With Android 11 now out in the public (I got it today), it offers some pretty sweet integration with the Hubitat.
First some basics:
While Google Home only thinks about controlling "physical" things like lights, thermostats, etc., with Hubitat, you can create VIRTUAL Switches--which Google Home thinks are just simple light switches.
What's cool about that is that Hubitat lets you trigger any actions you want based upon the switch moving on/off/changing, (or a dimmer level if you are using a virtual dimmer). And, you can make rules based on the status of those switches. Since they are virtual, there's no cost, wiring, or odd lamps going on and off in the corner of the room!
So, now, you can develop nearly any automation you want and trigger it directly by turning one of those virtual switches on/off or you can control the behavior using "IF xxx is ON THEN" logic in rules.
To tie this to Google Home: by letting Google Home have access to that virtual switch, you can just tell Google to turn it on/off. It may think it's turning a light on/off, but really the Hubitat is doing what you programmed it to!
Say, your Mother in Law visits occasionally and you want to get the guest room ready, you could have a "Mother in Law Mode" switch. When it's on, her room temperature is adjusted, the lights are turned on, etc.
When she arrives, you can just say "Hey Google, Turn Mother In Law Mode On"--and things will work fine.
Now, little does she know, but you have some other rules you've written. One that will change the temperature by 10 degrees hotter then colder every hour. Another that randomly flashes the bedroom lights every 20 minutes or so, etc. Those are only triggered when the "Time to Go" virtual switch is turned on.
Now, when you're ready for the Mother In Law to leave, a simple "Hey Google, Turn Time to Go on". And, your automations will kick in, making for an inhospitable time.
With those concepts in mind... on Android 11, you can put any of those "mode" switches (along with any real ones) right on the new "Home" panel!
When you do a "long press" of the power button (longer than a "click"--but not so many seconds as to cause a forced reboot--say, about 1 second), you'll get a pop-up screen that lets you power off, lock down, choose a credit card or---WOOHOO!!! Turn selected lights on and off via Google Home!!
By clicking the three dots next to that, you can chose which switches (or virtual switches) you want to appear. Then, after that, you can click the 3 dots and "edit' their position.
Now, you can can have your favorite automations at your fingertips--and you don't even need to start an app!!
For the sake of harmonious family relations, here are some ideas that might be more palatable to your spouse:
TV Mode - Adjust the lighting in the TV room for ideal viewing. Possibly even turn on the TV and stereo. When this switch is turned off, it resets the lights for normal activities.
Asleep Mode - Turn off all the lights. close the garage doors, lock all the outside doors, and turn on the porch light. You might have this one automatically reset to "Off" (turning it on will trigger those actions, so it doesn't necessarily need to stay on).
Good Morning Mode - Turn on the morning lights (slowly for tired eyes) and get ready to go. Like Asleep Mode, you might have this one toggle itself off.
Lock Up the House Mode - Lock all the outside doors and shut the garage doors. This is another one you might have turn itself off automatically.
Essentially, whatever helps you out!
Once that's all set up, you can just tell Google what you want--or, with Android 11, you can just squeeze the power button for a moment then click the action you want without making a peep.
Pretty cool stuff!
