Good work! You might want to raise the wind sensor up higher to get further away from that wall and other material below it. Probably quite a bit of turbulence, vortex's, etc.
Thanks, atm its about 3meters high ontop of our chickenrun, there no walls below it, only netting and the trees behind it are a good distance away. I Found it extremely difficult finding a place to mount it cos were surrounded by dam trees, yeah it could of gone on the roof of our house, but im in a chair and my parents dont really like hights. Anyway I will see how it goes for a few days, and if Im not happy with the readings, I'll............ Well I dont know
Also the wind sensor might be tilting down slightly but Im not sure, will this effect the wind directions??
