Spakrplug influxdb extension not showing string values

HiveMQ Extensions
1

Hy,

I have the hivemq-ce broker with the sparkplug influxdb extension running.
If I send sparkplug b messages to the broker, all the messages with numeric data types and booleans are directly send to influxdb. The sparkplug B data that has “MetricDataType.String” is however missing in influxdb…
(I use the example.py program to send the spB messages).

Does anyone experienced the same problem and / or know a solution for this.

By subscribing to the broker, I already checked that these string messages arrived correctly at the broker.

Thanks in advance for any advice or help,
Br, Tim

Hy @Tim ,

Nice that you are interested in MQTT and SparkplugB, welcome to our community!

So, how/what are you checking in the InfluxDB that “The sparkplug B data that has “MetricDataType.String” is however missing in influxdb” ? Could you share your command(s)?

Tnx,
Dasha
