DHT22 Sensor

Hi, thanks for sharing the hydrosys4 project. I just downloaded the SW and connected 4 relays, the interface works fine and the relays are properly controlled by the raspberry. I also wanted to connect a DHT22 sensor (As read in the HW description I have the AM2302) but after I made the connection nothing is shown both in the Data and Setting page. Do you have any idea what could be wrong?

Thanks

Hi, if in the setting page you do not see any row relevant to sensors, in your case should be both humidity and temperature, I think this is due to the hardware setting. You can go to the HardwareSetting page, there is a drop down menu in the "select and load preset HW config" section. Choose one of the configurations and click "apply". If you only have the relay and dht22 connected, I suggest to use this: "defhwdata-Temp+Humid+8Water.txt". Let me know if it works. Thanks
