I started upp by connecting a ESP01 to a HDT22. Programming in LUA and using NodeMCU firmware and applying javieryanez/nodemcu-module on GITHUB. EasyPeasy it seemed to work but the I could only get a reading when I "rebooted" the HDT22 after the start. Immediately i suspected something with the power supply which was the YuRobot 3.3 and 5V breadboard supply. Then I went over to try the NodeMCU dev kit with USB support. The same configuration with the HDT22 and I got it to work perfect. But when I disconnected the the make from the computer giving it only USB power from a adapter (1A max) the temp reading gets screwed up. I have tested different adapters, decoupling capacitors, pull up resistors but still SSDD.

The setup connects with EasyIoT Cloud Beta but the temp reading gets wrong. I have a problem adding it all up..

Thanks in advance

I spent a lot of time with e-12 and dht-22 without success, using different modules from github. Finally realized, that there is a fw support in nodemcu fw for dht22. Using this, solved all my issues, and it works fine.....
give it a try!
