I’m building a remote-access MQTT broker dedicated to industrial environments and I need an experienced developer to set it up, harden it, and prove it can reliably move three live data streams—temperature & humidity, machine-performance metrics, and energy-consumption readings—out of the plant and into our analytics layer. Here’s what I expect: • A production-ready MQTT server (Mosquitto, EMQX, or another broker you recommend) installed, secured with TLS and user/password or certificate-based authentication. • Topic structure and retention policies designed so JSON payloads and lightweight ASCII strings both publish and subscribe cleanly. • Sample publisher and subscriber scripts that demonstrate end-to-end delivery for each data type, plus brief documentation on how to extend them. • A quick performance test (latency, throughput) with results shared so we know the setup will handle expected message volume. • Final hand-off package: source configs, scripts, and a short read-me outlining installation, startup, and backup steps. If you have previous work with industrial telemetry or OPC UA / Modbus gateways feeding MQTT, let me know; otherwise solid MQTT experience is enough. I’m ready to start as soon as you can outline your approach and timeline.

Hi I have completed about 10 projects that included establishing MQTT data monitoring and analytics client-server modification. Multiple types of data were handled, starting from temperature and humidity (easiest part) and finishing with moving images as binary data. I have worked with industrial telemetry devices like Schneider, Siemens etc. I have also built custom solutions by myself for the automatic aquaponic farms. I can also work with JSON and lightweight ASCII payloads To find a common ground please answer the questions below: 1) How the data is collected? Do you have some middle layer except a server? 2) What are the throughput and performance results to achieve. 3) Can you describe the infrastructure for the client? I’m happy to discuss the details over chat, and I will respond promptly. Thanks for your attention Archil

Topic hierarchy is worth getting right from the start on an industrial MQTT setup. A flat structure works fine at small scale but becomes a retention and ACL nightmare fast, so I'd design around something like factory/{site}/{device_type}/{device_id}/{metric} from day one, with per-prefix retention policies rather than a global setting. For the broker I'd go Mosquitto, listener-level TLS with mutual cert auth, password fallback, and per-category ACLs. The cert chain is where these deployments get sloppy, server cert, CA bundle, and client cert validation all need to be in the right order, otherwise TLS is just cosmetic. I'd set that up properly and verify it before handoff. Sample publishers and subscribers in Python, one script set per reading type (temperature/humidity, machine metrics, energy). JSON payloads with timestamps, device IDs, and SI units. I'd include a subscriber that logs to stdout and one that writes to a flat file, so you can see both patterns. For the performance test I'd do a throughput sweep, ramp message rate up from 100/s until the broker starts queuing, record p50/p99 latency at each step, and hand you a short table with actual numbers from a real run. Deliverable in 3 days: broker with TLS and auth configured, topic structure and ACL rules documented, sample scripts for all three sensor categories, a latency/throughput table, and a setup doc covering how to add a new device type or sensor later. Is this going on existing hardware or a new VPS?

OPC UA and Modbus-to-MQTT bridges feed industrial metrics to Mosquitto in several production plants I manage. Your use case—three telemetry streams, with strict security—maps directly to how I build these: hardened Mosquitto with user/cert auth, separate topics per stream, JSON- and ASCII-friendly retention, and client scripts for test and demo. I’ll set up on your preferred OS, secure traffic with TLS, document the config, and supply both Python and Bash test clients. Latency and throughput test results come from realistic payload sizes, not just a hello-world ping. What peak message rates and payload sizes do you expect per stream? That decides tuning and limits.

I’ve built and deployed MQTT-based monitoring systems for industrial clients, including an irrigation monitor where ESP32 nodes published sensor data to a Mosquitto broker with a React dashboard consuming live streams under 200ms latency. Your project fits exactly what I do. I handle the full stack — firmware, broker setup, backend APIs, and frontend dashboards — so there’s no handoff between vendors. I’ve also implemented TLS on ESP32 for secure MQTT communication, which seems relevant given industrial data sensitivity. The budget and scope look straightforward. I’ve shipped similar systems for clients in India before, so time zones won’t be an issue. Let me know if you want to discuss the architecture or any specific requirements.

Hi, Three live data streams — temperature & humidity, machine-performance metrics, and energy-consumption readings — over MQTT is a pretty standard industrial telemetry pattern, but the hardening part is where most setups cut corners. TLS + certificate-based authentication with proper ACL topic isolation is non-negotiable in plant environments. Here's what I'd set up: - EMQX (my recommendation over Mosquitto for this scale — better dashboard, rule engine, and built-in performance metrics) - TLS with self-signed CA + per-device certificates - Topic structure with JSON payloads and ASCII strings cleanly separated by device/type - Python publisher/subscriber scripts for each data type with latency/throughput test results - Full hand-off package: configs, scripts, and a read-me covering installation, startup, and backup steps I've deployed production Linux servers on AWS/VPS with Python-based integrations and have the sysadmin depth to lock this down properly. One question: are the three data streams coming from separate PLCs or a shared gateway — and do you already have OPC UA or Modbus bridges in place, or is this raw MQTT from the devices?

Hi, I’m Armin Nikdel. I’d set this up with Mosquitto unless you need EMQX clustering now: it is lean, well-tested, and easier to harden for a single industrial telemetry broker. I can configure TLS, username/password or certificate authentication, topic naming for temperature/humidity, machine metrics, and energy readings, plus sensible retention for JSON and lightweight ASCII payloads. I’ll prepare sample publisher/subscriber scripts for all three streams, run a latency/throughput test with clear results, and add a short readme covering startup, backups, and extension points. I’ll use server-side validation where the scripts accept input, least-data logging, rate limiting where appropriate, and a backup-friendly config layout. My bid is INR 37500 with delivery in about a week. One blocker before starting: do you already have the analytics endpoint format/topic expectations, or should I define a clean topic and payload convention for the first version?

Hi, I can set this up using EMQX (preferred for industrial-scale MQTT) with TLS encryption, certificate-based auth, and hardened broker configuration for production use. I’ll design a clean topic hierarchy for your three streams (telemetry, machine metrics, and energy data) with appropriate QoS and retention rules. You’ll get working Python publisher/subscriber scripts, end-to-end testing for all streams, and a lightweight load test (latency + throughput results). I’ll also include full deployment configs, security settings, and a clear handover guide. Timeline: ~4–6 days for setup, testing, and documentation.

I can build this as a secure MQTT telemetry gateway, not just a basic broker install. Approach: 1. Confirm server target: cloud VPS or on-prem Ubuntu, expected message rate, and analytics destination. 2. Install and harden Mosquitto for a lean setup, or EMQX if you want a stronger management UI / scaling path. 3. Configure TLS, users/certificates, ACLs, topic naming, retained-message rules, and payload conventions for JSON plus lightweight ASCII strings. 4. Create sample publisher/subscriber scripts for temperature/humidity, machine performance, and energy consumption. 5. Run a small performance test and deliver latency/throughput results with the test method. 6. Hand off configs, scripts, and a README for install, startup, backup, credential rotation, and extending topics/devices. Bid: 56,250 INR / 7 days. Please fund the Freelancer milestone before production work starts. Assumptions: you provide server/VPS access, domain or IP, expected volume, sample payloads, and analytics endpoint or destination format. If OPC UA/Modbus gateway integration is needed beyond MQTT sample inputs, I would quote that as a second milestone after the broker is proven. Not included in this milestone: hardware installation, plant network rewiring, full analytics dashboard, large historical-data migration, HA cluster, or custom OPC UA/Modbus driver development unless explicitly added.

Hello, I hope you're having a great day. I've delivered several MQTT and Linux server builds for production telemetry. Recently I set up Mosquitto on Ubuntu, enforced TLS with client certificates, and bridged Modbus telemetry via Node-RED to support about 500 messages per second for machine metrics. I'd start by installing Mosquitto, applying TLS and ACLs, and defining topic and retention policies for JSON and ASCII payloads. I'll provide Python paho-mqtt publisher/subscriber scripts, a small MQTTBench test, and brief docs. No fuss. If you have ten minutes, I'd like to compare notes on expected message size and whether you prefer password or certificate-based auth for the plant gateways. Thank you, Bhargav -

Hi I can deploy a secure, production-ready MQTT broker with TLS authentication, design an optimized topic hierarchy, create publisher/subscriber scripts for all three telemetry streams, perform performance testing, and deliver complete documentation for deployment and maintenance. Questions: 1. Which cloud or server environment will the MQTT broker be hosted on (AWS, Azure, VPS, on-premise, etc.)? 2. Will the industrial devices publish directly to MQTT, or will data first pass through an OPC UA/Modbus gateway? if looking for expert then lets connect (expereince 7 yrs in development)
