Look in SGS.py at about line 88 and make sure that you see this.
#############
# Debug True or False
############
DEBUG = True
Re-run your program and post the results.
Also, are you running Blynk? If you are, show us the plant moisture screen.
I'm wondering if your moisture sensors are reading 0 and so the software thinks it is a fault.

Thank you for the information.
Looks like the system is working but the pump is not turning on.
Would you plug the USB Pump directly into a USB port and see if it is pumping?
Also, you should see a blue light on the USB PowerControl NE board when the pump is activated. Are you seeing that?

This is how the Smart Garden System is preforming now: The Blynk app is able to turn the pump ON for just about a second when the MOISTURE SENSOR reading is above 60. Blynk does the same (ON for 1 second) when the MOISTURE SENSOR is out of the soil and the moisture reading is 6. I would expect it to stay ON until it received a MOISTURE SENSOR reading >= the threshold setting of 60. Here is a video of the OLED with the Moisture Sensor reading 6. Pump and USB PowerControl NE board are good. Its interesting how the OLED scroll sequence pattern of: #OMS FLT!, ALARM!, #OMS FLT!, PLANT DRY, ALARM! does not repeat the same.
Sorry about the video audio — doing the morning dishes while recording. Thanks for your continued help. |

OK. Now I get what you are worried about. The pump only turns on for a few seconds every 15 minutes until the threshold reaches 60%. It looks like the system is thinking there is a fault on the moisture detector. Alarm_Moisture_Sensor_Fault = 15.0 is in state.py
If the system thinks the moisture sensor is faulted, it overrides the water command and does not water. That covers a number of sins.

Great, thanks for explaining the logic. Took awhile to sink in. Makes sense to turn the pump ON and water a short amount of time (line 219 of SGS.py) wait 15 minutes (line 88 of state.py) — check Moisture sensor and run the pump again if <60. Smart approach to keep from over flooding the surface of the plant while it takes time for the water to soak down into the soil for a proper Capacitive Moisture sensor reading.

Hi, I have exactly the same problem. I purchased the SD card and followed the instructions. The water calibration worked fine. I also have an alarm PLANT DRY (I purposely bought a poor, neglected, dried up plant that I thought would be good for SGS to nurse back to health). It seems there are a few instances of this problem, so is there a direct way to turn on the board that controls the pump? I didn't test the pump directly yet by connecting it to 5v, but someone else above did and it worked fine. Just waiting for ideas ...
Also, I read the bit above re short turn on time, but the tube seems to be dry, as if no water has been pumped. I will watch it for a while, but can I expect to hear it when it pumps??
Just tested the pump directly with 5v - works fine!
Regards, AB |

Hi, so here I am about 12 hours later and I have determined that it is actually working. I was expecting the pump to start running continuously until my dry plant was saturated, but now I understand that it does this very slowly, turning on briefly every 15 minutes (which is a good approach). There are a few reasons why I thought it wasn't working: -I didn't understand the issue of it responding slowly, with a brief ON time every 15 minutes -The pump is very quiet and there is enough ambient noise here that I could not hear it turn on -When I ran the SGS.py initially, I got this error in the terminal screen, which made me think there was something wrong: [Errno 121] Remote I/O error [Errno 121] Remote I/O error Error accessing 0x49: Check your I2C address Error accessing 0x49: Check your I2C address Error accessing 0x4A: Check your I2C address Error accessing 0x4A: Check your I2C address Is there any way to suppress this confusing message? Also, is there any discussion somewhere about the scalability of this system? We are planning to run a fairly large greenhouse system and this is one of the solutions we are testing for that application.
One other problem I had was that I could not seem to run the testAll.py program, it was not found. Can you please tell me which folder it is in? I did find the testAllSensors.py, so I was at least able to run that.
Tks, AB |

removing the errors is a reasonable request. If we can't do that (they may be buried in libraries we have no access to) then we will document what they mean (It's part of the device detection sequence).
You can go up to 9 plants at the moment. And actually, that is 9 sensors and and 9 USB controlled devices (could be 5V Valves, etc.). With a little more hardware (an I2C Mux), you can go to 8x4+1 = 33 USB devices. That is the practical limit, although you could go higher I believe with some more thought.
Our problem. The correct program name is: testAllSensors.py
You can turn any pump on for a few seconds by using the Blynk App.

Hi, ok, good to know on the scalability issue. So with a MUX board we can have 33 USB pumps and 33 soil moisture sensors. And a typical ordinary WiFi router can support approximately 250 Raspberry Pi boards? So about 8,250 separate 'zones', each with its own soil moisture sensor and nutrient pump, per router?
Tks, AB

Yes, that is correct. I had not done the multi PI calculation!!!

and then we can also have multiple routers ...  |

Hi there I'm having the same issue as scottaandy, same i2cdetect posting as well. The pumps are posted as turning on/off both in command line and blynk but it won't actually turn on.

Post your "sudo i2cdetect -y 1" result and let's go from there.
