IoT Dashboard Developer - Real-Time Salon Chair Occupancy Display (MQTT / HTTP)

We are a premium hair salon in the UK looking for an experienced IoT / Full Stack Developer to build a real-time occupancy dashboard for our backwash (hair wash) chairs. We will be using Minew MSD01-D22 ToF Occupancy Sensors installed above each backwash chair. These sensors detect whether a chair is occupied (without cameras) and send the data via Bluetooth to a Minew Gateway. The gateway then makes the occupancy data available via HTTP or MQTT, and the hardware supplier will provide the API/documentation and technical support. We do not need any hardware development - only the software/dashboard. The system will monitor 7 backwash chairs across two floors: First Floor: 4 chairs Basement: 3 chairs We require a modern, live dashboard that can be displayed on wall-mounted screens or Android tablets throughout the salon, showing each chair as: 🟢 Available 🔴 Occupied ⚪ Offline (if applicable) The dashboard should update automatically in real time without requiring manual refresh and allow each sensor to be assigned to a chair name (e.g. BW1, BW2, etc.). Ideally, the solution will be a secure web application that can run full-screen in a browser and communicate with the gateway using MQTT or HTTP. We're looking for someone with experience in: IoT integrations MQTT and/or HTTP APIs Real-time dashboards React, Node.js or similar modern web technologies This is the first phase of a larger project, with future opportunities to add treatment room occupancy, meeting room availability and other live business dashboards.
