I have the Roku Premiere and a Apple Mimi HomePod all setup with Apple HomeKit. A little disappointed I can’t get it to use the HomePod as the speaker. But my biggest issue is the Roku device does not turn off through HomeKit. You turn it off it turns back on in a few seconds. Turning on the television also. I’m considering putting it on a smart plug and just kill the power but then I have to wait to boot up. Wait if there are upgrades. There has to be a better solution.
