Google Assistant is very aggressive when it comes to seeking out lights. They look at names as well as metadata. All lights are then treated as a group. I want to selectively expose dimmers to Google Assistant as a generic multilevel switch. I should still be able to say “Hey Google, living 50%”, but “Hey Google, light on” should not mess with my opt-out dimmers. I was able to accomplish this under SmartThings by avoiding the term light or dimmer in my names and choosing a switch for the icon (in SmartThings). When Google Assistant sees a switch they allow you to change the type under settings. So, you could make a switch a light. Unfortunately, you can’t make a light something else. My use case is that Google Assistant always manipulates more lights than I want. In fact, Google often gets confused and manipulates all lights in the house. That’s really bad at night-- especially if people are sleeping. My goal is to have a single light associated with each room even if there are other dimmers present.
