This integration uses the BlueFalls/Yoctub protocol:
- UDP discovery on port 12122
- TCP communication on port 12121
- Protobuf-encoded messages
- Ensure your spa is powered on
- Check that the spa is connected to your WiFi network
- Try pinging the spa's IP address
- Make sure no other app is connected to the spa (only one connection allowed)
- The spa requires a UDP wake-up before responding to TCP commands
- This integration handles this automatically, but network firewalls may block UDP
