Abstract: The present disclosure provides a method for monitoring a network status of a Zigbee node. The method includes: acquiring a value of a status tag configured on the Zigbee node, the value of the status tag indicating a current network status of the Zigbee node; and determining that the value of the status tag equals a first preset value and a preset condition associated with the status tag is met. The first preset value indicates that the Zigbee node has joined a Zigbee coordinator but has not joined a gateway. The method also includes: in response to determining that the value of the status tag equals the first preset value and the preset condition is met, restarting the Zigbee node and resetting the value of the status tag to an initial value. The initial value indicates that the Zigbee node has not joined the Zigbee coordinator.
