I came across this on the Lutron Forum:
We wanted to highlight a few things about Integration with Lutron Devices. Specifically focusing on Telnet and LEAP.
Telnet for existing systems like RadioRA 2 and HomeWorks QS is not going away. Those integrations will continue work as they have.
The LEAP API is something that can be used with Caséta and RA2 Select and is necessary for HW QSX
LEAP is not just cloud integration, it can be local or cloud; common industry alliances in this market are all going local (C4, Crestron, etc)
Lutron is working with a wide variety of 3rd party companies for support of QSX LEAP integration. Most of the big name companies already have integration or have QSX integration coming in the very near future.
If there is a company or product that people would like to see us integrate with, they can email email@example.com and it will get evaluated by the business
We also wanted to add a few other additional reasons why LEAP is being used over Telnet. The first thing to emphasize is security with the TLS connection. Another benefit is that LEAP makes integration easier since most of the integrations auto extract the Lutron system config for you (no longer have to mess around with integration reports). One of the rare exceptions to this is Crestron SIMP, but companies like josh.ai and C4 pull in the config for the integrator to make it easy. This could be done in the past with Telnet and XML but LEAP config can be pulled dynamically vs an XML file that only gets compiled at transfer.
What I want to mine from this is exactly what it is that people are trying to control that they cannot and what is causing the grief on the forum. It is not clear to me in reading the thread if it is heartburn caused by Savant or if they really did make their own integration? In talking with many dealers over the years, I would be surprised by how many really made their own large scale drivers that are outside of the major manufacturers that already make drivers for the industry.
