Im not sure what you mean by dealer model… you can get Elan from distributions around the country as an approved vendor so thats not a direct dealership no. You do have to be vetted in the same sense as other yes.
I have HA “beta” systems running for clients who really want to pull away from dealer based products but most of them are still using the major 3rd party options like Lutron, Sonos, ReoLink etc… its really a full time job and the service can be much more frustrating at times. There is only so much resetting you can do of a consumer product with someone else’s cloud credentials.
