Home Assistant Green Integration

I purchased a Home Assistant Green device a few days ago in hopes that I can use that device to create/run dashboards but still leave the automation and devices within Hubitat. Unfortunately, I am stumped as to how to get the devices over to Home Assistant from Hubitat. Is it possible for HA Green? If so, does anyone have step-by-step instructions on how to do this?

Hopefully I didn't waste $$$ in purchasing the HA Green..

Can Home Assistant Green use HACS? Which allows third party addons.

I set this up on a a Docker instance of HA to play around with the dashboards.

Update: Looks like you can get HACS on there, I found a post where someone was asking about it and they got it working. Here are the docs on getting HACS, which I think you need to get the addon I linked above.
