Control and monitor Tosot/Gree air conditioners via WiFi with automatic error recovery.

• 🔍 Device Discovery - Automatically find AC units on your network
• 📊 Status Monitoring - Check power state, temperature, modes, and more
• 🎮 Full Control - Turn on/off, set temperature, view all parameters
• 🔧 Auto Recovery - Automatically detect and recover from AC errors
• 📝 Error Logging - Track all errors and recovery attempts
• 🐳 Docker Support - Run easily in containers

docker run -d \

# Clone the repository
git clone https://github.com/emielvangoor/tosot-ac-watch.git
cd tosot-ac-watch

# Build the control tool
go build -o tosot-ac-control main.go

# Build the watch daemon
cd watch && go build -o ../ac-watch main.go

# Scan for devices
./tosot-ac-control scan

# Control specific device
./tosot-ac-control status gang
./tosot-ac-control start gang
./tosot-ac-control stop gang
./tosot-ac-control temp gang 22

The watch daemon monitors the AC for errors and automatically recovers:

# Run the watch daemon
./ac-watch

# Run in background
nohup ./ac-watch > ac-watch.log 2>&1 &

Edit main.go to configure your devices:

devices := map[string]struct {
    MAC string
    IP  string
}{
    "gang":      {"f4911ef6d9bf", "192.168.1.223"},
    "woonkamer": {"f4911ef82651", "192.168.1.222"},
}

The watch daemon:

• Monitors AC status every minute
• Detects error codes automatically
• Stops and restarts the AC on errors
• Restores previous temperature settings
• Implements rate limiting (max 2 restarts per 5 minutes)
