FAQPage Schema
How do I design an MQTT topic hierarchy for IoT devices?▼

Design scalable and secure MQTT topic hierarchies by structuring topics with slashes to separate levels, enabling efficient broker routing and filtered subscriptions for IoT device fleets. This ensures manageable data flow across large device deployments.

What MQTT QoS level should I choose for IoT messaging?▼

Choose MQTT QoS levels based on message delivery requirements: QoS 0 for fire-and-forget telemetry, QoS 1 for acknowledged delivery, and QoS 2 for exactly-once delivery. Selecting the appropriate QoS ensures reliable communication without unnecessary broker overhead.

How does Last Will and Testament work for IoT device presence?▼

Last Will and Testament (LWT) works by configuring the broker to publish a retained message automatically when a device disconnects unexpectedly, signaling offline status. This enables robust online/offline device presence tracking across IoT systems.

Which MQTT broker should I use for IoT deployments?▼

Select MQTT brokers like Mosquitto, EMQX, HiveMQ, or VerneMQ based on your IoT deployment scale, feature requirements, and infrastructure. Broker selection guidance helps ensure reliable message routing and device management performance.

Can I use MQTT 5.0 shared subscriptions for load balancing?▼

Yes, MQTT 5.0 shared subscriptions allow multiple subscribers to share a topic load, distributing messages evenly across client groups. This feature improves performance and flexibility for high-throughput IoT messaging scenarios.
