How long does it take for the firmware update to complete? Do I need to leave the Sengled Smart hub and Smart LEDs/Smart Accessories powered on?

Yes, you must leave the hubs, bulbs and accessories powered on.

However, you may set the bulbs or LED light strips to 0% brightness in the app if you don't want the lights to stay on. Do not turn the bulbs off via the wall switch. Do not turn power off to the accessories. 

The hub will usually update within 2-5 minutes; it may take longer since this is entirely dependent on your Internet speed.

The bulbs will usually update within 1-6 hours.

However, in some cases, the bulbs may take up to 12 hours to update.

If the bulbs have not been updated after 12 hours, please check to see if your internet connection is working properly.
