MQTT Logger Configuration (Target):
Lambrecht data logger support MQTT with realtime values (interval: 1, 2, 5, 10, 15, 20, 30 60 second)
depending on the quality of data transmission (Ethernet connections support the shorter intervals).
Realtime values are using its own topic on the Broker. They are transmitted with quality of service 0.
Average and extreme values are transmitted to the broker in intervals of 1, 2, 3, 5, 6, 10, 15, 20, 30 and
60 minutes. These intervals are the same time steps as used to calculate average values. A transmis-
sion interval longer than the average values calculation interval may be used. A shorter transmission
interval must not be used. Average and extreme values support quality of service 1. They use an own
topic on the Broker.
TLS encryption can be used to support a more secure MQTT transmission. It produces a significant
higher load at the processor of the data logger and a much higher data transmission volume.
The MQTT Device ID is created automatically based on the MAC address of the data logger.
