New to Onn 4K and Google Home

I have all HomeKit at home (use Homebridge for a pretty broad mix of devices, but Homekit/Siri) as the only interface. I use Alexa at my office. I had never uttered the words ‘Hey Google’ before this weekend.

I grabbed an Onn 4K Pro for the garage and it seems really cool. I‘ll have to admit I was pretty shocked when I said ‘Hey Google, set a timer for 10 minutes’ and it couldn’t do it. Seems a really basic function for a smart speaker; even if it is primarily a tv box.
