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,
Sorry for the late reply. I tested all sensors are working properly, thanks for the quick fix!
Keep up the good work!
Hi,
I built the irrigation system with your software, works like a charm. Congratulation! I have the sensors, all on the I2C are working, but only the DHT22 doesn't. I tried the sensor itself on Arduino, it's OK. I hooked up the Pi to a monitor and when checking the temp or humidity reading it gives error message, like failed to read the sensor. I didn't save exactly the error.
Do you have any suggestion, what to check?
I would like also to donate you a small amount for your work put into this software and sharing it.
Thanks!
It works! 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
