Hi Michael Thanks for your reply.
I did indeed read it which made me realise the issue is what WeeWx is receiving (in relation to what its displaying on the webpage) & that it needs to be calibrated somewhere. I will first calibrate the hardware & then check what value from the hardware is being displayed on the webpage. I'm pretty certain at the moment Relative Pressure from hardware = Barometer on the webpage but will double check so I know in future.
