Gateway very slow in signaling lights

I have about 16 Cree bulbs connected to my gateway. The gateway is very slow in changing light statuses; sometimes changes to lights happen immediately - whether on or off - other times it can take up to 5 minutes before the change is signaled to the light.

Any suggestions about how to troubleshoot or fix this?

Thanks for the tip. I’ll have to research how to change the channel on
the Zigbee and I’ll try this.

I did realize that your Cree bulbs may be wifi? But if they are zigbee It certainly could benefit by trying to get interferance away. IF you use wifi 2.4ghz Its probably best to go for an non overlapping channel, 1,6 or 11(at least in my country) as far as possible away from the zigbee frequency. Im using wifi channel 6 and zigbee channel 25. Works perfect.

Yes, my bulbs are Zigbee. I haven’t had a chance to try this fix yet but I hope to soon.
