Auto-E-Connect® Support
The ESERA
Auto-E-Connect®
1-Wire Plug and Play system will be used for the
1-Wire Bus supported. This enables fully automatic configurations of 1-Wire sensors
and actuators on the 1-Wire bus. It is optimized for industrial applications and
enables significant added value beyond the sensor and chip data.
The Auto-E-Connect function automatically recognizes ESERA chips, sensors and actuators, starts suitable
libraries and outputs fully formatted data.
The Auto-E-Connect functionality will be available from mid-2020 via 1-Wire Controllers, 1-Wire Gateways and
1-Wire ECO from ESERA available.
Further information on ESERA Auto-E-Connect can be found on the ESERA website, ESERA Config-Tool 3, or in
the download area for this article in the ESERA Webshop.

Software / Control
The 1-Wire Multisensor Pro is being read out per 1-Wire commands for the DS2438 modules. The sensor is
supported by many systems such as ESERA Station, Loxone, IP-Symcon, OWFS, FHEM (Linux) or
microcontroller applications.
For ESERA 1-Wire Multisensors of the Pro series no elaborate formulas are necessary.
A sensor controller within the Multisensor takes over the preprocessing of all measured values and thereby
enormously simplifies the integration into 1-wire systems. The measured values are no longer dependent on
the operating voltage of a 1-Wire Multisensor.
The values measured by the sensor are assigned to the standard DS2438 module values as follows:
VDD = operating voltage (5V), TEMP = temperature, VAD = humidity, Xsense = no data output, fixed at 0.
