1 Introduction
Before you start mounting the 1-Wire Solar Multisensor and putting the device into operation, please read these
mounting and operating instructions carefully until the end, especially the section on safety instructions.
2 Product description
The 1-Wire Solar Multisensor is a combination sensor for solar-radiation, brightness and perceived temperature
that combines the advantages of semiconductor and photovoltaic sensors in one device.
The brightness sensor measures brightness values in the range of 10 - approx. 7000 lux, the PV sensor covers the
range up to approx. 1200W/m² and the temperature sensor outputs the felt temperature in the sun.
Since the solar sensor is a power sensor, the output is in watts per square meter (W/m²). The solar and brightness
sensors with their supplementary properties cover the entire range of applications for recording solar-radiation and
day/night detection and are therefore ideally suited for central light-, shutter- and shade control.
The 1-Wire Solar Multisensor is designed for permanent outdoor operation. The entire sensor is designed for a
temperature range of -40 to +85°C.
To ensure maximum reliability, the 1-Wire Solar Multisensor has an integrated monitoring of the supply voltage.
The sturdy plastic housing is designed for IP54 operating conditions. The cable entry is made by screw strangling
nipples. For wall mounting, a special mounting bracket is available for purchase as an accessory at our shop.
2.1 Photovoltaic sensor (solar sensor)
The photovoltaic sensor is designed to measure the solar-radiation in W/m². This makes the solar Multisensor very
suitable for controlling shading- or awning systems. The solar sensor covers an enormously large dynamic range
up to approx. 1200 W/m², which corresponds to approx. 1,000 up to 70,000 lux.
The sensor can be used well for estimating the expected performance of PV systems and finding a location.
Existing PV systems can be monitored by comparison measurements. Due to its design, the output voltage of the
sensor does not run with a linear characteristic curve and is subject to a certain temperature influence.
The measured solar-radiation power of the solar cell is output in watts per square meter (W/m²) by formula,
(evaluation script) and a variable for controlling a shading system is output.
The solar sensor is typically mounted on a mounting bracket (Art. No. 20003) at an inclination of approx. 45° with
orientation to the south. This allows a comparative measurement for PV systems. Rain and snow will also slide
faster from the top of the sensor.

2.2 Brightness sensor
The brightness sensor is used for the measurement of low light values and for sunrise and sunset detection. For
example, blinds can be opened or closed in the morning and evening.
A special photodiode, with a human-like detection light spectrum, converts the ambient brightness to an analog
voltage value.
The evaluation script converts the output voltage value to the current brightness value in lux and outputs a variable
for day / night control, e.g. for roller shutter control.
2.3 Temperature sensor
The solar Multisensor contains a temperature sensor that measures the temperature felt in the sun. Depending on
the weather conditions, the temperature values can deviate greatly from those measured near the ground. By
mounting the temperature sensor inside the housing, short-term falsifications of measured values due to draughts
or gusts of wind are greatly reduced.
With the temperature sensor, comparative temperature values for mounted PV modules can be easily recorded and
used to calculate the possible power reduction and plausibility check.
Depending on the installation location, the sensor can also be used as an outdoor temperature sensor. For the
exact recording of the normal outdoor temperature we recommend our 1-Wire temperature sensor waterproof, Art.
No. 11111 or the 1-Wire Multisensor Temperature, Humidity and Brightness, Art. No. 11135.

6 Software
The solar multisensor is read by 1-Wire commands for DS2438 device and supported by many software programs
and devices, such as Loxone SPS, WAGO SPS (via OWOS), OWFS, FHEM (Linux), IP-Symcon or microcontroller
applications.
Assignment of DS2438 inputs: VDD = operating voltage (Volt), VAD = brightness (Volt), XSENS = irradiation (Volt).
Evaluation brightness sensor:
Brightness (Lux) = (VDD-VAD) * 700, example: (5V-1.25 V) * 700 = 2625 lux
Note: it should be noted that the sensor has a negative evaluation, which means approx. 5V equals darkness and
approx. 0V equals full lighting.

7 Control via 1-Wire Controller / 1-Wire Gateway
The 1-Wire interface of the 1-Wire PV solar-, brightness- and temperature sensor is controlled by standard
commands for the DS2438 module. The 1-Wire Controller / 1-Wire Gateway has already stored a suitable formula
for converting the raw data of the 1-Wire module. All you have to do is assign the article number 11112 to the
corresponding OWD number using the Config Tool.

8 Integration in IP-Symcon / ESERA-Station
At our website we provide ESERA IP-Symcon software modules for reading the 1-Wire Multisensor into IP-
Symcon via 1-Wire Controller / 1-Wire Gateway. No scripts are necessary. Details can be found on the
ESERA website under "Compatible control systems/central control systems/IP-Symcon integration".
https://www.esera.de/kompatible-steuerungen-zentralen/ip-symcon-integration/
For the conventional connection via 1-Wire Bus Coupler, the sensor values must be calculated according to
the specified formulas.
9 Integration in Loxone
Via the shop we provide an example project for reading the 1-Wire Multisensor via 1-Wire Controller 1/1-Wire
Gateway. Details see here: https://www.esera.de/kompatible-steuerungen-zentralen/loxone-integration/demo-1-
wire-controller-1-loxone-integration/
10 Integration in FHEM
For the integration into the open source automation software FHEM we provide a software module for reading the
1-Wire Multisensor via 1-Wire Controller / 1-Wire Gateway. This eliminates the need for evaluation scripts.
Details can be found on the ESERA website under "Compatible Controls - Central Units / FHEM
Integration".https://www.esera.de/kompatible-steuerungen-zentralen/fhem-integration/
11 Assembly and application instructions
The sensor should be attached to a vertical or inclined surface, e.g. with the mounting bracket (Art. No. 20003) at
an angle of 45°. The inlet for the supply cable should point downwards. This is to avoid back pressure caused by
rain or snow on the cable gland.
As connection cable we recommend our PUR sensor cable (Art. No. 11114).
The maximum cable length is 100 m. The device is intended for installation as a stationary device.
If the 1-Wire PV solar, brightness and temperature sensor is operated on a 1-Wire network, we recommend
termination of the cable end with the 1-Wire Term 1 (Art. No. 11355).

12 Connection plan
The 1-Wire solar sensor is connected via Push In terminals. The connection terminal is intended for solid wires
or finely stranded cables of 0.2 to 1.5qmm cross-
section.
The pin assignment is printed on the printed
circuit board.
The correct polarity of the connection must be
observed.
The Multisensor is equipped with three cables
(ground, 1-Wire Data and 5V).
Parasitic mode is not supported.
Note: Basics and tips for the 1-Wire bus system
can be found on the ESERA website at
https://www.esera.de/1-wire-grundlagen/
13 Assembly
If the sensor is used to control shades or roller shutters, the sensor should be oriented to the south. If room lighting
is to be controlled, orientation to the north is preferable. Ensure that the sensor is not shaded by trees or chimneys.
14 Operating conditions
The module may only be operated at the specified voltages and ambient conditions. The device can be
operated in any position. The sensor is designed for continuous operation outdoors or in rooms with high
humidity.
If condensation forms inside the sensor, an acclimatization time of at least 2 hours must be waited for.
Do not operate the module in an environment in which flammable gases, vapors or dusts are present or may be
present.
15 Disposal note
Do not dispose of the device within the household waste!
According to the directive concerning old electrical and electronic appliances,
electronic devices must be disposed of via the collecting points for old electronic
appliances!
