I think its now impossible to use the Hue Emulation with Google Home. I removed it on mine after months of perfect working, and when i tried to set it up again i also got redirected to the meethue.com site. I tried old versions of the GHome app which worked for some others, but not for me.
So if its working for anyone - dont remove it!
