Once the user authenticate the BOND smart action with Google Home the Fans that were programmed will show up on the Google Home app as a switch and light ( as two device)
This is due to the fact Google Home does not support yet ceiling fans - a device that has speeds and also a light or two.
The Name of these devices is derived form the names the BOND user used in the BOND app.
If the name of the Fans in the BOND app change they will not propagate to the Google HOME. In order to do it the user has to unlink the BOND action and relink it again.
