Cree bulbs not working

[WB70]

@pmcdonal

Yesterday morning I woke up to all 5 of my Cree bulbs unresponsive and Offline.

Simply unplug and remove the batteries from your hub and leave unplugged for a few minutes and then plug it back in and put in the batteries.

To ensure that a Zigbee Heal commences, you need to leave the ST Hub unplugged (and batteries out) for at least 15 minutes (to make sure I would just unplug for 30 minutes). The devices will go into panic mode after a period of time and when the Hub comes back online, a Zigbee Heal will then be performed.

1. Heal the zigbee network

Healing a zigbee network is easy. Just take the smartthings hub off of power for at least 15 minutes while leaving all the other Zigbee devices turned on. Take out the batteries from the hub if it has any as well.

The zigbee sensors and bulbs will all go into “panic mode” as they realize the Coordinator (the smartthings hub) is not available.

Then when you put the hub back on power, each individual zigbee device will rebuild its own neighbor tables. It can take a while for this process to finish, so you may not see improvements until the next day.

A fortunate secondary effect of the hub being offline for 15 minutes is that it will then re-sync with your cloud account.
