== Introduction ==
Cumulus provides some support for extra sensors that can be connected to Oregon Scientific (e.g. WMR-928) and Davis (e.g.Vantage Pro 2 wireless models can have extra sensors whose readings can be interrogated via the Davis DLL) weather stations. Please note, this is nothing to do with certain [[EasyWeather_Format#Note_on_Models|Fine Offset models]] including solar and UV sensors.
'''NOTE:''' This article may need to be updated by somebody who actually has and uses such instruments. From what I have seen in the support forum, the OS weather stations can support up to 10 temperature and humidity measurements, so that has determined the Cumulus provision. The Davis DLL may be able to cope with up to 8 such sensors, so it will never update all the fields available in Cumulus.
=== General customisation ===
You can associate the extra sensors with descriptive labels using [[Strings.ini#Extra_Temperature_Captions.2C_Extra_Humidity_Captions.2C_Extra_Dew_Point_Captions.2C_Soil_Temperature_Captions.2C_Soil_Moisture_Captions.2C_Leaf_Temperature_Captions.2C_and_leaf_Wetness_Captions| modifying extra sensor labels in strings.ini]].
=== Oregon Scientific customisation settings ===
For Oregon Scientific WMR-928 weather stations, the ''WMR928 extra channel captions'' frame on the '''Display Settings''' screen within the ''Configuration'' menu allows you to change the captions displayed with values for 3 extra channels (see [[Strings.ini#Extra_Sensor_Captions]]). For WMR928 stations (and other stations using the same protocol, e.g. WMR968) to use an 'extra' channel as your main temperature sensor, set N to the required channel by adding an extra line ''WMR928TempChannel=N'' parameter to the [[Cumulus.ini#Other_weather_station.2Finstrument_specific:|Station section of cumulus.ini]].
== Extra Sensor Log Files ==
If ''Extra Sensors'' is set in the settings frame on the '''Station settings''' screen off the configuration menu, files are automatically created with names in the form <tt>ExtraLogyyyymm.txt</tt>. For example, a file for December 2003 is called ''ExtraLog200312.txt''.
If no logs seen, see [[FAQ#I_can.E2.80.99t_find_my_data_files.21|FAQ: I can't find my data files]]. Also note, this '''Extra data logs''' viewer is only for viewing monthly extra sensor log files (not any other files in the same ''data'' directory), the column headings for extra sensor files will always be shown at the top of the screen.
== Manipulation outside Cumulus ==
Any log files for ''previous'' months can be edited (outside Cumulus) with Cumulus running. The current month log file can also be edited outside Cumulus, but you must stop Cumulus first.
