You need to implement the MQTT topic subscription with the following parameters:

MQTT server name: mqtt.iotguru.live
MQTT server port: 1883
MQTT server username: mqttReader
MQTT server password: mqttReader
Subscription topic: sub/jPtvDXpb7zm375MtAKpELg/led
Subscription topic: sub/{nodeKey}/{field}

Sign in and validate your email address, and you can see the dashboard with the node key, the field and the switch buttons. Also, you can use the application to draw charts of your measurements... :)
