Recently there is a new version of the DSM (5.2).
If you use the Zwave/EnOcean service, you have to uninstall and install PulseStation.
Because PulseStation installs some drivers that are needed to use USB Dongle.
These drivers are not backup when there is a DSM Update.
DSM 5.2 ?
Note : You can use the backup’s service to restore your data after the reinstallation.
