One app to rule them all !!!
All devices in one view: You can keep track of everything in one place without needing to flip between apps. The Home app organizes your devices by room so that you can easily control your speakers, lights, cameras, TVs and more than 10,000 connected devices that work with your Google Assistant. That means there are more than 200 million devices that can be controlled with your voice, many of them already in your home. Just note that controlling devices like a thermostat or lights requires smart thermostats or smart lights.
You can also connect other apps to the main google home app such as NEST and SMART LIFE.
Now, everyone under the same roof can control smart devices in your home, they just need the Google Home app on their phone. That means one app to get it all done—add, remove and control devices. We also added a feature for those of us who are on call to answer tech questions for our less-savvy family members that lets you control multiple homes. That means you can manage your parents’ home or help that cousin who’s having trouble setting up their smart home.
we have selected our devices carefully and tested them to make sure they all work well from one single app to make controlling your smart home easy and one tap away.
