Having used Node-RED on a RaspPI to automate my brother-in-law’s cold brew coffee process (trust me it tastes great - take a look at https://www.crudedrinks.co.uk/ and buy some today!) I wondered how long it would take to create a Node-RED flow that received data from a Wirepas Mesh powered battery operated sensor node and displayed the data on my PC. This seemed like the kind of thing someone evaluating Wirepas Mesh might want to do, so how long will it take?
Most mesh networks require some form of gateway, for example to pass data from sensor devices to the cloud for capture and analysis. There are some exceptions, of course, for example smart lighting control systems sometimes do not require that data is passed to the cloud for monitoring and supervision purposes. Also there is a growing desire to do more data processing in these edge computing devices, in collaboration with cloud based systems.
We at Wirepas are focused on developing and offering the most versatile and adaptive protocol for radio communications. A protocol defines how the radio devices act in any given situation – listen before talking, only use the necessary volume etc. It is a decentralized protocol which means that every single radio does the decisions locally and autonomously, but always deterministically with the benefit of the whole network in mind. The protocol has the desired outcomes and a set of rules for the individuals which are built to yield the desired outcomes – in Wirepas Mesh these outcomes are scalability, energy efficiency, density, reliability and flexibility to name a few.
