I have 3 Hisense Roku TVs. At some point, 1 TV appears to be perpetually offline in my Google Home. I compared configurations with the working Roku TV and they are identical. I've tried unlinking and relinking Roku with Google Home, and even doing a complete factory reset of the Roku TV, followed by unlinking/relinking, but still the device appears offline in Google Home:
Device not responding. Make sure it's on and connected to Wi-Fi.
In the process of all the unlinking and relinking, my 3rd Roku TV is now offline and won't respond either, breaking my Google routines. They all work fine with the Roku remote, both on my phone and with the physical remote.
What can I do to make it work?
