Lutron integration?

[CE_Michael]

Hello, I am considering using Loxone but am wondering how it integrates with Lutron lighting systems (RA2 or HWQS)?  I've contacted Loxone tech support but they seem intent on discouraging this in favor of their proprietary lighting system.  Has anyone had any experience with this combination or insight on how it might turn out?

If you're unfamiliar with Lutron it uses IP communication preferably, but RS232 is also an option.

Do you have any documentation on its IP communication protocol?  If not, then I wouldn't suggest trying it.  If you do, then a proper feasibility assessment is possible.

Full integration protocol for reference if anyone is interesting in digging in.  Pages 46 to 51 should provide most of the relevant information.

The key points I believe are:

To help create and manage the different integration operations, three distinct operation characters have been selected to begin each command. All protocol messages will start with one of the following operation characters:

 # Execute an action (e.g., turn a dimmer on/off)

 ? Query system information (e.g., determine on/off status of a dimmer)

 ~ Monitor responses from the system when requested or after a change has occurred (e.g., if someone turns on a dimmer locally, a response command is sent out to indicate the change)

Output Command Format

#OUTPUT, Device ID, Action Number, Paramaters

Example

#OUTPUT,2,1,70,4,2

Set output level on device #2 to 70% (fade 4 seconds, delay 2 seconds).

~OUTPUT,12,1,100.00

This is the string that is sent by Lutron when device #12 is set to 100% (fade 0 and delay 0 are optional and omitted).

So Loxone would have to establish a telnet connection with the Lutron processor and then be configured to send the strings, or react in a particular way when it sees the relevant string.

Michael, I have seen customers and Loxone Partners talking to Lutron Systems both over IP and over RS232. We (Loxone) did not try or test it ourselves, as we obviously work with our own lighting solutions that offer seamless integration and controls within our product line at a great price. Shoot me an email and I may be able to connect you to one of our partners that did Lutron integrations before. Florian

This looks like it would be doable, although picoC may be necessary.

Chack out my project https://github.com/sushilks/lutronjs, it gets you a bidrectional-integration between loxone and lutron Caseta products.
