Old Lutron before Intercative Module

RicardoSiqueira Junior Member

January 2014 in Residential Forum

I am looking for any help with a possible module for the old Lutron Homeworks System, before interactive or Illumination. I got a protocol from Lutron, but I am wondering if anyone have a module for it. I have the task to integrate this old Lutron System with Netlinx, but of course our sales team didn't sell enough hours for me to try to create a module for it. Lutron provided the attached protocol. I am just wondering if anybody out there has a module for it or sample code. The button emulation is very straight forward, but the LED feedback is very tricky.
Thanks,

Ricardo

I haven't controlled an original Homeworks with anything more recent than an Axcent, and then I just sent the strings hard-coded to the processor. My usual method was to make a few virtual keypads in the Lutron for the Axcent to emulate. I didn't do feedback since I rarely used two-way panels in those days, but if you limit your functions, it shouldn't be too hard to open up a terminal to the Lutron and see exactly what comes back, then base your feedback on that. If they aren't willing to pay for a full-blown module, that may be the best way in any case.

I just wrote one for an ancient system I worked on 3 weeks ago that does loads with feedback and normal button pushes I can send to you, if that's all you need.

true,

Yes please send it to me. It will save me a lot of time trying to come up with something for a job undersold. I appreciate your help very much.

How to convert HEX to bite

Thanks true for sending me your module. Now, I am trying to see if I can do the LED Feedback. Do you guys know how to covert a HEX number to bits and store it on an array? Here is a sample of a probable LED feedback string:

'L101A2BD',$0D,$0A

L1 = LED feedback for panel 1
01 = Keypad 1
A = HEX value for LED 13 to 16 - 1010 (LED 13 is On, 14 Off, 15 On and 16 Off)
2 = HEX value for LED 9 to 12 - 0010 (LED 9 is Off, 10 Off, 11 On, 12 Off)
B = HEX value for LED 5 to 8 - 1011 (LED 5 is On, 6 Off, 7 On, 8 On)
D = HEX value for LED 1 to 4 - 1101 (LED 1 is On, 2 On, 3 Off, 4 On)

The ideal would be to be able to store this on a structure or array that we could hold the PANEL, KEYPAD and all LEDS, so we could assign a TP channel # to the LED current status of 1 or 0.

Something like: [Panel][Keypad][0000000000000000]

Any ideas?

Thanks

For what it is worth, I spent last night playing with the protocol and I was able to design a structure and response parsing to handle the LED feedback. It is not very pretty, and I am sure there is better ways to handle this. But it is working with the testing strings so far. I haven't tried it in the field yet. The old Lutron LED feedback comes in in an ASCII HEX values in a reverted format, so to make it easier to reference in code and assign to a TP channel for feedback, I changed the orientation on the structure. Instead of storing LEDS 16-13, 12-9, 8-5, 4-1 as Lutron sends them. I am storing them in the 1-4, 5-8, 9-12, 13-16 order. I am also using true's module to process the sending strings. In the structure I am also holding the original ASCII HEX values so it is easier to see them converting to 0101 format. See attached the complete include file.
