The home2net remote maintenance solution solves the typical challenges assotiated with external remote access to machinery and infrastructure. One general problem with remote access is to remember IP addresses and ports to connect to the destination equipment from remote sites. Dynamic IP addresses and changes in IT infrastructure will result in frequent problems and inability to establish connections. The home2net remote maintenance solution establishes an encrypted connection to the h2n cloud server without the need of port forwardings or static IP addresses. The home2net remote access tool is connecting to the h2n cloud with a secure SSL link and a encrypted connection will be established to the remote@ctrl device by the h2n server. The novel h2n access key infrastructure allows the owner of machines to generate time limited access tokens that expire after a specifi ed time. The typical username / password access security is replaced with time limited access keys and fully encrypted communication.
