the reason you see two T/RH sensors is the S-2-3 sensor is a 2 channel sensor.  It has not one but 2 channels of T/RH.  It is shown on the web site as <sensor_id>:1 and <sensor_id>:2 with the “:1” and “:2” used to indicate which channel the data belongs to.  For the S-2-3, channel one is a plug in probe and channel 2 is the built in T/RH sensor.  If there is no probed plugged into to channel 1 it defaults to 32 degrees and you can safely ignore channel 1 data.
