Raw TP-Link (Kasa) command sender/receiver

Each invocation sends a single command and receives a single packet in response.

This program is a minimal substitute for the tplink-lightbulb Node package or a copy of Homekit. Because it's C, it's about 40x faster than the Node package. On a Raspberry Pi, that matters.

Building:
make

Usage:

  ./kasa <ip-address> <json-blob>
  ./kasa scan
  ./kasa-wrapper lamp off
  ./bulb dimmer 20\%

There's a good list of JSON blobs to try here:

Especially:

• get bulb info: ./kasa <ip> '{"system":{"get_sysinfo":null}}'
• turn bulb on: ./kasa <ip> '{"system":{"set_relay_state":{"state":1}}}'
• turn bulb off: ./kasa <ip> '{"system":{"set_relay_state":{"state":0}}}'
