Help with Lutron Grafik eye

[terence8888]

I'm trying to get Lutron Grafik eye 3000 series working with my JP1. Found some CCF code but got stuck at the very first line because the protocol shows 0000 which I cannot get from keymap-master.

Am I doing something silly?

Thanks in advance!

Here's the decoded CCF:

The DecodeCCF output you're getting indicates that DecodeIR doesn't recognise the protocol.

Did you find that CCF file online somewhere? If so, post the URL for the CCF file so we can examine it ourselves.

There was a lot of discussion of the Grafik eye in remote control forums a long time ago. I forget the details of what we determined, but I think I remember that we solved whatever issues were being discussed. So I think a search of some remote control forums should provide your answers, maybe even a JP1 upgrade.

I found it here: lut-light-grafikeye.zip

I looked at the download section and could not find the upgrade. Any help much appreciated!!!

Did you try this upgrade:

Thanks for the replies. I tried this upgrade and it works to some extent: i.e. "scene 1" works; "scene 4" activates 2 and "scene 7" activates 3. None of the other works correctly though the grafik eye reacts to it and switches into some sort of "default" setting.

I tried to decodeccf other ccf files and I always get 0000 as the protocol. Does it mean that the information it spills out is useless?

Any ideas?

Cheers!

The first 4 characters of a Pronto hex string are almost always zeroes, which means it's a raw learned signal. When you need to analyse raw Pronto hex, it's better to use the old CCF2EFC program instead of DecodeCCF as it will give you the complete hex string (note: I belive that DecodeCCF can also give the full string, but I think you need to go into command prompt mode to do it, I don't know how to make it work with drag & drop).

However, CCF2EFC can't handle CCF files that were created for the ProntoPro (as is the case with the file that you linked to), so here's a different file created for the old Pronto: lut-light-grafik.zip.

I should warn you in advance though that this is a fairly complicated signal, so it won't decode that easily. Did you also try the upgrade files for the "Space Dimmer" to see if they work with the graphic eye?

I think you need to go into command prompt mode to do it, I don't know how to make it work with drag & drop

I suggest using the context menu (right click on the ccf file). It is easy to setup up and then easier to use than either drag/drop or command prompt and lets you fully customize the command switches.

I should warn you in advance though that this is a fairly complicated signal, so it won't decode that easily.

Did you find a decent desription of the protocol (preferably in IRP notation) so I won't need to redo that work when I add DecodeIr support?

Where did that executor come from? Did you code it?

[The Robman]

Nope, wasn't me, I've never delved into the Lutron discussions before now. The code for the Graphik Eye is an official UEI code (HOME/0597) and the one for the Spacer appears to be custom code which I think was written by Jon Armstrong. Some of Jon's posts at Yahoo seem to imply that the Spacer and the Graphik Eye uses the same protocol. I didn't find an IRP description of the protocol in my searches.

The Mitz 740 code seems to have been written by Alain and Jason (according to this thread)...

Here are some other hits that I got searching...

It turns out that all the Lutron upgrades use the official UEI executor.

I found a good spreadsheet of Pronto hex codes for Lutron over at Remote Central that was put together by Lutron themselves. I've been studying the signal and there don't appear to be any burst pairs, it looks like the ONE pair has zero off time and the ZERO pair has zero on time, and this is how UEI implemented it also.

The signal is 36 bits long. The first 8 bits are always ONE, so this can be considered the lead-in. The last 4 bits are always ZERO, so this can be considered the lead-out. Which leaves 24 bits of data.

If there is a checksum-like relationship between any of the data bits, I can't find it. However, I have noticed a pattern in the format of the data. Each nibble only has the following 8 possible values:

0001 0111
0010 1101
0100 1011
1000 0111

(ie, 4 values and their compliments)

The UEI executor uses 4 bytes of fixed data. The first byte is truely fixed, this is used to format the first 8 data bits. Bits-0 and 1 of the 2nd variable byte are used to select whether the 2nd, 3rd or 4th fixed byte is used to format the next 8 bits and the variable byte is used for the last 8 bits.

The UEI executor also seems to do some other funny stuff which I haven't bothered to really try and follow. My guess is that this is the same sort of BS that they added to the X10 exec to make it hard to learn.

Terence, do you have a learning JP1 remote? If so, could you learn the buttons from your Lutron remote and then post the results in the Diagnosis Area, then post a link to the file here.

[The Robman]

I have written a new, MUCH simpler, executor for the LGE that I'd like you to try out.

Here's the KM file...

If it works, I'll post upgrade files for all the other Lutron devices.
