MQTT

Bridge MQTT messages and SMS in both directions

IoT devices communicate over MQTT. SMSEagle converts MQTT messages into SMS and back, so an alert from a sensor is sent by SMS to the right person.

MQTT: Bridge MQTT messages and SMS in both directions

SMS to MQTT and MQTT to SMS, both directions

Convert an incoming SMS into a published MQTT message, or a subscribed MQTT message into an outgoing SMS, using the same feature.

React only to what matters

Trigger a rule for every message, or only for a specific topic, sender, or message content.

Built for multi-modem setups

On multi-modem devices, choose which modem sends or receives the SMS within each rule.

MQTT: FAQ

Subscribe rules turn a matching MQTT message into an outgoing SMS; Publish rules turn a matching incoming SMS into a published MQTT message.

Yes. A Subscribe rule can trigger always, or only for a specified topic or message content.

Yes. In one Subscribe rule you can select several contacts and groups at once, and the SMS goes to all of them.

Yes, on multi-modem devices, each rule can specify which modem sends or receives.

The host address, port, login credentials (if your broker requires them), and the topic or topics you want to listen to or publish to. TLS/SSL is supported on both sides if your broker uses an encrypted connection.

MQTT is a built-in feature available on all current SMSEagle hardware SMS gateways.
