MQTT integration & automation experts
We can help you automate your business with MQTT and hundreds of other systems to improve efficiency and productivity.
What you can automate with MQTT
MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for devices with limited processing power and networks with constrained bandwidth. It uses a publish-subscribe model: devices publish messages to a topic on a central broker, and any client subscribed to that topic receives the message. MQTT runs over TCP/IP and is the dominant protocol for IoT (Internet of Things) communication, used in everything from factory sensor networks to smart building systems. The n8n MQTT node allows workflows to subscribe to MQTT topics and trigger automations when messages arrive, or publish messages to topics as part of a workflow. This makes it possible to connect IoT device data to business systems — for example, reading temperature sensor data from a warehouse and triggering an alert in Slack, or receiving machine status updates from factory equipment and logging them to a database for reporting. At Osher, we use the MQTT node in n8n to bridge the gap between operational technology (sensors, PLCs, edge devices) and business systems (databases, dashboards, notification channels). If your business collects data from physical devices and you are manually exporting or checking it, our system integration services can connect those data streams directly into your workflows so the information reaches the right people and systems in real time.

Common questions about how MQTT consultants can help with integration and implementation
How it works
We work hand-in-hand with you to implement MQTT
As MQTT consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate MQTT with integrate and automate 800+ tools.
Step 1
Assess Your IoT Infrastructure and Data Flows
We review your existing IoT devices, MQTT broker setup, topic structure, and message payloads. We document what data is being published, how often, in what format, and where it currently ends up. This tells us exactly what n8n needs to subscribe to and what transformations are required.
Step 2
Define the Business Automations
Working with your team, we identify what should happen when specific MQTT messages arrive — alerts, database writes, dashboard updates, work order creation, or escalation procedures. We map each MQTT topic to a specific business action and define the rules (thresholds, filters, time windows) that govern when each action fires.
Step 3
Configure MQTT Connectivity in n8n
We set up the MQTT credentials in n8n, configure TLS, select the right QoS levels for each topic, and test the connection against your broker. We verify that n8n receives messages reliably and that the payload parsing works correctly with your specific message formats.
Step 4
Build the Processing Workflows
For each business automation, we build an n8n workflow that subscribes to the relevant MQTT topic, parses and transforms the incoming data, applies business logic (threshold checks, deduplication, aggregation), and sends the result to the target system — whether that is a database, a notification channel, or another API.
Step 5
Implement Monitoring and Error Handling
We add health checks that alert you if the MQTT connection drops, if message volume falls outside normal ranges, or if a workflow fails to process a message. Dead-letter queues capture any messages that could not be processed so nothing is silently lost.
Step 6
Deploy and Validate in Production
We deploy the workflows to your production n8n instance, monitor the first few days of real MQTT traffic to confirm everything processes correctly, and hand over documentation covering the topic subscriptions, workflow logic, and troubleshooting procedures.
