Does anyone have any idea why a #DHT22 (running #ESPHome on a #ESP8266) would be giving temperatures that are 3-4 degrees higher than a thermometer that seems to be giving a more realistic reading? Thought it might be the ESP8266 heating things up but doesn't feel warm at all. Only kicking a reading out one every 60 secs. #IoT
Looks like it's a known issue with the DHT22 https://github.com/shred/dustycase/issues/1 Added a small 3V fan into my enclosure to aid airflow and it seems to be giving more realistic temperatures.
