MQTT Jobs

I need a small hybrid mobile app built with React Native that connects to a given MQTT broker, parses the incoming JSON payload I’ll supply, and shows each message on-screen in real time. Here’s what I’m after: • A straightforward text panel—no pop-ups or interactive lists—where every new message appears immediately beneath the previous one. • Each message line should use different colours based on the message type contained in the JSON. • Display the message body together with its timestamp (taken from the payload or the broker, whichever is easier). I will share the exact JSON schema, topic(s), broker URL, and sample traffic as soon as we start. As long as the code runs on both Android and iOS simulators and is clear enough for me to tweak c...

I’m running an IoT project on ThingsBoard and now need hands-on development support from someone who already knows the Professional Edition subscription plan for Prototype version inside out. If you have previously built or customized dashboards, rule chains, widgets, or device integrations on either with or , I’d like to see a live link, screenshots, or repo that proves it. The immediate goal is to extend my current setup—adding features, refining existing dashboards, and integrating additional data sources—so please be ready to dive straight into development rather than broad consulting. Frontend; • Management for Companies – • o Company CRUD (already available just need configuration)  Configurations for the company: setup shifts (morning...

I’m building an Industrial-grade IoT proof-of-concept around a Raspberry Pi and would like an experienced mind to guide me from architecture to first live data. The goal is straightforward: use the Pi as an edge device that collects plant-floor signals, pushes them securely to the cloud, and makes the information immediately actionable for maintenance and management. Here’s where I need your help: selecting the right HATs and sensors, advising on robust enclosure and power options, tightening up my Python scripts for data acquisition, and choosing the best message broker—MQTT is my front-runner, though I’m open to your recommendations. I also want to set up a simple dashboard (Grafana or Node-RED) so operators can see real-time readings without digging through logs...

My company already has a working client-facing application with a backend that handles device control, real-time communication, and user accounts. The problem is scalability: as we release more hardware, the current architecture strains under heavy device management and the real-time layer shows cracks. Where the system falls short • Device management can’t comfortably grow with our roadmap. I need to raise overall device capacity and integrate richer performance-monitoring metrics without compromising responsiveness. • Real-time communication works, but reliability drops when traffic spikes; improving that stability is critical. What I’d like from you • Review the existing codebase and architecture (Node.js, MQTT, PostgreSQL—full repo access provided)...
