I like the pipes you have used to build the structure - very clever

The idea of the pipes is not mine, is from Gary, the guy who have designed the electronics of the sensors. I bought the pipes from him together with the sensors.
I could have painted the pipes with a black ink, maybe I will do it later!

Can you export to let's say Excel those data? then it would be easy to plot the differences with on bar graph?

Unfortunately I frequently delete the data from my test systems, and I don't have the full 3 weeks of data, but I have two Cumulus logs, from 00:00 July 12 to 16:00 July 17 of both systems.
One of the logs is done at 5 minutes intervals, and the other at 10 minutes intervals, but this should not be a problem.
