Gree VRF Support

[vellad1]

Hi,

Tried the project but did not work for me and I am assuming it's because I have a Gree VRF system with 1 compressor and 4 internal units. They are exposed by a single IP.

I wiresharked the commans and what i foudn was that after the scan request {"t": "scan"} the JSON response has an extra field that seems to report how many internal units the unit has - the pack of the JSON return below:

{

			"t": "dev",
			"cid": "",
			"bc": "",
			"brand": "",
			"catalog": "",
			"mac": "b4430dd50fd2",
			"mid": "60",
			"model": "",
			"name": "格�空�",
			"lock": 0,
			"series": "",
			"vender": "",
			"ver": "",
			"subCnt": 4  (does this mean  it has 4 internal units)? seems to imply 
		}

The Gree Mobile App will then send the bind request as per the pack below:

{ "mac": "b4430dd50fd2",
"t": "bind",
"uid": 0
}

and return the unique key as per the below pack:

**{
			"r": 200,
			"t": "bindOk",
			"mac": "b4430dd50fd2",
			"key": "<UNIQUE KEY>"
		}**

The app then sends the JSON request below:

{"cid":"app","i":0,"pack":"huCTfZr+tmfrmjj5cppWoTuRTSHPH07rvUULx9II4CbtaD8c5Kb1s8De+taRtAFLGRthyav6ml/pLwGix91Arw==","t":"pack","tcid":"b4430dd50fd2","uid":1677840}

and the A/C responds with a JSON request with the pack below that clearly shows the 4 internal units that form part of the VRF.

**{
			"t": "subList",
			"c": 4,
			"i": 0,
			"list": [
				{
					"mac": "5259911b000000", 
					"name": "格�空�",
					"mid": "604b",
					"model": "",
					"lock": 0
				},
				{
					"mac": "fa7ad91a000000",
					"name": "格�空�",
					"mid": "604b",
					"model": "",
					"lock": 0
				},
				{
					"mac": "61fed31a000000",
					"name": "格�空�",
					"mid": "604b",
					"model": "",
					"lock": 0
				},
				{ 
					"mac": "dcecd31a000000", 
					"name": "格�空�",
					"mid": "604b",
					"model": "",
					"lock": 0
				}
			],
			"r": 200
		}**

From them on to get set command I will need to use the relevant mac of the sub ac for the A/C to work.

By any chance; are there any plans to support VRF systems? I would be happy to help with debugging etc. I don't use Home Assistant but can test via MQTT.

Thank you.
