Integration in FHEM
For the integration into the open source automation software FHEM we provide a software module for
reading in the 1-Wire Multisensor via 1-Wire Controller / 1-Wire Gateway. This means that evaluation scripts
are no longer necessary.
Details can be found on the ESERA website under "Compatible controllers - control units / FHEM integration"

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.
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".

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.

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:
