New Version Of Gree AC cannot connect HA

hemingfei commented 4 years ago

My old four gree AC （https://detail.tmall.com/item.htm?id=600728625205&skuId=4369182830517） is now OK to link with HA,

I bought a new version of gree （ https://detail.tmall.com/item.htm?id=626652028213 ） this year, and it is ok to connect to the gree's APP, now using the HA and this component, it cannot link.

I saw some relevant git, is that help to improve? https://github.com/cmroche/greeclimate and https://github.com/home-assistant/core/pull/42616

I have 5 gree ACs, 4 is OK. the last one cannot connect HA, it is the bought this year and maybe is a very new version. Reproduces are the same as the 4 ok ACs. It can be controlled by the Gree's APP.

Bug: the new Gree AC cannot connect HA

Configuration:

platform: gree name: 'Living Room AC' host: 192.168.0.111 port: 7000 mac: 'F4-91-1E-F8-F0-F0' target_temp_step: 1

I am trying to implement the encrypt and decode msg, and then see the details. the key and ways I can found in your script. but im not very familiar with python, so im trying to implement in window C# console to see the details of the json.

RobHofmann commented 4 years ago

The AC times out. This usually means that either something on your network is blocking communication or the configuration is wrong (wrong IP or wrong port).

hemingfei commented 4 years ago

In my situation, its a new problem , I tried discovery and bind. the new AC can be discovered but cannot bind. Maybe the key chagned. I test using windows console. 格力王者

some part of the code after the log "Binding":

log.LogDebug(" Binding");

            var bindRequestPack = new BindRequestPack() { MAC = deviceInfo.ClientId };
            var request = Request.Create(deviceInfo.ClientId, Crypto.EncryptGenericData(JsonConvert.SerializeObject(bindRequestPack)), 1);
            var requestJson = JsonConvert.SerializeObject(request);

            var datagram = Encoding.ASCII.GetBytes(requestJson);

            using (var udp = new UdpClient())
            {
                var sent = await udp.SendAsync(datagram, datagram.Length, response.Address, 7000);

                if (sent != datagram.Length)
                {
                    log.LogWarning("  Binding request cannot be sent");
                    continue;
                }

                for (int i = 0; i < 50; ++i)
                {
                    if (udp.Available > 0)
                    {
                        var result = await udp.ReceiveAsync();
                        if (result.RemoteEndPoint.Address.ToString() != response.Address)
                        {
                            log.LogWarning($"  Got binding response from the wrong device: {result.RemoteEndPoint.Address.ToString()}");
                            continue;
                        }

                        var responseJson = Encoding.ASCII.GetString(result.Buffer);

                        responsePackInfo = JsonConvert.DeserializeObject<ResponsePackInfo>(responseJson);
                        if (responsePackInfo.Type != "pack")
                        {
                            continue;
                        }

                        var bindResponse = JsonConvert.DeserializeObject<BindResponsePack>(Crypto.DecryptGenericData(responsePackInfo.Pack));

                        log.LogDebug($"  Success. Key: {bindResponse.Key}");

                        foundUnits.Add(new GreeBlynkBridge.Database.AirConditionerModel()
                        {
                            ID = deviceInfo.ClientId,
                            Name = deviceInfo.FriendlyName,
                            Address = result.RemoteEndPoint.Address.ToString(),
                            PrivateKey = bindResponse.Key
                        });

                        break;
                    }

                    await Task.Delay(100);
                }
            }
        }

        log.LogInformation("Scan finished");

        return foundUnits;
    }

the other four old gree AC can be discoverd and bind success.

do you have the ways to get the GenericKey? (old: "a3K8Bx%2r8Y7#xDh")

RobHofmann commented 4 years ago

There are several ways to extract the key. NOTE: I dont use this myself, but other people have done this. One of the methods is in the readme: https://github.com/RobHofmann/HomeAssistant-GreeClimateComponent/blob/master/README.md

Another way: https://github.com/RobHofmann/HomeAssistant-GreeClimateComponent/issues/64#issuecomment-646510604

Found another comment about retrieving the key.
