Such projects often involve multiple parties, and their ability to collaborate efficiently is the key to the project's success. There are
- multiple parties that manage smart meters, IoT gateways and networking infrastructure that they own and
- yet another party that connects these siloed network segments together and manages them as a whole.
Managing several networks as a whole is often done using tried and tested technologies: VPNs, port forwarding, DNAT etc. These technologies are often a cornerstone to enabling efficient collaboration. If one party needs to call another one to learn why specific device is not responding, this means that the system is still operated manually and defeats the purpose of using smart devices in the first place.
