Send IR commands
- Uses IR Raw protocol without signs.
- Pairs of numbers, first is positive (ON), second is negative (OFF).

- Use irgen to convert IR codes to
raw. (compatible with Broadlink) - Use IrScrutinizer for advanced analysis of IR codes.
- Use irplus LAN 📱 to send IR Raw commands. 📺 Use URL:
http://${SPEAKER_IP}/ir - Pending: Create LIRC server implementing something like broadlink-bridge
