Since a while I am trying to get the grove weather pi to work with no success. I am trying to get it all to run without the solar part, just the PI with the 5V as a power source. Should be easy I thought but apprently I am missing something. Could someone please take a look at my cabling I have done so far ... attaching 2 images. Thanks .axel Attachments:

ok thanks, I can connect 4 wires .. in the tutorial it says "JP7-1 to JP6-1". Using the best magnifier I have, I am not able to figure out which pin is what. Also the picture with the full wired up GrovePi weather is not good enough to figure out how to connect JP7 with JP6.
Anyone? Thanks!

Axel, Here is a pin # diagram of the part. This should help! BP  |

This was very helpful, thank you.
When running "sudo python GroveWeatherPi.py" I am still getting the error:

First of all, please run:
i2cdetect -y 1
and post the results.

Looks good to us!
Always tell us what you did to get it running. That really helps other people.

Great! Glad you got it working.
If you are referring to the graphs generated by GroveWeatherPi.py, then look in the SDL_Pi_GroveWeatherPi directory and look under the static directory.
pi@RPi3-60:~/SDL_Pi_GroveWeatherPi $ ls static
BarometerLightningGraph.png PowerCurrentGraph.png PowerVoltageGraph.png TemperatureHumidityGraph.png
You can link this static directory to a directory in your html directory (often under /var/www/html ) and then you can access the graphs on the web.
