I also have a QSX system. I have access to the Crestron QSX modules that have the DLL files in it for communicating. if someone smarter than me can decompile the file using something .NET Reflector, they could probably get the required key from the DLL so we can talk to QSX systems. Also Radio RA3 will become more prominent now as well which will likely be the same communication using secured LEAP instead of telnet.

I think there is a misunderstanding here ! There is no special key to connect at QSX. It’s just an SSL connection so you basically at first generate a CSR and generate an SSL key that you’ll use for secured communication with processor. I have checked the AMX module for QSX and there is no secret key in it, just mention that first time module connects at QSX it’ll take around 15 minutes for AMX processor to generate the SSL keys !

I haven’t done my QSX upgrade yet, but that will be done within the next few weeks. Their LEAP communication is relatively new,

Have you succeeded to get it working ? Being a Lutron dealer I have contacted them to get the protocol to be able to develop integration for it but they are so old fashion and so bad view of home automation market right now They refuse to release protocol for open system and considering HA not enough mainstream

I have not really tried to do some deeper technical digging yet - but without Lutron opening the API up its likely not possible.

I have a direct channel into Lutron and talked with a high up in charge at Lutron. Here is his response to open the LEAP API up:

[…]

As far as your concerns, I wanted to do my best to respond to you in the best possible manner.

• Our main focus as it relates to our custom residential systems products like Homeworks QSX is on ensuring a quality integration experience through a high-quality and well-qualified integration company who is designing and building the entire system.

• We understand that there are people who know what they are doing and can use brands like HA to create a great experience. It sounds like you are one of those customers. We do however remain concerned about the vast majority of other non-Lutron dealers and end customers who may lack the required knowledge and skills necessary to ensure a great integration experience.

• As it relates to your feedback about Caseta Wireless:
• Caseta Wireless can be fully DIY whereas our Homeworks systems are meant to be designed and installed by professional integrators.

We certainly understand and respect your concerns. However, HomeWorks isn’t intended to be a system with DIY integrations. We will definitely keep your input in mind as we look to expand our base of alliance integration partners in the future.

If not reverse engineered by someone this won’t be opened up for business $$$ reasons.

Has someone tried using their HomeKit interface to integrate with Home Assistant?

I’m interested in delivering a professional integration experience with Home Assistant. My company installs Home Assistant and Lutron as a service.

What would it take to reverse engineer the API? Is that possible? I have a client that might pay for this.

Don’t bother about it, Lutron integration in HA supports properly QSX processor now (I have one running at a customer site since few months now) although stupid Lutron company doesn’t want to support non commercial home automation systems (but what to expect from a company that is using 100% Microsoft ecosystem to develop its products…).
Side note: Lutron integration configuration is so simple ! You just fill IP of QSX processor and after 1/2s it asks you to push the button on the processor and you are done

[dts]

Can you elaborate? Which integration of the Lutron component is applicable for QSX? Lutron Homeworks?

[vincen (Vincèn)]

First remove any custom components you might have installed for Lutron in your HA, reboot HA and then go into Integrations Menu → Lutron → Lutron Caseta, fill processor IP, it’ll ask you after few seconds to push the tiny button on processor to confirm the link and you are done (Lutron Caséta - Home Assistant)

Works great, thanks
