1 Product description
With the ESERA 1-Wire Multisensor Pro you have acquired a professional and highly accurate Multisensor.
Due to the new technology of the ESERA 1-Wire Pro sensors, the accuracy of humidity measurements is on
average 200 –300 % higher compared to most standard sensors on the market.
Due to the use of highly integrated sensors with 12-bit resolution, the 1-Wire Multisensor delivers very
accurate values for temperature and relative humidity. In addition, the evaluation of the delivered measured
values is enormously simplified.
The 1-Wire Multisensor Pro enables easy climate monitoring of all rooms and buildings.
The 1-Wire Multisensor Pro is installed in a stylish wall-mounted housing and fits perfectly in modern living
and business areas.
Due to the wide ventilation openings, the 1-Wire Multisensor Pro detects climatic conditions in rooms and
buildings very exactly and quickly. For all types of radiator and heating control, an accurate temperature
sensor, as installed in this Multisensor, is an important component.
In combination with 1-Wire ESERA switching modules / binary outputs, a very effective and energy-saving
heating control (individual room control) is possible.
The 1-Wire Multisensor Pro is intended for use in normal living spaces. For outdoor use and in damp rooms, such
as saunas or steam baths, a matching sensor is available on the ESERA website.
Calibration of the sensors is not necessary. The 1-Wire Multisensor Pro can be put into operation immediately
without any waiting time.
The electrical connection to the 1-Wire bus system of the 1-Wire Multisensor Pro is carried out with screwless
push-in terminals and can be operated in standard mode, 3 cables for ground, data and 5V.
Each 1-Wire Multisensor Pro has an individual serial number.
2 Auto-E-Connect® Support
With the launch of the ECO Controller, the ESERA Auto-E-Connect® 1-Wire Plug
and Play system for the 1-Wire Bus is now introduced and supported.
This now enables fully automatic configurations of 1-Wire devices (sensors and
actuators) on the 1-Wire Bus. It is optimized for commercial and industrial applications and enables
significant added value beyond sensor and chip data.
The Auto-E-Connect function is built up in three levels. Currently there are
Level I, Level II and Level III available.
Please refer to the technical data to find out which Auto-E-Connect functionality is supported by this sensor.
With Auto-E-Connect Level III, fully automatic configurations of the 1-Wire devices on the
1-Wire bus are possible. It is optimized for industrial and IoT applications and enables significant added value
beyond sensor and chip data.
With the Auto-E-Connect function, ESERA devices are detected fully automatically, suitable libraries are started
and ready-formatted data is output.
The Auto-E-Connect functionality will be available for the ECO Controller and ESERA-Station 200 Pro from 2021.
Auto-E-Connect Level I
OWD Detect: Detection of new sensors and actuators and automatic start of adapted libraries.
Auto-E-Connect Level II
Visualize product data: Readout and visualization of Auto-E-Connect and manufacturer data of sensors
and actuators, such as article number, date of manufacture, firmware and hardware version.
Auto-E-Connect Level III

oAutomatic Positioning: The device logs on to any ECO Controller with Auto-E-Connect III with the new
request OWD number. This automatic login works up to the maximum possible OWD number of the
ECO controller
oSensorfinder Function: The ECO Controller can activate a status LED within the ESERA 1-Wire Pro
sensors. The status LED flashes or lights up permanently for a certain time. This makes the detection of
a device in a 1-Wire network much easier. A faster detection saves a lot of time and therefore money
when searching for a 1-Wire device.
oClasses Assignment: ESERA 1-Wire devices are assigned to OWD classes with the same properties.
This assignment enables fully automatic visualization and data evaluation in control systems. A class list
is available from ESERA.

6 Software / Control
The 1-Wire Multisensor Pro is read out via 1-Wire command for DS2438 modules. The sensor is supported by
many controllers like ESERA-Station, Loxone, IP-Symcon, OWFS, FHEM, (Linux) or Micro Controller
applications.
For ESERA 1-Wire Multisensors of the Pro series no complex formulas are necessary anymore.
A sensor controller within the Multisensor takes over the preprocessing of all measured values and thus simplifies
the integration into 1-Wire systems enormously. Also, the measured values are no longer dependent on the
operating voltage of the 1-Wire Multisensor.
The sensor measured values are assigned to the standard DS2438 device values as follows:
VDD = operating voltage (5V), VAD = humidity, Xsense = no data output, fixed at 0
Calculations
Temperature
Standard output according to DS2438 module
Operating voltage
Standard output according to DS2438 module
Humidity
To obtain the rel. humidity in percent, multiply the output value (Vas) by a factor of 10. 0.1V corresponds to
1% relative humidity.
7 Data output 1-Wire Controller / 1-Wire Gateway
For the 1-Wire Multisensor Pro, the following measured values are calculated and output by the 1-Wire
Controller / 1-Wire Gateway. The dew-point calculation is a function of the 1-Wire Controller /
1-Wire Gateway.
Data output:
1_EVT|12:27:40
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|470 => controller no._module no._data set|humidity (rF) example 47,0%
1_OWD1_4|1200 => controller no._module no._data set|dew point (°C) example: 12,00 °C
Further information for options and commands can be found in the latest available documentation for
1–Wire Controller / 1–Wire Gateway.

https://www.esera.de/kompatible-steuerungen-zentralen/fhem-integration/
11 Measurement accuracy
The sensor elements inside the 1-Wire Multisensor Pro are calibrated. Please note that the measuring
accuracy may possibly decrease towards the measuring range limits as well as at very high/low operating
temperatures.
12 Connection
The 1-Wire Multisensor Pro is connected by screw terminals.
The connection terminal is intended for solid cables with 0.2 to
2.5qmm or fine wire cables with 0.2 to 1.5qmm cross-section.
For the connection we recommend slotted screwdriver size
2,5x75.
The pin assignment is printed on the circuit board.
The correct polarity must be observed during connection.
The Multi-sensor must be connected with three cables (ground,
1-Wire Data and 5V). Parasitic mode is not supported.
13 Assembly
The mounting location must be protected from direct sunlight, moisture (e.g. dripping water) and drafts. The
device may only be used in dry indoor rooms and in protected outdoor areas. During installation, make sure
that the ventilation openings are located at the top and bottom. Also note the imprint of the direction of the air
flow on the connection side of the unit
A draught-free location must be selected for installation. The unit is intended for installation inside a living
room as a stationary unit. The 1-Wire Multisensor can be ideally mounted on a flush-mounted box through
clever housing cut-outs.
14 1-Wire Network Cabling
The special feature of the 1-Wire system is the "BUS technology". All devices (sensors and actuators) are
operated in parallel on a three-wire line, which is used for both power supply and data communication. The 1-
Wire bus system joins the list of other successful bus systems such as CAN or Modbus RTU. All of the installation
principles recommended for these are also applicable and appropriate to 1-Wire.
The maximum size of a 1-Wire Network is determined by various factors. These are mainly:
Note
The module may only be operated at the voltages and under the ambient conditions intended for it. The
operating position of the device is arbitrary.
The modules may only be commissioned by a qualified electrician.
For further information on the operating conditions, see the following instructions under
"Operating conditions".

- Total cable length and cable type
- Number of 1-Wire devices
- Type of cable installation (topology)
- Number and design of cable connectors (unnecessary connection transitions should be avoided)
All factors in total are summarised and referred to as 1-Wire Bus load. Each increase of a factor increases the
total 1-Wire Bus load for the 1-Wire controller and thus reduces the maximum network size.
According to our many years of experience and a lot of feedback from customers, the following conservative
recommendation can be made:
- Maximum cable length 50 -120m
- Number of 1-Wire devices no more than 20 -22 pieces
- As linear a topology as possible without T-junctions
The topology in particular plays a major role. If possible, linear topology should be used. The linear topology can
be compared like pearls on a pearl necklace. The data line should be laid from one device to the next without
T-joints.
Furthermore, the type of cable used can also be mentioned here. We recommend for the cabling
CAT5 or CAT6 network cable. It is also possible to use J-Y(St)Y telephone cables and KNX cables. Longer cable
runs are possible with CAT5 versus CAT7 cables.
With twisted pair cables, a longer connection length can be achieved in an undisturbed environment, as the
capacitive bus load is lower. A total length of 50 m and more can be easily achieved without additional measures.
In disturbed, commercial and industrial environments, the cable should always be shielded in order to increase
the "robustness" or interference sensitivity of the system
15 Operating conditions
The Multisensor is designed for temperature and humidity measurements of air and gases indoors, such as
living spaces, offices, workshops or public facilities. The measured values given under technical data are
limit data for the entire 1-Wire Multisensor and must not be undershot or exceeded, otherwise the sensor
may be damaged.
