ZigBee2MQTT light group

I’m trying to get two lights to work as parallell as possible. The lights are two hue light bulbs and integrated via Zigbee2MQTT.

If I create a light group in HA, they turn on/off in sequential order. (About half a second difference).
If I create a group in ZigBee2MQTT, they behave about the same.

I was hoping for a ZigBee group in Z2M would resolve this without success. Has anyone succeeded in getting ZigBee lights work in “parallell”?

How do you do that ?

Try a Zigbee group.

Sorry, I should have been more clear. I’ve made a Zigbee group in Z2M and get about the same performance. Previous post have been cleaned up
