The plugin keeps everything it knows about the devices (collected during pairing, then updated while running) in an internal structure, ListOfDevices. It is saved regularly, not in real time:
DeviceList-<hardware id>.txt of the plugin Data folder (<hardware id> is the Domoticz hardware ID of the plugin), and, when the expJsonDatabase setting is on, in a DeviceList-<hardware id>.json copy;useDomoticzDb and storeDomoticzDb settings are on (the default). At start-up the plugin reads the most recent of the two.To look at the database, use the WebUI: Tools > Tools, Plugin Raw Devices (see Use the plugin tools).
The fields are described in Structure of ListOfDevices.
