The newest alternative is HubConnect.
If you’ve never used HubConnect, the guide points to that how-to and after that detour, you install HubConnect for HA on your Home Automation system.
I took a fully reset Hubitat hub, downloaded the two HubConnect bundles, installed HubConnect and then added a Connect a Hub. I filled out the form, pasted the connection key to my freshly built HomeAssistant VM. Then completed the Hubitat Verify step. Done.
Although I do have plenty of experience with these Packages, it took under 5 minutes to do.
A couple minutes later I had selected a Hubitat device and mirrored it to HA.
This test was created to verify the instructions, not get something production ready. I have that running on my other Hubitat Hub and other HomeAssistant VM
