I have sucessfullly connected my Samsung S7 phone with Google Asst to control my Iris, and the all the light switches work properly using Google Asst comands. However, my fan switch will not turn on using Google Asst. The icon next to the device in GA is a grey rectangle with 3 lines on the top of it. When I ask to have the fan turned on, it says that it is turning it on, but no reponse from the fan. It works fine using the online Iris controls.
I believe this is a Google issue. All of these controls work fine with Amazon Alexa voice control, but none of the fan switches work with Google Home devices.
