Updating the Firmware of your Hub and Bulbs

Firmware is software that is installed into the hardware of a device. In this case, it is a way to ensure that your hub and bulbs are running at the latest and greatest version. Firmware makes the smart bulbs and hub smarter.

The Sengled Home app will let you know when a firmware update to your hub or bulbs is needed. There will be a red dot next to the “Settings” tab in the bottom right corner on the “Home” page of the Sengled Home app.

Do not press the reset button on your hub.

To update your firmware, press “Settings” located at the bottom-right corner of the “Home” page. Then press “Firmware Upgrade”.

Please note, “Firmware Upgrade” on the “Settings” page also has a red dot next to it indicating a firmware update is needed.

From here, you will be on the “Firmware Update” page. Notice the devices that need an update have a red arrow next to them. The devices that have the latest firmware do not have a red arrow next to them.

Press “Upgrade All” and then “Upgrade” to update the firmware of your hub and/or bulbs.

Please note that a hub can take two to five minutes to update. After the update is complete, the hub will turn off and be offline in the Sengled Home app temporarily to install the update—much in the same way a computer will restart after an update. The speed of the update is dependent on the speed of your internet at the location the hub is being used in. Be sure to keep your hub powered on during the update.

Bulbs take one to six hours to update their firmware but can take as long as twelve hours. Be sure to leave the bulbs powered on from the light fixture they are being used in during firmware updates.

While the hub is updating its firmware, you may not be able to control the bulbs as the hub will reboot itself during the update process.

While the bulbs’ firmware is updating, controlling the lights may be on a slight delay. You can still use the bulbs in the meantime.

Now, the hub’s firmware is updating.

You do not have to stay on the “Firmware Update” page of the Sengled Home app while your hub and bulbs are updating their firmware. Once the command to update the firmware of your hub and bulbs is given, you can navigate away from the “Firmware Update” page by pressing the back arrow in the top-left corner.

Note: The seemingly long time for bulbs to update firmware is since they use the ZigBee HA protocol to communicate. The ZigBee HA signal does not carry as much data as WiFi. ZigBee HA devices, however, have a much greater reach than WiFi devices.
