### Register Gateway Event Listeners

Source: https://github.com/egeback/aiomihome/blob/master/README.md

Sets up callback functions for heartbeat and device data events from the gateway. The 'data' argument in callbacks contains the received information.

```python
async def heartbeat_callback(data):
    print("HEARTBEAT RECIVED", data)

async def device_callback(data):
    print("Device data RECIVED", data)

gateway.heartbeat_callback = heartbeat_callback
gateway.device_callback = device_callback
```

### Auto-discover Gateways Configuration

Source: https://github.com/egeback/aiomihome/blob/master/README.md

Configuration for auto-discovering Xiaomi gateways. Ensure the 'key' variable is defined.

```python
gateways_config = [
    {
      "host": "10.0.4.104", 
      "sid": "7811dcb07917",
      "port": 9898,
      "key": key
     }
]
service = XiaomiService(gateways_config=gateways_config)

# Start the mulitcast socket listner
await service.listen()

# Run the auto discover
gateways = await service.discover()

print("Number of gateways found: {}".format(len(gateways)))

# Get first gateway
gateway = gateways[0]
```

--------------------------------

### Directly Connect to Gateway

Source: https://github.com/egeback/aiomihome/blob/master/README.md

Establishes a direct connection to a specified Xiaomi gateway. Requires the gateway's host, port, SID, and key.

```python
service = XiaomiService()

# Start the mulitcast socket listner
await service.listen()

# Create a gatewate connetion
gateway = await service.add_gateway("10.0.4.104", 9898, "7811dcb07917", key)
```

--------------------------------

### Control Gateway Light Color

Source: https://github.com/egeback/aiomihome/blob/master/README.md

Sets the gateway's light to different colors (red, green, blue) sequentially, followed by turning it off. Requires an active gateway connection.

```python
# Red
await gateway.set_color(255, 0, 0)
await asyncio.sleep(1)
# Green
await gateway.set_color(0, 255, 0)
await asyncio.sleep(1)
# Blue
await gateway.set_color(0, 0, 255)
await asyncio.sleep(1)
# Off
await gateway.turn_off_light()
```

--------------------------------

### Print Gateway Device Information

Source: https://github.com/egeback/aiomihome/blob/master/README.md

Iterates through the gateway's known devices and prints their types, counts, models, and data. This snippet assumes 'gateway' is an initialized Gateway object.

```python
print("Turn on light")
for device_type, devices in gateway.devices.items():
  print(device_type, len(devices))
  for device in devices:
    print("     ", device['model'])
    print(device)
      for value_key, value in device['data'].items():
        print("         ", value_key, value)
```

--------------------------------

### Close Gateway Connections

Source: https://github.com/egeback/aiomihome/blob/master/README.md

Closes all active connections managed by the XiaomiService.

```python
await service.close()
```
