I’ve integrated it via ADB, and that’s working, but there’s a several-second lag between something happening on the Shield and its State updating in Home Assistant, so I’m trying the Google Cast integration in the hope it’ll be better.
But it won’t even show that my Shield is turned on. I’ve added it, entered the correct IP, reserved that IP in my router’s DHCP settings…it’s still greyed out on my dashboard and listed as “off” in Developer Tools->States.
