I;ve tried 3 different BME280 modules now in case I have a faulty one and all of them give the same results
The readings are higher than the actual temperature, by around 2-3°C
I have tested it with my Weatherflow Sensor beside the BME280, a glass thermometer sat in the same place and a BME280 on a Pi Zero using Python and they all give around the same temperatures around 2-3°C lower than the MM

The MM is on  Pi Zero W using Matherps latest Picromite and the BME280 code thats on the forum

Anyone else found this or have any idea why?

I've mounted the BME280 sensor physically away from the Pi so it can't be heat from the PI affecting it.
