[2.0] Creation of AI Assistant Knowledgebase

[strawgate]

We should create an AI Assistant Knowledgebase -- perhaps compiled using our docs or perhaps separate that allows us to easily ask the AI Assistant questions like:

"Is my Front Door unlocked?"
"What is my thermostat set to?"

[legrego]

I like this idea. If only we had a unified knowledge base to plug into, then we wouldn't have to decide which of the soon-to-be 3 assistants to target 😛
