Header Space and Mark Timings for Gree YAC #117

Open cmroche opened 3 years ago

cmroche commented 3 years ago

This references work done for #86 . I've been able to make this work in practice using an ESP8266 with an SHT30 temp sensor, pinging the heatpump approx every minute to update the temperature.

In doing this though I actually couldn't get it to work with the default provided timings.

Using IRrecvDumpV3 I did a differential comparison of the raw results from the YAC1FBF remote, and a test rig I built using arduino-heatpump to transmit (basically transmitting and demodulating on 1 halves of a breadboard). The results showed notably different timing resutls.

This is from the YAC1FBF remote

But using arduino-heatpumpir I am getting these results (the results are highly repeatable over many samples, also ignore the JVC decoding, we're only interested in the RAW output):

It's a big discrepency in kHdrMark and kHdrSPace between both samples.

When I make this change though to arduino-heatpumpir to more closely match my remote it suddenly started working.

Old timings:

// Gree timing constants
#define GREE_AIRCON1_HDR_MARK   9000
#define GREE_AIRCON1_HDR_SPACE  4000
#define GREE_AIRCON1_BIT_MARK   620
#define GREE_AIRCON1_ONE_SPACE  1600
#define GREE_AIRCON1_ZERO_SPACE 540
#define GREE_AIRCON1_MSG_SPACE  19000

This is what I am using now:

#define GREE_AIRCON1_HDR_MARK   6000
#define GREE_AIRCON1_HDR_SPACE  3000
#define GREE_AIRCON1_BIT_MARK   650
#define GREE_AIRCON1_ONE_SPACE  1600
#define GREE_AIRCON1_ZERO_SPACE 540
#define GREE_AIRCON1_MSG_SPACE  19000

However I only have 1 specific Gree device, so I'm wondering if this represents a change in Gree timing perhaps requiring us to treat this like a whole new protocol, or if the Gree timings are just wrong.

Juhani-H commented 3 years ago

I also have one "Gree" copy or compatible device ("Wilfa Lillehammer 10/9" marketed in Finland) and these are MY LIRC raw-mode decoded values, that i use to control my device.

So i think this is maybe some "new protocol".

Somewhere(on the internet) i found this value list, Type: Gree35_67AC / Altname: CUSTOM23 / Header: 9000 / HeaderSpace: 4500 / Mark0: 600 / Mark1: 600 / Space0: 600 / Space1: 1690 / Carrier: 38000 / Delta: 200 / Syntax: HB035TB032T,HB035T / Marks: 600,600,9000,600,0,0,0,0 / Spaces: 1690,600,4500,0,0,0,0,0

All other (functions) will work on "default" values, however i can't turn my device OFF, some in this library there is somerthing wrong with that.

cmroche commented 3 years ago

Just to clarify, the sequence you posted is coming from your remote right? What is "LIRC decoded values" (I'm not sure what LIRC means in this context).

cmroche commented 3 years ago

@Juhani-H Ping ^^

Juhani-H commented 3 years ago

Hi, yes sequence is coming from remote (YAN-?1F1?). Lirc decoded values i mean that these are the raw measured values (no decoding used, only measure time between pulses), device that i used was Raspberry Pi2 + "LIRC"-program lirc.org),

So in my data it shows that values should be around:

define GREE_AIRCON1_HDR_MARK 9051 - 9071 avg. 9060

define GREE_AIRCON1_HDR_SPACE 4000 4420 - 4482 avg. 4450

define GREE_AIRCON1_BIT_MARK 700-720 avg.710

define GREE_AIRCON1_ONE_SPACE 1598 - 1642 avg. 1615

define GREE_AIRCON1_ZERO_SPACE 497 -527 avg. 500

define GREE_AIRCON1_MSG_SPACE 19898 - 19925 avg. 19909

Thanks;

I think this explains what is happening. The main message and the IFeel message, even if sent in sequence are acting like two completely different protocols, with their own HDR_MARK and HDR_SPACE timings. If you keep decoding you will notice about every 5 minutes the remote resends a much smaller messages similar to just this, which uses 6000 for HDR_MARK, and 3000 for HDR_SPACE. Trying to use the 9000 and 4000 defaults for this message will cause it not the be readable by the AC.

6087 | 2935 | 706 | 497 | 709 | 499
707 | 499 | 708 | 1600 | 707 | 1600
706 | 493 | 712 | 499 | 707 | 499
708 | 1601 | 709 | 500 | 706 | 1593
714 | 497 | 708 | 498 | 707 | 1604
707 | 498 | 707 | 1596 | 712 |

The default values of 9000 and 4000 will work for the main state message, and align with the values lirc computed for you.

Juhani-H commented 3 years ago

Wow, i just found that your right, last section that my first posted sequence is actually IFeel part.. because if i look without IFeel function, that 6000 ---> part is missing..

Probably my receiver didn't get complete message (IFeel-part), only part of that.. because my all timings that has IFeel ON are like this.. 6088 2929 713 1600 708 500 706 499 717 1586 712 1600 706 499 708 497 709 499 706 1596 713 500 707 1601 707 499 706 499 708 1593 713 498 708 1614 695

Any info about how to decode the IFeel sequence? or where is the CLOCK/TIME signal? (or is it only in REMOTE, so AC doesnt get it).

But still almost all functions are working with default values, but OFF and "WINTER" mode doesn't work.. But if i sent those with Raspberry and IR-led those work..

Any clues why it wont work..?
