Ecobee4 Voice Engine

I just noticed the Ecobee4 has a VoiceEngine object. Has anyone taken a look at what is possible with this? It would be amazing to have this voice engine tied to the local HomeAssistant instead of Alexa or Google. Basically I would like it to be able to speak out alerts, or play a doorbell sound, and of course turn on and off lights.

Personally I’m not quite up to the task of taking on a project like this; I’m more of a programming enthusiast, not ready to tackle a new integration with an API.
