Support for SRK25ZC-S

[sergioperez]

Hello,

I have a Mitsubishi Daiya SRK25ZC-S, which does not seem to work correctly with any of the current implementations (tested via https://esphome.io/components/climate/climate_ir.html#heatpumpir)

At the moment, I have recorded the following input from the remote (address 0x4A75, aeha protocol)

25 cold eco on 0xC3,0x64,0x9B,0xFF,0x00,0xF8,0x07,0x6E,0x91
25 cold eco off 0xC3,0x64,0x9B,0xFF,0x00,0xF8,0x07,0x7E,0x81 (poweroff action)

24 hot low 0xC3,0x64,0x9B,0xFF,0x00,0xFD,0x02,0xC1,0x3E
24 hot hi-pow 0xC3,0x64,0x9B,0xFF,0x00,0xFC,0x03,0xC1,0x3E

24 cold eco (airflow nomove) 0xC3,0x64,0x9B,0xFF,0x00,0xF8,0x07,0x61,0x9E
24 cold eco (airflow move) 0xC3,0x64,0x9B,0xFF,0x00,0xE8,0x17,0x61,0x9E
24 cold eco (airflow down) 0xC3,0x64,0x9B,0xFF,0x00,0xF0,0x0F,0x61,0x9E

The pattern that I see at the moment, it's:
bytes:
[0]: 0xC3
[1]: 0x64
[2]: 0x9B
[3]: 0xFF
[4]: 0x00
[5]: [Fan mode / Power mode]
[6]: opposite of 5
[7]: [Mode(Cool/Warm/Humidity) / Temperature]
[8]: opposite of 7

If I manage to get the time, I will try to implement a PR to control these AC units. Any comments or hints are more than welcome, as I have not too much idea about what I am trying to do :)

Hi @sergioperez, did you end up making any progress on implementing IR for this unit? I have a very old SRK56HAA which I assume is similar in protocol. The remote part number is RKS502A503D.

Hello @nickw444! Not at all, I just implemented this (far from ideal) workaround in ESPHome to test it, but I did not end up using it:

Thanks, I am thinking I will do something similar, the work involved in decoding the protocol seems too high when I could just do what you have done and repeat captured states that I am interested in. Thanks for sharing.
