pypck is an open source library written in Python which allows the connection to the LCN (local control network) system. It uses the vendor protocol LCN-PCK. To get started an unused license of the coupling software LCN-PCHK and a hardware coupler is necessary.
pypck is used by the LCN integration of the Home Assistant project.
