*FE*

# [SPECIAL PROPERTIES](#SPECIAL_PROPERTIES)

## [TH/humidity](#TH/humidity)

*read-only, floating point*  
*Humidity* read by the chip at high resolution (~13 bits). Unit is % relative humidity. Negative values indicate a condensing condition. Conversion takes about one second.

## [TH/latesthumidity](#TH/latesthumidity)

*read-only, floating point*  
Latest measured humidity. Reading this node will never trigger a combined humidity/temperature conversion. Intended for use after a previous read of the **TH/temperature** node or in conjunction with **/simultaneous/iblss.**

## [TH/temperature](#TH/temperature)

*read-only, floating point*  
*Temperature* read by the chip at high resolution (~13 bits). Units are selected from the invoking command line. See [**owfs(1)**](/man/os/owfs/owfs.1) or [**owhttpd(1)**](/man/os/owfs/owhttpd.1) for choices. Default is Celsius. Conversion takes about one second.

## [TH/latesttemp](#TH/latesttemp)

*read-only, floating point*  
Latest measured temperature. Reading this node will never trigger a combined humidity/temperature conversion. Intended for use after a previous read of the **TH/humidity** node or in conjunction with **/simultaneous/iblss.**

## [TH/led](#TH/led)

*write-only, yes-no*  
Switches the indicator LED on/off.

## [firmware](#firmware)

*read-only, ascii*  
Firmware version of the Smart Slave displayed as major.major number. Firmware versions of the SS-WALL-TH before 1.4 had known issues with humidity reporting.

## [subtype](#subtype)

*read-only, ascii*  
Subtype of the Smart Slave. Currently only possible value is "TH" signifying an SS-WALL-TH drywall temperature/humidity sensor.
