Nowadays, IoT and smart Grids are trending topics in research and technology applications: In fact the market for both services and products were in the hundred billions of dollars yearly in 2016. This work describes how the LoRa and G3-PLC technologies are brought together to create a hybrid sensor network testbed to deliver IoT applications in a campus of ten buildings, through an application oriented approach. The idea derives from the pursuit of creating added value in a privately owned campus, where an internal sensor network can be an opportunistic tool for the improvement of energy management, control and energy consumption metering, thus offering a better service to customers. The reader will be guided through the process steps that the team took in order to obtain the results here presented: First the architectural structure of the network will be explained, then its implementation will be described. A campaign of measurements is presented, which was carried out to test the fitness of LoRa as an outdoor connectivity technology, of PLC as an indoor solution and globally assessing the performance of our network.
