Yes, this makes it clear and exactly what I thought.I have add some pictures hope that makes it clear.
That's why I asked:
If you look at your first screenshot, you will see that you look at the topic:What is the topic you look at, with your MQTTAnalyzer?
plugwise2py/state/power/<MAC address of the plugwise unit>
Currently I see 9 different units.
But this topic we have decided not to use, so this is not where the MQTT input node is looking at.
The second screenshot is a copy of the first one.
But you should look at: plugwise2py/state/energy/<MAC address of the plugwise unit>
Try this one and check if you have multiple posts of the same MAC address.
