import pandas as pd
import matplotlib.pyplot as plt
df = pd.read_csv("Roof_GEUS_hour.csv", parse_dates=True, index_col=0)
df = df['2022-11-09':'2022-11-11']
df[['z_boom_u','z_boom_u']].plot()
df[['wdir_l','rot']].plot()

The above code produces the following graphic

There are two SR50s here, reporting identical values.

Seems related to #3. The step change around 10 Nov is due to a station rotation (see #13).

I also swapped the two SR50 cables for this period, but you can't see that because they are not reporting unique values.

The step nov 11 at noon are also related to station rotation.
Around these dates, the stake SR50 was also relocated, now mounted together with the lab iridium antenna on the wall.

Issue #3 is a known bug, which was on the v2 stations. It has not been observed on the v3 beta/rewired untill now. The good news is that now we have a station with the problem, so we can debug it.
