Hello,
I have tested the DHT11 for one day with a THGR810 from Oregon (assuming it is pretty calibrated). They were close together.
There are some time the DHT11 moved but not the Oregon. Generally it was 1% below so pretty good.
On Temperature there is more gap, it varies from 2°C+/-1°C below, it is more puzzling here.
I have not yet DHT22 to do this check-up.
Would one day adjustment values sent by the gateway to the sensors ;-)
