### API Endpoints



#### AC Control

```

GET /set?mode={mode}&temp={temp}&fan={fan}&swing={swing}&model={model}

```



**Parameters:**

**Examples:**

```bash

# Set model to Daikin (model 4) and turn on cool mode at 24°C

curl "http://accontrol.local/set?model=4&mode=1&temp=24"



# Use saved model (Daikin) for subsequent commands

curl "http://accontrol.local/set?mode=1&temp=22"

## Troubleshooting



### WiFi Issues

1. **Can't connect to setup network**: Check if device is powered and LED is blinking

2. **Configuration portal not working**: Try visiting `http://192.168.4.1` directly

3. **WiFi credentials not saved**: Use `/reset?erase=1` to clear settings and try again



### AC Control Issues

1. **IR commands not working**: Check IR LED connection to GPIO 33

2. **Wrong temperature**: Verify your AC supports the temperature range

3. **Mode not working**: Check if your AC model supports the selected mode



### Device Issues

1. **Device not responding**: Check power supply and USB connection

2. **Web interface not loading**: Try accessing via IP address instead of hostname

3. **Serial output**: Connect via USB and check Serial Monitor at 115200 baud
