I recently created a custom Google Assistant action that helps me manage my personal tasks. I also have a raspberry pi that can cast voice messages to my Google Home speaker. It basically notifies me when it's time to do a specific task. The action is capable of registering if I did this task or not. So after the voice message reminder is casted, I would like to respond to it immediately, so that I don't have to open the action myself with the default opening command (Hey Google, let me talk to 'My App').
I'm wondering if a raspberry pi is able to trigger the Google Home speaker to open an action. Or is it only possible to open an action by using the default opening command?
