Now that we have the using device's serial number we can start publishing messages and receiving responses containing the device's system parameter values. Lets say we want to monitor the device's '''signal strength''' and '''up time''' values. In order to do that we'll need to subscribe to the topics '''<TYPE>/<SERIAL>/signal''' and '''<TYPE>/<SERIAL>/uptime''' using the '''mosquitto_sub''' command. Again, replace the values given in the commands below with the ones in your configuration:

Lets say we want to monitor the device's '''signal strength''' and '''up time''' values. In order to do that we'll need to subscribe to the topics '''router/<SERIAL>/signal''' and '''router/<SERIAL>/uptime''' using the '''mosquitto_sub''' command. Again, replace the values given in the commands below with the ones in your configuration:

$ mosquitto_pub -h 192.168.1.1 -p 1833 -u user -P pass -t router/get -m signal
$ mosquitto_pub -h 192.168.1.1 -p 1833 -u user -P pass -t <TYPE>/get -m uptime
$ mosquitto_pub -h 192.168.1.1 -p 1833 -u user -P pass -t router/get -m uptime
In example below you can see how to subscribe and publish to the topics '''signal strength''' and '''uptime''' on RUT routers:
