Domoticz

I use wemos D1 mini with her dht22 shield, everything work as expected, but position shield just above the ESP give me 3 degre offset, so I want use the adjustment for operate correction, unfortunately when I apply this adjustment nothing happen!

You don't say which ESP8266 firmware you are using on your Wemos D1 Mini.

Assuming you are using the ESPeasy firmware, then under Devices / DHT22 edit - in the formula box enter:
if 3 degrees too high then: if 3 degrees too low then: I have just got 4 DHT22 sensors, I have attached them to one Wemos D1 Mini and I am sending all 4 values back to Domoticz, just playing with offsets to understand how accurate / reproducible the measurements are.

ESPeasy is well documented here: http://www.esp8266.nu/index.php/HumiditySensor

many tanks simonrg, exactly what I looking for you are right ESP Easy R78
My offset : -3.5 for temperature and + 5 for humidity, did you have something similar?
