Older silver Hue bulbs don't want to play

I’m in the process of moving all my devices to Home Assistant Green using a Sky connect dongle and Zigbee2MQTT. Everything has moved over without too much of a fuss, with the exception of my 4 older Hue bulbs that have the silver base. My newer Hue bulbs with the white bases have been fine, but these silver varieties have not wanted to pair with Zigbee2MQTT. Does anyone have any experience with these older bulbs?

Not sure if it works with your SkyConnect dongle, however if it does you might try the ‘TouchLink’ function if you have not already done so. Good Hunting!
