    For a basic setup you only need to set Host, User and Password but it is recommended to change Topic to avoid issues. Each device should have a unique Topic.. Host = your MQTT broker address or IP (mDNS is not available in the official Tasmota builds, means no .local domain!); Port = your MQTT broker port (default port is set to 1883); Client = device's unique identifier. MQTT Client Id – You can use the “Generate a random ID” button (most tools will offer such a button) or provide one yourself. This ID will be linked to your device in Cumulocity IoT. To reconnect to the same device, use the same ID. Protocol – Select the protocol to be used, for example, mqtt/tcp. Host – Provide in the URL your tenant. .
