Hi every one,

This is supposed to be very basic. I followed the tutorial on Kura publishing to the cloud on the Github.

After that I installed mosquitto-clients on my Raspi.
I try to subscribe to the service name provided in the tutorial "data" using

mosquitto_sub -h iot.eclipse.org -p 1883 -t data

but i receive nothing, in spite that the heater service is running on my PI and is publishing to the MQtt server and I am connected to the server.

Please help. I had spent a lot of time.
Thanks in advance

Ahmed

Hi Ahmed,

If you are using the Heater demo without modifications, it is publishing on a topic like <account_name>/<client_id>/heater/data. You can check the Kura log (/var/log/kura.log) to get the exact topic being used. So, you would want to subscribe to something like: <account_name>/<client_id>/heater/data. You can also use wild card characters, like: <account_name>/+/heater/#.

Thanks,
--Dave
