Welcome to the MQTT mailing list and discussion group.

MQTT is a lightweight publish/subscribe messaging protocol originally developed for sensor applications. MQTT is extremely useful and widely adopted in mobile environments due to the low power consumption, simplicity of API, and small bandwidth used. Clients and servers are available in various languages including C, Python, Erlang, C#, Java etc - see for more information about the protocol and the community around it.

This group is intended to bring together discussions of the protocol and different implementations. Other discussion media exist (for example, individual software implementations may have their own project resources) but this group is for discussion of the protocol and MQTT ecosystem as a whole. Off-topic debates, discussion around alternative protocols, etc. do not belong in this group. Thanks.

Initial posts will need to be moderated by a group administrator before they appear to the community.
