How often will the discovery be called ? can we schedule it? When the [b]device is added to cloud[/b]. How should we notify that [b] discovery has to be done again.[/b]? While Discovery a device [b] may be reachable and after some time [/b] the device might not be reachable now is that to be changed ? can we send the update of the device data when we respond to turn on or off the device with its new info for that same device?
