JP1 Remotes

kk · Joined: 24 Dec 2003 Posts: 10

I am attempting to program my URC 8800 and Ratshack 15-2117 remotes to operate several Somfy/Harmonic Design System II motorized roller shades to open and close.

The shades operate via IR and came with a proprietary IR remote, however, when using their remote, it simultaneously sends a flashing red light with the IR command that renders the learning function of my other remotes useless.

Somfy emailed me the following two codes but I'm not sure what to do with them or if I should use IR, KM...

Can I use the following data to program my remotes via JP1 and if so, how???

1. KEY_UP_OUT - Immediate transmit of CODE_UP_LIMIT (0x08 + PARITY (0x40) )
2. KEY_DOWN_OUT - Immediate transmit of CODE_DOWN_LIMIT (0x09)

Any help is greatly appreciated!

You need more than that. You need a protocol, and a device code as well.

Not to sound too incompetent but...

Does protocol refer to (something like) NEC1?

Also, what does device code refer to since I am setting up a new device?

Thanks!

I'm the incompetent one, since I don't understand the post. But, to answer your questions:

Yes, NEC1 is a device protocol. Something like 0047 is a device code.

If you are going to make your own device upgrade, then you have to make up a device code (it can be anything you want between 0000 and 2047 but it's best if it doesn't conflict with one of the built-in ones (yours will override it for as long as it's in the remote)). You also may need to install a protocol for that device code (the protocol has its own ID like $003A). You can call that whatever you like, like NEC1. Again, the ID will override whatever's in the remote for as long as it's in there.

If your remote doesn't natively understand how to control your device, then you have to make a device upgrade, and probably a protocol upgrade as well. That's going to be really hard to do if you can't learn the code.

If that remote is actually breaking your learning remotes, I would give up. Now. If the OFA remotes can't handle it, they probably can't reproduce it.

If that's not the case and I'm just stupid, I'll let someone else step in to deal with all the details of protocol upgrades.

I'm not surprised the Somfy protocol doesn't work. The "Somfy" protocol is a hacked one-off protocol - to my knowledge never used outside of the one RM upgrade for Somfy window blinds that's in the file section - that works on my ancient (late 1970's) Somfy system, and to my knowledge there was never any demand for incorporating it any further.

If you're getting clean decodes, however, that should give you sufficient data to build your upgrade in EITHER KM or RM. Based on what you describe above, it should be working, but there may be something that you are NOT describing. The best way to proceed now is:

(1) Upload to the diagnosis area and post a link to the IR file with the LEARNED signals;
(2) Upload to the diagnosis area and post a link to the KM file you constructed on the basis of the decoded learned signals; and
(3) Upload to the diagnosis area and post a link to the IR file with the UPGRADE loaded that you uploaded to your remote and doesn't work properly.

...and someone will have a look.

P.S. Habit or not, I'd suggest giving RM a try before dismissing it as unwieldy.

The most important suggestion is #1 from the Capn, if we can see your clean learned signals, we can see whether they really are Akai or something else. Just verify that the learned signals actually work first.

If you must stay with km for this. Based on what you say the learned code shows up as, try efc 167, 164, and 039.
