|
|
I need help creating an upgrade file for my Amazon Basics 12-speed DC motor fan model B07BNK6T5Q
I get confusing learns with DecodeIR all with the same OBC and all with the DirectTV protocol but different devices as well as subdevices therefore I can't make an upgrade file.
With IRTransmorgifier I get no protocol so I'm at a loss of what to do here.
Anyway here is a link to the RMIR file
Thank You
EDIT:
Oh I forgot to tell the forum that it is on the "STB" button
Power = Power
Up Arrow = Speed/Timer up
Down Arrow = Speed/Timer Down
Left Arrow = Breeze Mode
Right Arrow = Timer
OK= Oscillate |

Happy X-Mas to all of you!!
Interesting. I looked at the signals, and it appears to be a new protocol. The learns appear to be quite consistent and noise-free, good. This is what I did:
Load the file in rmir. Turn on Options -> Advanced -> Learned signal Timing Analysis. Learned Signls -> Timing Summary. Save (as girr file, here fan.girr). In the IrpTransmogrifier distro, there is a xslt-script that takes that file to the named-input form of irptransmogrifier. So, (on Linux terminal)
Code: | $ irptransmogrifier decode --xslt contributed/input-filters/rawgirr2named.xsl --namedinput ../support/amazon_fan/fan.girr
Up: No decodes.
Down: No decodes.
OK: No decodes.
Left: No decodes.
Right: No decodes.
Power: No decodes. |
Right, it does not decode. So we try to "analyze"
Code: | $ irptransmogrifier analyze --xslt contributed/input-filters/rawgirr2named.xsl --namedinput ../support/amazon_fan/fan.girr
Up {38.5k,520,msb}<1,-3|1,-5>(9,-9,A:17,9,-9,B:16,1,-13.764000000000001m,9074u,-5,1,-52m,9074u,-5,1,-130m){A=0x544,B=0x2a2}
Down {38.5k,520,msb}<1,-3|1,-5>(9,-9,A:17,9,-9,B:16,1,-13.764000000000001m,9074u,-5,1,-52m,9074u,-5,1,-52m,9074u,-5,1,-130m){A=0x4b0,B=0x258}
OK {38.5k,520,msb}<1,-3|1,-5>(9,-9,A:17,9,-9,B:16,1,-13.764000000000001m,9074u,-5,1,-52m,9074u,-5,1,-130m){A=0x550,B=0x2a8}
Left {38.5k,520,msb}<1,-3|1,-5>(9,-9,A:17,9,-9,B:16,1,-13.764000000000001m,9074u,-5,1,-52m,9074u,-5,1,-130m){A=0x522,B=0x291}
Right {38.5k,520,msb}<1,-3|1,-5>(9,-9,A:17,9,-9,B:16,1,-13.764000000000001m,9074u,-5,1,-52m,9074u,-5,1,-130m){A=0x446,B=0x223}
Power {38.5k,520,msb}<1,-3|1,-5>(9,-9,A:17,9,-9,B:16,1,-13.764000000000001m,9074u,-5,1,-52m,9074u,-5,1,-130m){A=0x4a4,B=0x252}

which looks quite promising. So, possibly one of the executer wizards can write an executor for the protocol {38.5k,520,msb}<1,-3|1,-5>(9,-9,A:17,9,-9,B:16,1,-13.764000000000001m,9074u,(-5,1,-52m,9074u)*)?
IrpTransmogrifer can transmogrify even more:
Code: | $ irptransmogrifier analyze --xslt contributed/input-filters/rawgirr2named.xsl --namedinput ../support/amazon_fan/fan.girr --stat --parametertable --bit-usage
Timebase: 520.0

Here's how I see the signals:
I used
0 = +520 -1536;
1 = +520 -2588;
Up
+4500 -4500; 00000010 10100010 +500 -1500;
+4500 -4500; 00000010 10100010 +500 -14000;
+9000 -2500; +500 -52500; (repeats)
Down
+4500 -4500; 00000010 01011000 +500 -1500;
+4500 -4500; 00000010 01011000 +500 -14000;
+9000 -2500; +500 -52500; (repeats)
OK
+4500 -4500; 00000010 10101000 +500 -1500;
+4500 -4500; 00000010 10101000 +500 -14000;
+9000 -2500; +500 -52500; (repeats)
Left
+4500 -4500; 00000010 10010001 +500 -1500;
+4500 -4500; 00000010 10010001 +500 -14000;
+9000 -2500; +500 -52500; (repeats)
Right
+4500 -4500; 00000010 00100011 +500 -1500;
+4500 -4500; 00000010 00100011 +500 -14000;
+9000 -2500; +500 -52500; (repeats)
Power
+4500 -4500; 00000010 01010010 +500 -1500;
+4500 -4500; 00000010 01010010 +500 -14000;
+9000 -2500; +500 -52500; (repeats)
And here are the 6 buttons in binary format: Code: | Up 00000010 10100010
Down 00000010 01011000
OK 00000010 10101000
Left 00000010 10010001
Right 00000010 00100011
Power 00000010 01010010 |
In summary:
* You get the data signal twice, followed by a leadout time, then you get a data-less signal repeating. It's not unlike the NEC1 format.
the buttons on the remote are:
On/Off
Timer
Mode
Oscillates
Increase Speed
Decrease Speed
But as this is for a fan, and I see from the description that it has "3 power settings and 3 breeze modes (Nature/Sleep/Normal)", I suspect that the various modes are built into the signals, which would mean your UP and DOWN are really just the codes for the next speed selection.
To prove or disprove this theory, could you learn each button from the remote at least 3 times, and before you do, use the remote to put the fan into a known state (eg, you know which power mode and which breeze mode)
And in case anyone wants to see it, here's the user manual for this fan:

So the UP and DOWN buttons are true up and down buttons and don't just set the fan to a specific setting? Glad it works.
Could you tell me which of the factory functions you assigned to each of the buttons? I can guess 3 of them.
On/Off = POWER
Increase Speed = UP
Decrease Speed = DOWN
Timer
Mode
Oscillates _________________ Rob

Yes the up/down only do that function and don't set the fan to a specific setting
Anyway the full keymap is as follows
Power = Power
Up Arrow = Speed/Timer up
Down Arrow = Speed/Timer Down
Left Arrow = Breeze Mode
Right Arrow = Timer
OK= Oscillate |
