Samples WAC Binding - vpjuslin/openhab GitHub Wiki

Our WAC systems use default modbus data provided by Arduino barebones e.g. a Debian Rasberry server kit all year long. Binding is compatible with latest models since 2013' See Examples of typical WAC Bindings, if you have any suggestions or questions don't hesitate to contact us or use our Github account. The snapshot version of our industry4.0 binding can be downloaded, together with the rest of openhab.
