since OH 1.8 there is a binding for the LAN-based presence detection system from IPS.
In case somebody needs a solution for the USB version of the IPS-868-adapter (IPS-USB-T-868), an alternative way to connect to the AKM868 is now described in the Wiki.
@Mitch77, hope you don’t mind that I hijacked your wiki-page. I thought it is the best place to add this description.
