Caution: MQTT Clients IDs must be unique and if two clients attempt to connect with the same client ID, one will be forcefully disconnected from the server to allow the other client to connect. |

If the server does not receive, at minimum, a PINGREQ message from a client within 1.5 times the Keep Alive, it will terminate the connection and send the client's LWT message if defined.
For MQTT Engine with Primary Host enabled, this is a message of format spBv1.0/STATE/primary_host_id with a payload {"online" : false, "timestamp" : 1668114759262}

Check your MQTT Topic subscriptions to verify if they contain valid Ignition tag path or tag name characters. View the Ignition Understand Tag Naming document for details on the tag name rules. While MQTT and Sparkplug both support characters such as . & % =, Ignition does not support these as valid characters in a tag path or tag name and as a result, it may be necessary to tell MQTT Engine to replace certain characters or strings of characters with something else so the tag path and tag names can be properly created in Ignition. Reference the MQTT Engine String Replacement HowTo for additional details on how to use this configuration. |
