Add support VRF Air Conditioning

[a007007007csy]

After I turned the [Xiaomi Gateway 3 Firmware Lock] switch on, the gateway seems disconnected from the Internet. No matter how I change the Firmware Lock status or restart the gateway, it's always offline in the Mi Home app. So I couldn't connect to any of BLE devices without the Internet right now.

Devices:

1. ZNDMWG03LM (Chinese version, US plug): v1.4.4_0003 factory firmware -- Cannot work in MiHome App while controlled by HA
2. WXKG01LM -- Working fine
3. Xiaomi TH Sensor 2 (LYWSD03MMC) -- Not working

1. You have some problems with Xiaomi cloud.
2. Maybe 1.4.4_0003 have some problems, I don't know. Update to new supported version. Check list in readme.
3. BLE don't work without connection to cloud on original firmware

@AlexxIT Thank you for your useful advice. By testing, my Xiaomi_gateway3, Zigbee devices, and BLE devices are all successfully connected to HA, the gateway could working with HA and MiHome APP simultaneously! Now my gateway's firmware is v1.4.5_0016, This can be confirmed that v1.4.4_0003 was not well supported, you could inform guys on the readme page.

Here's a VRF air condition controller that supports connecting to MI Home App with Zigbee protocol. Now the device can be recognized in HA, I'm still in testing.

Xiaomi Gateway 3
New device:
did: lumi.<>
mac: <>
model: lumi.airrtc.vrfegl01
version: 1
zb_ver: 1.2

@a007007007csy is it support VRF now?

[AlexxIT]

@superwangmeng No. If you have it - enable logs in integration options. Control device in different ways and send this logs to me.

全网都没有适配这个设备的插件,homekit controller也只能控制关闭空调,打开完全没反应~

I got my VRF air conditioning controlled by AlexxIT gateway3 module first get devices count from 13.1.85 then control AC by 14.[1-count].85

eg: my 13.1.85=7 so i have
14.1.85 14.2.85 14.3.85 14.4.85 14.5.85 14.6.85 14.7.85 i can read write my 7 AC by these mi spec

hvac and fan enum vaules: hvac = {HVAC_MODE_HEAT: 0, HVAC_MODE_COOL: 1, HVAC_MODE_DRY: 3, HVAC_MODE_FAN_ONLY: 4} fan = {FAN_LOW: 0, FAN_MEDIUM: 1, FAN_HIGH: 2, FAN_AUTO: 3}

first read: _raw = self._raw = data["_raw"] self._enabled = True if _raw >> 28 == 1 else False self._attr_fan_mode = list(self.fan.keys())[list(self.fan.values()).index(_raw >> 20 & 0xF)] self._mode = list(self.hvac.keys())[list(self.hvac.values()).index(_raw >> 24 & 0xF)] self._attr_target_temperature = _raw >> 8 & 0xFFF

then write: _raw = self._raw power_val = _raw >> 28 hvac_val = _raw >> 24 & 0xF fan_val = _raw >> 20 & 0xF temp_val = _raw >> 8 & 0xFFF extra_val = _raw & 0xFF

if "climate" in value: power_val = (1 if value["climate"] else 0) elif "hvac_mode" in value: power_val = 1 hvac_val = self.hvac[value["hvac_mode"]] elif "fan_mode" in value: fan_val = self.fan[value["fan_mode"]] elif "target_temp" in value: temp_val = int(value["target_temp"]) _raw = power_val << 28 ^ hvac_val << 24 ^ fan_val << 20 ^ temp_val << 8 ^ extra_val

then we can read write power & hvac mode & target temperature & fan mode last 8bit maybe it's swing mode, i will figure it out later

actually, this device can also use http get to obtain status and send commands. This method has limitations because there's not lan port aside rs485 panel, I use a network bridge to connect vrf controller into home network. Finally I use nodered to send/obtain commands. The powerline networking adapter maybe another choice.
