The output node should give the option to the users to select the desired data to be obtained. By the moment the output node returns all the last information of the device, so if the user wants to get just the last value need to include a function node to parse the response in order to retrieve just the last value.

Just to give an idea the node can have a checkbox per each parameter, so the output can be modified with they need.
