Use this guide to update the firmware of a Sonoff ZBDongle-E Zigbee Interface for EMBER driver support.
EZSP drivers have been deprecated by Zigbee2MQTT and will no longer be supported. Because of this, we HIGHLY RECOMMEND upgrading your ZBDongle-E stick and changing to the EMBER drivers.
Requirements
-
Sonoff ZBDongle-E Zigbee USB Interface
-
Sonoff ember firmware v7.4.3 (or later)
-
A PC with free USB A port
-
Chromium-based web browser
-
HomeSeer users: HomeSeer Zigbee Plus plugin v 1.0.3.0 (or later)
Procedure
Note that the screenshots below show v7.4.3 and are for information purposes only. Your screens will display a newer version than that.
-
Download the ZBDongle-E firmware and save it to your PC.
-
Navigate to https://darkxst.github.io/silabs-firmware-builder/
-
Click the purple CONNECT button under the image of the ZBDongle-E
-
In the dialog box that appears, select the SONOFF dongle and click the blue Connect button.
-
Once the software connects, click CHANGE FIRMWARE.
-
On the next screen, select the option to upload your own firmware and select the file previously downloaded to your PC.
-
Click INSTALL. The upgrade process will take a bit of time to complete. Wait for this to finish.
-
Upon completion, this dialog will appear. Click CONTINUE
-
The updater will once again connect to the stick and a final dialog box will appear that displays the firmware version on the stick.
-
The firmware upgrade is complete. We recommend power-cycling the stick by removing and then reattaching it to the USB port.
