MQTT duplicating data, eventually failing

Hi

I managed to set-up the MQTT connector with our Siemens WinCC SCADA system.

The data however keeps duplicating each run until it eventually stops transfering. On the Siemens side eventually it start getting errors and the transfer stops.

In the image below you can see and example. The data being uploaded is only 3 individual tags updating every 10min.

The first couple of runs it seems to work as intended but then the data start duplicating without a pattern I can see, the number of rows each run tend to grow but sometimes it goes down. I then end up with some 57000 rows when there are only some 600 rows when taking out duplicates.

Eventually I need to restart the MQTT system and the cycles starts again.

I am not familiar with MQTT so I can tell if there is an issue with the DOMO Broker or what. would have expected each run to have 3 to 6 rows depending on when the the timing.

Any suggestions as to what it could be happening and how to fix it?

I tried set-up up a whole new connector but the same thing happens again
