I have connected the device through xbee(cooridinator), started the server and sent the command to the device state as "ON".Now the light(item) which is connected to that device is turned "ON". When I disconnect the device and shutdown the server and then again restart it and connect the device back, the state of the light(item) is not resumed back to the previous state, as well as when I am trying to get the state of an item I am getting value "NULL".

What should I do if I have to get back the previous state of an item when I restart the server?

Whether the state of the item is persisted somewhere?
If so where is it persisted?

States can be persisted by adding a PersistenceService implementation and by feeding a PersistenceServiceConfiguration into the PersistenceManager.

ESH currently does not come with any persistence implementation - is as close as we got so far.
