There are 2 integrations ...Option #1 and Option #2 ...per this link....
Option #1 is native Hubitat. The developer is no longer active in these forums but it works. It is the one I use with a Vista 20P. It uses Telnet and can be "chatty", so I use it on a separate dedicated hub.
Option #2 is used a lot. It is supported by @brianwilson . It does require a separate server like a Raspberry Pi.
