Notes on pairing devices

Ikea light bulbs (tradfri) and switches (reddit)

For the bulbs you turn them off and on 6 times and then it starts blinking and just stop there, then it should be automatically discovered (at least it did for me with zigbee2mqtt).

For the remotes press pair button 4 times quick.
