Why MQTT
Why MQTT for smart home
Connect home devices, automation services, and AI agents with lightweight MQTT messaging for responsive control and smarter automation.
Flexible home automation
Connect devices and applications through MQTT topics so automation can evolve without direct links between every system.
Continuity across reconnects
Use MQTT over QUIC with compatible clients to reconnect faster and keep device connections resilient on unstable networks.

FAQ
Frequently asked questions
A broker receives messages from devices and applications and routes them to matching subscribers. It provides a shared communication layer for device status, sensor readings, and commands.
MQTT has low messaging overhead and supports two-way communication through topics. QoS and session settings help applications handle reconnecting devices.
MQTT uses persistent connections and publish-subscribe messaging, which suits frequent updates sent to multiple recipients. HTTP uses request-response communication and remains useful for APIs, downloads, and other application tasks.
Choose a self-managed EMQX deployment or EMQX Cloud, connect a test device, and configure topics, authentication, and permissions. Check the licensing and deployment options for your project.
Use TLS to encrypt connections, authenticate each device or application, and restrict its publish and subscribe permissions to the MQTT topics it needs. Configure these controls in EMQX to help protect device data and commands.
