Questions tagged [watson-iot]

Watson IoT is IBM's platform for connecting devices, building Internet Of Things applications and making sense of the data. Communications between devices and the cloud happen via the open, lightweight MQTT protocol. With IBM's Watson IoT Platform for Bluemix, you can connect devices, gateways and applications, allowing for analytics to be performed on the real-time data collected from your organization.

The IBM Watson IoT service lets your apps communicate with and consume data collected by your connected devices, sensors, and gateways. Recipes make it easy to get devices connected to the Bluemix cloud. Your apps can then use real-time and REST APIs to communicate with your devices and consume data. For additional information on how to connect specific device types to Watson IoT Platform, see developerWorks recipes.

enter image description here

Watson IoT Platform allows you to perform device management operations, and store and access device data. You can connect a wide variety of devices and gateway devices and Watson IoT Platform provides secure communication to and from your devices by using MQTT and TLS.

Tips for asking questions about Watson-IoT:

  • Ensure you are asking a technical question about using the Watson IoT service. (For questions about your account or billing, ask at IBM developerWorks Answers or open a support ticket.)
  • Search Stack Overflow to see if somebody else has already asked the
    same question.
  • Explain what you were trying to do when you encountered the problem. What device are you using? What programing language? Was this previously working?
  • Provide the error and code samples when possible.
  • Include the watson-iot tag and ibm-bluemix tag if applicable.
  • Provide your unique 6-character org ID and any logs you have.

Getting support for Watson IoT

Stack Overflow is the best option for technical questions about programming and deploying applications using the Watson IoT service on Bluemix PaaS. The Bluemix and IoT Support teams monitor Stack Overflow closely. If you have a non-technical question, it should be posted on IBM developerWorks Answers forum or via a support ticket.
