As a smart home hub, Google Home (and Mini and Max as well) is pretty great but tracking down the list of partners can be hard, now Google has added a support site with an easy to find list of each and every device supported.
The list has every partner that supports Google Home, and the product that can be used with Google Home. In addition to first party devices that support Google Home, you’ll also find devices supported by third-party Actions on Google services. The list of devices is searchable by device type: Lights, Locks, Plugs etc. or you can hit the ‘Narrow by’ box on the right of the search bar, but that’s simply a list of manufacturers that you can also see by scrolling down the list.
It’s a good resource for all smart home devotees so check it out and find out which devices you can get to automate your house.
