Research direction

Start by tracing how Zigbee messages from the ZTS-EUR-C device become MQTT publishes, then inspect its device definition and the handling of repeated reports. The examples show changing linkquality values while position, running, and state stay the same; confirm which reports trigger the publishes before judging a fix. Done means the device no longer floods MQTT with redundant messages while meaningful updates still arrive.
