How to pair IKEA bulbs with ZHA ELELABS ZIGBEE EM358

A few questions.

  1. Are my ELELABS ZIGBEE EM358 even compatible with the IKEA bulbs?

  2. Is it possible to use the round IKEA tradfri remote control to pair the bulbs to HA, like when pairing to the IKEA Gateway?

  3. If option 2 is not possible, do i have to hold the USB ELELABS ZIGBEE close to the bulbs to pair? I hope not, since most of my bulbs are place 5 meter // 16 feet up in the ceiling.

I have 40 IKEA tradfri bulbs and 60 Philips Hue bulbs. As for now are paired with their standard gateways.

Thanks

Where you able to pair your IKEA bulbs? I have a Sonoff ZBBRIDGE and am unable to get my IKEAbulbs to pair with it and ZHA.
