[OBSOLETE] Original & Aqara Xiaomi Zigbee Sensors (contact, temp, motion, button, outlet, leak, etc)

It is pretty simple.

  1. In the My Home tab of the SmartThings “Classic” mobile app, press the + icon to “Add a Thing”, putting your hub into pairing mode.
  2. Put the WXKG03LM into pairing mode, by holding its button down until the LED at the bottom flashes. There are two revisions of the WXKG03LM, the 2016 revision and the 2018 revision. Depending on which revision you have, you will need to hold the button down for either around 5 seconds or around 15-18 seconds. Either way, it has gone into pairing mode and you can release the button when the LED flashes rapidly a few times.
  3. Wait for the LED to flash again. If you see one long flash, it is paired. If it blinks a few time, pairing was unsuccessful, and you need to put it into pairing mode again (go back to step 2).
  4. Wait for the device to appear in the SmartThings “Classic” mobile app, ready to be renamed and used.

If you cannot pair the button in 5-6 attempts, then please see this post for more information about why Xiaomi / Aqara devices can have pairing / connection issues:
