The SiteManager Software (SM-E) is available for different operating systems, such as Windows and Linux, but activates using the same license. You can preinstall the SM-E software on all your platforms, and connect to central IoT GateManager Severs FREE of charge. Once you need the SM-E for remote maintenance, the license is assigned remotely with a single click. You can then choose from two license types: BASIC, which allows cost-effective access to the platform where SM-E is installed, or EXTENDED which is a full-featured remote access gateway.
