Example

In this example, we are going to send toggle command to IKEA TRÅDFRI bulb using Xiaomi Aqara Wireless Remote Switch. To prepare, follow the steps:

1. Connect ZigBee stick cc2531 to USB;
2. Flash it using instruction: https://www.zigbee2mqtt.io/getting_started/flashing_the_cc2531.html;
3. Run the example;
4. Pair IKEA TRÅDFRI bulb by repeating 6 ONs and 5 OFFs one by one (ON -> OFF, ON -> OFF, ON -> OFF, ON -> OFF, ON -> OFF, ON);
5. Pair Xiaomi Aqara Wireless Remote Switch by holding the button for ~10 seconds until blue LEDs start blinking.

Now you can toggle the bulb using the remote switch. Just click on it.
