MQTT Jobs

I run a fleet of 3000-plus smart water dispensers spread across multiple client locations and need a single web application that lets me see what is happening at each device the moment it happens. The core of the build is a full-stack solution: a React / front-end talking to a Node.js or FastAPI back-end, with MQTT handling the ingestion stream. Data persistence will live in PostgreSQL with the TimescaleDB extension so we can store high-frequency time-series readings while still keeping queries snappy; Redis will sit in front for real-time queues and caching. The most critical values that must update in real time are TDS and Temperature, though the schema should already accommodate pH, turbidity and any future metrics so I can turn those on without major refactoring. Multi-tenancy is ...

I need a full-stack IoT platform built with the Django web framework tied to an EMQX MQTT broker. The core of the system is robust device management rather than analytics or dashboards. It must comfortably handle well over 200 connected devices and give me precise operational control. Key capabilities I must have • Remote configuration – After a device authenticates with the broker, I want to change its settings from the web UI or mobile application (the design is ready) endpoint. Think parameter tweaks, mode switches, or threshold values that the device can pick up over MQTT downlinks in near real-time. • Firmware updates – The platform should let me upload new firmware, roll it out to selected device groups, track upgrade progress, and provide rollback if somet...

We are looking a technically strong IoT Consultant with hands-on experience in designing and scaling IoT solutions from prototype to production. The ideal candidate should have expertise in IoT architecture, cloud integration, connectivity protocols, and device security.

Work with protocols such as MQTT, CoAP, HTTP/REST, and LoRaWAN. Build and manage IoT solutions on AWS IoT Core, Azure IoT Hub, or Google Cloud IoT. Implement device security, identity management, X.509 certificates, and secure boot processes. Troubleshoot connectivity, latency, and hardware-software integration issues. Collaborate with stakeholders to convert technic...

I need a robust ML module that monitors the incoming data patterns and identifies failure patterns in advance. The incoming data is related to power supply parmaters like voltage, current etc. The core of the job is to take my historical performance logs and a live stream of monitoring data, train an accurate model, and expose predictions through a clean, well-documented interface that my team can plug straight into our existing control software. Here is how I picture the workflow: • Data handling: build an ingestion pipeline that pulls real-time feeds (Kafka or MQTT are fine) alongside batch uploads of past performance files, then stores everything in a format that supports fast feature extraction. • Model development: use Python with TensorFlow, PyTorch, or an equivalent d...

I’m kicking off my first tech project and need a friendly expert who can both build and patiently walk me through every step. The goal is to create an e-commerce site that also showcases a simple smart-home integration—so we’ll be tackling a combination of web development and IoT in one cohesive build. Here’s what I have in mind: • Start with a clean, scalable e-commerce front end (I’m open to React, Vue, or whatever stack you feel suits a beginner eager to learn). • Connect a lightweight back end that can later expand—Node.js or Python are fine by me, as long as you explain the reasoning. • Integrate a basic smart-home feature (for example, pulling status data from a Wi-Fi–enabled sensor or toggling a smart-plug) and display it se...

I already have a custom board built around an ESP32-D, the accompanying PlatformIO project, and fully working low-level drivers for Wi-Fi, MQTT, GPIO and storage. What I still need is the high-level logic that ties everything together so the device behaves like an intelligent Wi-Fi switch. Here is what the finished sketch must do: • Subscribe to a dedicated MQTT topic and parse the JSON commands coming from my mobile app. • Execute each command immediately, switching the relay output on or off and publishing an acknowledgement with a timestamp. • Monitor the on-board push-button; every manual activation should be time-stamped, stored locally, and later pushed to the same MQTT broker so that no event is ever lost if the connection drops. • Run both daily and week...
