+# QNAP NAS
+
+[QNAP NAS](https://www.qnap.com/en) is a famous NAS server solution for home and business, allowing the installation of additional packages.
+
+## Prerequisite - X86_64 or ARM64 platform
+
+You need to install openHAB from [here](https://www.myqnap.org/product/openhab/). It contains the latest stable OH version and Zulu17 JDK.
+
+The easyest way is to install the [MyQNAP repo](https://www.myqnap.org/install-the-repo/) and install openHAB from there so that updates are shown when published.
+
+QNAP NAS is based on Linux but it has limitations since it is not a full server. Therefore it is recommended to use [WinSCP](https://winscp.net/eng/index.php) to access `userdata`, `addons` and `conf` folders, etc.
+
+### USB dongles
+
+USB dongles may work (or not). QTS (QNAP's operating system) may not include drivers, but you can install [USB serial drivers](https://www.myqnap.org/product/usb-serial-drivers/) (preferrably from MyQNAP repo), maybe it will include missing drivers for the dongle.
+
+### Other interesting packages in MyQNAP repo

+- Mosquitto (needs parametrization after install)
+- NodeJS v22 (required by zigbee2mqtt)
+- QGit (required to install / update zigbee2mqtt)
+- Node Red
+- FFMpeg (complement to `IP Camera` binding)
+- QPython312 (required by `HABApp`)
+- UniFi (complement to `UniFi` binding)
