To give a little background I'm running a RPi 3b+ and I purchased the GroveWeatherPi bundle as well as the solar add-on bundle. The RPi is totally new to me as of about 2 month ago. So to say I'm a beginner in this is an understatement. Putting the hardware together was fairly straight forward. I'm waiting on a battery and some female-female jumper cables to arrive but the rest of the setup should be wired and ready to go. So my question is where to go from here? In following the tutorial online, I have signed up for a GitHub account and followed the direction on the "README.md" file. The files seem to have downloaded and installed as best as I can tell. So the next step in the tutorial is to run the command: cd SDL_Pi_GroveWeatherPi

sudo python GroveWeatherPi.py to start the weather station. However, when i run this it says "bash: cd: SDL_Pi_GroveWeatherPi: No such file or directory etc... A few other things to note is that i have not installed the MySQL or MatPlotLib yet. I didnt know if those were for publishing online or if that is needed to simply run the system. I also have entered the RPi configuration screen and enabled I2C and rebooted. On the boards I'm getting a blue LED on the Pi2Grover as well as a blue LED on the I2C 4 Bus MU. I realize I am way over my head at this point, but I got into this hobby to learn, so I guess I have to start somewhere. So any step-by-step help you can give me on how to install/run the software would be appreciated. Thanks.

Justin,

You've made very good progress. Getting the hardware all hooked up and running.

Did you run the tests in the tutorial? i2cdetect -y 1

Now, regarding the "sudo python GroveWeatherPi.py" , your error doesn't make a lot of sense.

Run the command again and capture and post all the text involved, including your command.

Then I can see what is going on.

When I run i2cdetect -y 1 I recieve the following prompt back(The formatting is off when i copy and paste it over from the termial window but it will still show what I'm seeing).

As it sits now I currently have the OLED display, Lightning detector, HDC1080, and AM2315 hooked up. The rain/wind sensors I'm leaving unhooked for now.

When i run the start command i receive this. (Again its copy and pasted so hopefully formatting is correct)

OK.. Read the debugging and testing under the tutorial. Also run the TEST under the SDL_Pi_TCA9545 directory as in the documentation.

Have you installed the software? you should see that directory under your /home/pi directory. I don't think you have.

Looking through the tutorial online I cant seem to find where it talks about debugging and testing. I will include the commands used to install from github. All seems to go well except at the very end it asks me "Do you want to continue? Y/n" and when I type "Y" it returns "abort". Also under my home/pi directory i have a file labeled "Adafruit_Python_PureIO". I'm not sure if this the installed software or not?

Have you installed the SDL software?

Do this first:

git clone https://github.com/switchdoclabs/SDL_Pi_GroveWeatherPi

in /home/pi

Debugging:

www.switchdoc.com/2016/08/tutorial-part-7-building-a-solar-powered-raspberry-pi-weather-station-groveweatherpi/

Also run the TEST under the SDL_Pi_TCA9545 directory as in the documentation above.

Thank you for the help! I think I might be moving forward finally. After running the "sudo python GroveWeatherPi.py" command I'm getting "ImportError: No module named matplotlib". My thought was that the MySQL and Matplotlib software was for publishing data online but I take it, based on the error, that those programs are needed to read sensor data from the weatherboard?

I have also ran into a snag trying to install matplotlib. It has hung up when installing the scipy software. Your tutorial says it should take a couple hours, so I left it to run over night and all day today but is still hung up. Looking through the forums I have found another poster with the exact same problem. Your response to him was that it was "It is because the default compilation make is using all 4 cores and the Pi runs out of memory.Try using the option "-j 1""

Could you eleaborate on the -j 1? How do I use that code? Do I simply type that onto the end of the scipy installation command line? I would like to try to figure this out on my own, but in case I can't you mentioned to the other poster about having sd cards with a software image loaded up for sale. Are these still for sale?

The -j1 wouldnt work either. It would go for a couple minutes then just brick up. What did work was following the install commands at this link( raspimint.blogspot.com/2016/11/install-scipy-scikit-learn-raspberrypi.html ). So the good news is that I have finally been able to access the weatherboard! The bad news is when I tried it initially I had the lighting board(as3935) plugged in but it would immediatly come back as as3935 interrupt over and over. I unplugged the lighting board and it seemed to startup fine after unplugging it. So I'm not sure what would cause that?

Don''t need the card, willing to just pay for the download of the image.

Hi BP,

I was not commenting on the lightning detector. I have not come as far as to interpret signals. I was just replying to the possibility of preinstalled cards being available. I would not need a card, but being able to download a complete image, would make sure I get a working system. While in the meantime trying to set it up myself

The final goal is a working system.
