Click ‘Add’ button and then activate Rule.

Sending Temperature Telemetry

Now for any of your devices send Telemetry message that contains ‘temp’ telemetry:

{"temp":73.4}

You should receive message ‘73.4’ in appropriate RabbitMQ queue once you’ll post this message.

Here is an example of a command that publish single telemetry message to locally installed Thingsboard:

mosquitto_pub -d -h "localhost" -p 1883 -t "v1/devices/me/telemetry" -u "$ACCESS_TOKEN" -m '{"temp":73.4}'
