How do I get the TRÅDFRI bulbs back in sync if they have lost connection?
Light sources can become out of sync when you interact with the main power switches (wall or lamp switches) with part of your connected light bulbs.
For example, when you turn OFF one light bulb in a group with the main power switch and change the rest of the light bulbs in the group to another state, the turned-off light bulb will be out of sync when turning it on again with the power main switch.
You can watch the films below for guidance on how to sync your bulbs:
