 Before upgrading any OTA firmware, it is recommended to install fresh batteries in the device. OTA firmware updates are power-intensive, and some devices check for a minimum battery level before starting the upgrade. These devices may refuse to initiate the update process if the battery level is too low. However, not all device firmware includes this check.
 
-If Zigbee firmware upgrades do not start on a Zigbee End Device (i.e. a battery-powered product), then note that you usually need to "wake up the device" (e.g. trigger state change or pressing a button if available) so that the device becomes awake and are thus able to receive commands to start the OTA upgrade. The reason for this is that battery-powered products are so called "sleepy devices", so they normally they are askeep and only receive commands when the state of the device is changed.

The reason for this is that battery-powered products are so called "sleepy devices," so they normally are asleep and only receive commands when the state of the device is changed.
 
 If the upgrade still does not start, then try manually restarting the device by disconnecting the power/battery for a few seconds and try again; then again make sure to activate the device by triggering state change or pressing a button on it right before sending the update request. Try to push a button on the device (if it has one) shortly before you start the firmware update to wake it up. Sometimes, it also helps to try keeping the device awake by repeatedly pushing a button pr triggering state change until you see the first "Updating... " message in the user interface.
