For questions based on the publish-subscribe design pattern, especially when referring to questions about any protocol that implements this pattern. If your question is about a specific protocol (e.g. MQTT) or a specific service (e.g. PubNub), use that tag instead, and use this tag only where you need to ask generically.

Use this tag for questions that are about the publish-subscribe design pattern, especially when referring to questions about any protocol that implements this pattern. If your question is about a specific protocol (e.g. MQTT) or a specific service (e.g. PubNub), use that tag instead, and use this tag only where you need to ask generically..

Consider the question check list if your question fits the tag. You can also look at the example questions. If this tag doesn't fit your question have a look below at somehow related tags that might fit your question better.

Question checklist

  • Is the question about the publish-subscribe pattern?
  • Is the question not about a specific implementation of said pattern? (questions about programming implementations may be on-topic at Stack Overflow instead; otherwise, use a more specific tag for the implementation you're asking about)
  • Does the question describe clearly what the issue is?

Example questions

Not what you are looking for?

  • Use for questions about setting up and configuring networks for your IoT devices in general.
  • Use for questions about the operational safety of devices.
  • Use for questions about the MQTT protocol employing a publish-subscribe pattern.
