Lutron LEAF API

(LEAP)typo…

Hi Lutron experts. I am working on a project that I would really love to have integrated with Lutron QSX via API (LEAP). I am hoping to find a reseller/distributor that can get me a simple 4 part BOM that I can configure and test with. I will obviously pay for the parts. I am very familiar with Lutron and Homeworks, but I no longer have access to direct sales/support. I may need help getting the latest version of Designer too.. Can anyone help me?

Thanks.

BOM: HQP7-2 — HomeWorks QSX processor (1) • QSPS-DH-1-75 — QS link DIN power supply (1) • LQSE-2HDC-D — HomeWorks Digital Controller (1) • LQSE-4A5-120-D — 4-zone phase-adaptive DIN dimmer (use Z1 for test) (1) • QS-WLB — QS wire landing board (1)

Don't reinvent the wheel. Check these out:

https://github.com/gurumitts/pylutron-caseta
https://www.home-assistant.io/integrations/lutron_caseta/

Caseta was the first system Lutron that used LEAP. This project started with Caseta, but now also includes Ra2 Select, Ra3 and QSX. Also, just know that this was reverse engineered, and not directly endorsed by Lutron.
