Sure, but it still does cec. Specifically if you cast to it the TV turns on. I’ve only ever used my Google home to turn off the TV via “hey Google turn off the TV” but the functionality is there, there’s just no remote control to make it self sufficient

The old Chromecast does hdmi-cec for controlling the TV as well
