Could anyone be so kind to tell me if the direction my Anemometer is
correct or not ? I mean judging by the direction of most of the wind
gusts today it looks more like SE / E but is this correct or not.

I guess the Anemometer should point south is this correct ?

Several points here Adrian. Looking at your wind direction graph for today
the direction has been between NE and SE. The anemometer may have been
wrongly set up in the first place. First of all you need to check using a
compass so that directions are known, a long stick to keep the wind vane
steady and then see how this known direction relates to what is shown on the
display. You may/may not then have to re-set the wind vane either at the
business end or by rotating the pole. All this assumes that the wind vane
is in a safe and accessible location. What you will probably find is that
the wind vane is set properly but you are experiencing the effect of urban
topography causing a channelling effect on the local wind direction. I
noticed this with my setup some time ago but despite checking all the
settings and an even higher pole I still get directions which are a little
too clockwise.
BTW you will probably need an assistant at the console end to help you with
checking/resetting, a mobile phone at each end and just make sure you don't
fall off the roof.

All the best
