The sensor locations add a little inaccuracy to the system. The outdoor temperature sensor is not in a proper radiation proof cabinet so it heats up a little above ambient air temperature. It is also located next to the peak of the roof so if the wind blows the wrong direction, it may get some heating from the roof. The pressure and humidity sensor are part of the downstairs pressure sensor (a Bosch BME280) so they measure indoor pressure and humidity. There will be updates to this system to include solar radiation, wind, and rainfall.
