Daikin AC OFF not working in Daikin Remote ARC484A4

[rahul121190]

Hi @crankyoldgit . I hope you are doing well.

I have a Daikin AC unit which uses the remote ARC484A4. The model ARC484A4 corresponds to protocol DAIKIN (280 bits/35 bytes), and hence I am using the IRDaikinESP class to send the IR signal and it works when I try to turn ON the AC. However it does not work when I try to turn OFF the AC. I have currently stored the raw value for the Off command for the remote and using the sendRaw method in IRSend to make it work.

I managed to get the IR Dump data of my remote as well as the one generated by the library file. Below are the IR data captured via IRrecvDumpV3. I see a difference of 9 bytes between the code generated by library and the remote.

AC OFF
0x11DA2700C50010E711DA27004200005411DA270000382800A0000006600000C18000B9 (via Remote Control)

AC ON

Is there any way I can make the AC OFF to work using the library.

Thanks in Advance

For reference, could you also give us the model number of the A/C Unit?

What does IRrecvDumpV3 show as message when you use the off command?

We can sure make this work, but might need some more data before we can pin-point the needed changes

AC OFF

Okay, breaking this down as I go.
0x11DA2700C50010E7 ... That's the comfort bit. So the remote is set with comfort on, and DaikinESP class hasn't had that set. That difference can be ignored.

The last byte is a checksum, so that can be ignored.

That leaves the "middle" 4 bytes that are different.

The second last different byte (i.e 80 vs 00) is the weekly timer. So that can be ignored. i.e. Remote has the weekly timer on, the class has it off.

The 3rd last different byte (C1 vs C0) is unknown to us. That is, we don't know it's function.

The 4th last different byte is vertical swing. It's just in a different position. (e.g. A0 vs 30)It can be ignored,

And the 5th last different byte is the temperature, it too can be ignored. (e.g. 28 vs 34)

So that, leaves byte[31] (C1 vs C0) as the culprit. How does this behave with other commands from the remote?
We/you need to find out why your remote has it as C1 instead of C0. e.g is it always C1 etc.

[crankyoldgit]

FYI, you don't need to use sendRaw(), you can use sendDaikin() instead.
e.g.

const uint8_t remote_off[kDaikinStateLength] = {
    0x11, 0xDA, 0x27, 0x00, 0xC5, 0x00, 0x10, 0xE7, 0x11, 0xDA, 0x27, 0x00, 0x42, 0x00, 0x00, 0x54,
    0x11, 0xDA, 0x27, 0x00, 0x00, 0x38, 0x28, 0x00, 0xA0, 0x00, 0x00, 0x06, 0x60, 0x00, 0x00, 0xC1, 
    0x80, 0x00, 0xB9}; // (via Remote Control)
irsend.sendDaikin(remote_off, kDaikinStateLength);

[NiKiZe]

Correct me if I'm wrong but it is also possible to set the raw state to toggle the bit/byte and still have it in the class?

[rahul121190]

@NiKiZe & @crankyoldgit : Thanks for the quick response. I stepped out for some work. Once I get back, I will check if the byte[31] behaves the same way for other commands from the remote.

    0x11, 0xDA, 0x27, 0x00, 0x00, 0x38, 0x28, 0x00, 0xA0, 0x00, 0x00, 0x06, 0x60, 0x00, 0x00, 0xC1, 
    0x80, 0x00, 0xB9}; // (via Remote Control)
irsend.sendDaikin(remote_off, kDaikinStateLength);

Sure will use sendDaikin going forward.

[crankyoldgit]

Yep, Correctl That byte, if set via setRaw() should persist until another setRaw() or stateReset().

I was going to suggest that as a possible workaround, but if that single bit is just some model identifier it will be an easy enhancement. (Famous last words)

[NiKiZe]

For that we would like to confirm that that bit is set in everything that the remote sends? (yes that is what you wrote)
Does the remote have any kind of id setting under some cover that can change? (but odd that everything works except off)

No. The remote does not have ant dip switch under the cover (unlike my other Daikin Remote BRC4C151 for DAIKIN176 has one, and @crankyoldgit fixed it via setId/getId.)

@crankyoldgit : Looks like the byte[31] does not change no matter what buttons I press on the remote. I tried changing the mode/temperature/fan speed/swing/timer/turbo etc., but still byte[31] remains the same. Attaching the IR Dump data for various buttons pressed in the remote.
