📝 Describe your problem

I am monitoring some hardware and would like to use the MQTT monitor type.

My connected (UP) message (in JSON) is:

{"gatewayID":"[REDACTED_ID]","state":"ONLINE"}

What part of the returned response is a monitor for you?

I would expect that you would want:

{"gatewayID":"[REDACTED_ID]","state":"ONLINE"}

Tip

We use mqttSuccessMessage ⊆ receivedMessage as the comparison. See

uptime-kuma/server/monitor-types/mqtt.js

Lines 31 to 36 in 237a6e8

	if (receivedMessage != null && receivedMessage.includes(monitor.mqttSuccessMessage)) {
	heartbeat.msg = `Topic: ${monitor.mqttTopic}; Message: ${receivedMessage}`;
	heartbeat.status = UP;
	} else {
	throw Error(`Message Mismatch - Topic: ${monitor.mqttTopic}; Message: ${receivedMessage}`);
	}
