sm-test-broker — the beta firmware's sandbox

This is the WebSockets face of the TEST broker. It is the same broker as the plain MQTT listener: the same accounts, the same ACL, the same test/# namespace. Nothing here can read or write a production topic.

Connect with MQTT over WebSockets at /mqtt (the mqtt subprotocol), e.g. wss://test.broker.synect.io/mqtt. Plain HTTP is refused: the edge serves this name over TLS only.

The operator's credential is a secret — ask the operator, never guess it. An anonymous client is refused by the broker itself.
