Can the coordinator remotely change the Listen Window in endpoints?

No we do not allow coordinators to dynamically change the listen window for endpoints. The reason for this is that a sleepy endpoint is typically battery powered and dynamically extending the listen window in the field could unexpectedly and significantly reduce battery life. The listen window can be changed at the endpoint and finished endpoint products (such as battery powered sensors) will have the listen window set according to the needs of that application. When we create custom endpoints for clients, we set the listen window according to the needs of the system and will factor into our battery life calculations.
