both iPad and ATV. I see the ATV device under devices in the icloud settings on the ipad. However Siri on tvOS says nothing is connected. Upon first setup it was all working well, but I think I updated the Hue app and since then it only worked with some things. It lost track of rooms. So while I could say turn off all lights, it would work, I couldn't say turn off basement lights. Or turn of "specific" light. I had an outlet, and could say turn on/off amplifier and it understood "whats my temperature" from the ecobee, but I couldn't get it to give me the basement temperature from the sensor there. Ive tried logging out of icloud on atv and ipad (much more of a pain to do on the ipad). I did a reset of the atv and I am just not seeing homekit under icloud settings on tvos.
