JP1 Remotes

[mikemcgo]

Hi. I was hoping I could decode some learned codes and create a device upgrade for my fan. I was able to do it for a few Sony codes for my DVD player, but I'm stuck with these. Can anyone help me? I've uploaded the file, it is at:

Thanks,

Are those learned codes all from the fan? If not, could you state which buttons are from the fan.

Hi. Yes, they are all from the fan. It is kind of a weird remote. It only has 7 buttons, but the remote keeps track of the current state. The speed button toggles between four speeds, so it took four buttons to learn its functions.

Thanks,

Here is how I decode those commands. They have two or three bytes seperated by a long gap and another two or three bytes:

These are MSB first and all bytes are 8-bits:

B1 B2 B3 B4 B5 B6
23 65 73 23 61 73 last
0B 61 73 XX XX XX c-
23 65 73 XX XX XX move
0B 60 77 XX XX XX c+
23 63 73 XX XX XX freeze
XX 1A 4D XX 1A 10 0
XX 1A 44 XX 1A 01 1
XX 1A 45 XX 1A 02 2
XX 1A 44 XX 1A 03 3
XX 1A 45 XX 1A 04 4
XX 1A 44 XX 1A 05 5
XX 1A 45 XX 1A 06 6
XX 1A 44 XX 1A 07 7
XX 1A 45 XX 1A 08 8
XX 1A 4C XX 1A 09 9
XX 12 21 XX XX XX info
XX 12 61 XX XX XX mute
XX 12 A1 XX XX XX pip
XX 12 E1 XX XX XX swap

BTW, what is on the numerals?

For anyone familiar with John Fine's new irp format here is a rough guess at what it uses:

{27.4k,500,msb}<4,-2|1,-5>(6,-1,1,Byte1:8,Byte2:8,Byte3:8,3,-70,1:1,Byte4:8,Byte5:8,Byte6:8,3,-70)

{27.4k,500,msb}<4,-2|1,-5>(1:1,Byte2:8,Byte3:8,3,-70,1:1,Byte5:8,Byte6:8,3,-70)

{27.4k,500,msb}<4,-2|1,-5>(1:1,Byte2:8,Byte3:8,3,-70)

We can probably create:

{27.4k,500,msb}<4,-2|1,-5>(1:1,Byte2:8,Byte3:8,3,-70) in PB and use macros for the additional segments for the two byte commands and
{27.4k,500,msb}<4,-2|1,-5>(6,-1,1,Byte1:8,Byte2:8,Byte3:8,3,-70) for the one time three byte commands

The remote has a timer button where it can be set to turn off in 1 to 10 hours. The numerals contain these timer commands.

Thanks,

Mike,

What are the other commands. The last time I decoded a fan, it pretty much worked in 4-bit commands. That is 16 possible setings for each nibble (0 to 9, plus A,B,C,D,E, F). This one looks like it may do the same thing.

You mentioned a toggle between blower speeds would that by any chance be the bottom four commands in my list. If we can come up with a plausable theory, about what these bytes mean, I'll create a protocol or two and you can test them out.
