The control of Hue lamps that are connected to a bridge works absolutely problem-free with Google Home. I cannot say whether it also works with Bluetooth Hue lamps.
Here are some commands:
"Turn on [name of the lamp]."
"Dim [name of lamp]."
"Increase the brightness of [name of luminaire]."
"Set the brightness of [name of luminaire] to 60 percent."
"Dim/increase [name of luminaire] by 30 per cent."
"Change the colour of [name of luminaire] to blue."
"Switch the lights in [name of room] on/off."
"Switch all lights on/off."
