Google Home

Devices known to AutomationManager can be made available through Google Home, allowing voice and other Google Assistant actions.  See AutomationOnDrive for adding AM devices to Google Home.  (Note, the integration service in the Google Cloud so a small subscription fee is charged to fund the service). 

In AutomationOnDrive you select the devices you would like to make available in Google Home.  Some devices types can be changed to allow different behaviors.

Note: needs AutomationManager 16.13.3 or later and AutomationOnDrive 5.0.4 or later.

Troubleshooting

Google Home Types

Garage Doors

A garage door control is often triggered by an event to open/close a garage door.  Caution is advised as a garage door should only be closed when it is in sight to avoid accidents.  It's also advisable to avoid triggering the door to open if it is already open (e.g. by repeating the open command) as this could cause it to close accidentally.  If you have a sensor for the garage door state a better approach is to use AM automation events to control it.

Now when you say "Open the garage door" the event will only be triggered if the door is closed.  Similarly a close command will only trigger the door event if the door is open.  The door flag will follow the state of the sensor so you can ask Google whether it's open or closed.

Routines

Google routines provide a mechanism for you to trigger AM actions and scenes using any phrase you desire.  I am reluctant to rely on the internet & cloud for important sequence of actions, so sequences or multiple actions may be better implemented by creating rules fired by events using OnEvents triggers that then runs the actions within AM.  Then use AoD to expose the event to Google Home as a Scene or Device.  In the google home routine I can start that scene (event) by voice with "Start" or as a device (switch) with "Set" or use it a Google Home routine and trigger with any phrase.  If for some reason my home is offline I can still trigger it from my phone via AM with a single touch.
