11134 V2.0 R1.0 Manual
Page 2 of 6
For rooms with permanently high air humidity values, such as saunas, we recommend the
1-Wire outdoor Temperature-Humidity Sensor (Art.No: 11135).
The living area Sensor is integrated into a 1-Wire Network via screwless pressure clamps or RJ45 plug
connection (CAT cable).
The living area Sensor is designed for cable entry from the rear or side. The housing cut-outs must be adapted to
the cable entry.

Software / Control
The living area sensor is read out via 1-Wire commands for DS18B20 and DS2438 devices and is supported by
many systems, such as ESERA 1-Wire Controller, ESERA 1-Wire Gateway, Loxone PLC, WAGO PLC (via
OWOS), OWFS, FHEM (Linux), IP-Symcon or microcontroller applications.

Control via 1-Wire Controller / 1-Wire Gateway
The control and data output of the 1-Wire outdoor sensor via the 1-Wire Controller / 1-Wire Gateway is very
simplified. The current sensor data is output continuously. No query of the data is necessary and available.
If you have assigned the article number (11134) of the OWD number of this sensor via ESERA Config Tool 3,
you will henceforth receive data sets adapted to the sensor. Thus, no further formulas are necessary.
7.1
Data output 1-Wire Controller / 1-Wire Gateway
The following data formats are output for the ESERA-Automation modules. If you divide the value by 100, you get
the data with two decimal places.
Data output
1_OWD1_1|2008
=> Controller No._Module No._Data set|Temperature (°C) example: 20,08 °C
1_OWD1_2|511
=> Controller No._Module No._Data set|Voltage VCC (V)
1_OWD1_3|850
=> Controller No._Module No._Data set|Air humitidy (rF) example: 85,0%
1_OWD1_4|1200
=> Controller No._Module No._Data set|Dew point (°C) example: 12,00 °C
1_OWD1_5|80000
=> Controller No._Module No._Data set|Brightness (Lux) example: 800,00 Lux
Further information on the possibilities and commands can be found in the current programming manual of the 1-
Wire Controller /1-Wire Gateway, which can be found within Config Tool 3.
