Access to Heating System Bus with eBus Gateways and eBus Couplers: Read and Write

eBus coupler EtherneteBus to LAN data interface for PC, Raspberry Pi and Co Application With the eBus coupler you can access the eBUS e.g. of your heating system in read and write mode. With appropriate software, you can evaluate data from your heating system and send new values to your heating control system via the eBUS. Features With the eBus coupler you can access the eBUS e.g. of your heating system in read and write mode. With appropriate software, you can evaluate data from your heating system and send new values to your heating control system via the eBUS. The eBus coupler is equipped with a galvanic isolation between eBus and PC interface. The eBus input is bipolar, so you do not need to pay attention to the polarity of the eBus when connecting. The housing of the eBus coupler is designed for control cabinet installation. As data interface to your PC, the eBus coupler is equipped with an Ethernet interface. Drivers for Windows operating systems are available.The eBus coupler is not supported by Vaillant vrDIALOG software. A very good example (VWMon by Alexey Ozerov) for reading out eBus data can be found here or the project Fhem here

eBus coupler USB: eBus to USB data interface for PC, Raspberry Pi and Co.Application With the eBus coupler you have read and write access to the eBUS e.g. of your heating.With appropriate software you can evaluate data of your heating and send new values via eBUS to your heating control. FeaturesThe ESERA eBus coupler is equipped with a galvanic isolation between eBus and PC interface.The eBus input is bipolar, so you do not need to pay attention to the polarity of the eBus when connecting.The housing of the eBus coupler is designed for control cabinet installation.As data interface to your PC, the eBUS coupler is equipped with a USB interface of the manufacturer FTDI. Drivers for Windows, Linux and further operating systems are available via the FTDI page.Note: The eBus coupler is not supported by Vaillant vrDIALOG software. A very good example (VWMon by Alexey Ozerov) for reading eBus data can be found among others here or the project Fhem here Note: We recommend to use a USB hub with power supply. This ensures a continuous power supply independent of e.g. a Raspberry Pi.

 eBus to seriell coupler The eBus Coupler Serial provides read and write access to the eBus network. Thus with appropriate software it is possible to analyze all of your home heating system data and provide it with new operating data.The E-Service eBus Coupler Serial provides galvanic isolation between the eBus and the PC serial interface. The built-in software filter ensures that only payload data is transmitted over the serial interface. This filter significantly reduces the amount of data being transferred.The eBus interface is reverse polarity protected. Therefore it is not necessary to observe signal polarity when connecting to the eBus. The Coupler’s enclosure is designed for mounting within a control cabinet.The eBus coupler is equipped with an RS232 serial interface for transferring data to and from the PC. On the Coupler’s front panel there are LED indicators for “PWR” (eBus input power) and “DATA” (eBus activity). In the area of the eBus terminals there is additional a green LED which indicates the presence of an eBus. An external power adapter which is not included as part of the eBus Coupler delivery is required to operate the eBus Coupler. A very good example from VWMon of Alexey Ozerov for reading data eBus see you can found here or the project FHEM here

The ECO 305 ETH provides a convenient and efficient way to control and monitor your heating system over the network by establishing a connection between eBus protocol and Raspberry Pi and ebusd* software.APPLICATION Heating cost and energy optimization for all building heating systems with eBus interface*.The ECO 305 ETH eBUS gateway offers the possibility of a heating cost and energetic optimization for all building heatings with eBus interface. For all heating systems, gas, oil, solar and heat pumps. The ECO 305 ETH eBUS Gateway offers heating cost and energetic optimization for different types of heating systems, including gas, oil, solar and heat pump systems. Manufacturer-independent the ECO 305 ETH eBUS Gateway works independently of any manufacturer. It is compatible with various heating systems from different manufacturers as long as they have an eBus interface.ADVANTAGE Heating cost savings of up to 25 % The ECO 305 ETH eBUS Gateway together with the ebusd software can lead to heating cost savings of up to 25 %. These energy savings may vary depending on the specifics of your building and heating system Increasing home comfort.The ECO 305 ETH eBUS Gateway helps increase home comfort The ECO 305 eBus Gateway is a powerful, latest-generation interface that acts as a link between your heating system and the ebusd* software. It allows you to access your heating system in read and write mode, independent of the manufacturer, and to perform optimizations. The eBus Gateway has been optimized especially for the communication with the software "ebusd "* and supports the extended command set (Enhanced Mode) of ebusd*. In addition to the eBus functions, the eBus gateway has an access point and a web server to enable easy operation and configuration. Via the LAN interface you can communicate with up to 2 data connections using the ASCII text protocol. The ECO 305 is a new eBus coupler with a standard 2400 baud data interface and an "Enhanced Mode" extension. It does not perform any data analysis or evaluation itself.The fully automatic level adjustment takes place in a few seconds on your eBus, so that a cumbersome manual adjustment is no longer necessary.You can conveniently change device settings, perform software updates and view device data via the web server. The web server can be accessed via the LAN and via the access point (activated at the push of a button). The ECO 305 eBus Gateway is a low-maintenance industrial device because it does not use Linux. It has been programmed natively and no unknown libraries are used. There is extensive software support available via ebusd** on the web. *depending on software and control and programming **ebusd is not a software of ESERA GmbH. We do not assume any liability, function promise or support for this software. The ebusd project can be found here (we do not give support for this software) ebsudFor data evaluation, customers use the following projects, among others: Note: We do not provide support for subsequent ebus projects.
