Expected duration: 1 - 6 months An individual or a team may fulfil the project; however, we prefer a single point of contact to streamline our administration and ownership of this project.
This project focuses on building and testing a reliable, secure, and standards-compliant device provisioning and operations system for the Games In Real Life platform. It requires implementing a complete lifecycle of device operations—from provisioning to live gameplay interaction—using MQTT, Node-RED, Raspberry Pi, and ESP32 devices, in accordance with the operational standards and procedures (SOPs) outlined in our SOP framework.
The primary goal is to ensure that all clients can autonomously connect, authenticate, provision, synchronise, and operate within the defined environments. The contractor will deliver robust code, configuration schema handling, and documentation aligned with internal SOPs and deployment procedures.
We are seeking an experienced freelancer to assist with an IoT project utilising Raspberry Pi and ESP32 devices. The ideal candidate will have expertise in setting up Node-Red for data flow and basic GUI design, as well as management and MQTT for messaging protocols. You will be responsible for integrating sensors and devices, ensuring seamless communication between components. A solid understanding of IoT architecture and troubleshooting is essential. This project requires creativity and technical skills to optimise performance.
