Is it always possible to re-configure the network after resetting or unbundling?

Not necessarily, this depends on the strong and weak binding relationship of the device. 1. Strong binding: the user must first unbind the device from the App before the next person can operate the network; the advantage is safety, the disadvantage is the operation is troublesome, currently some devices of IPC and door locks choose to use strong binding, some ease of operation can be sacrificed for safety. 2. Medium binding: The level is slightly weaker than the strong binding. After the local reset, the previous bound user will not be removed, and the next user can also configure the network, but will send a push and message center to the previous user to notify the previous user; Between strong and weak binding , only one more notification than weak binding. 3. Weak binging: It is the weakest binding level which has the largest percentage. The device can be reset and bound by another user at will, without the consent of previous user, and no notification to previous user.
