I am trying set up the weather station and this is what I get from the test run:

# python GroveWeatherPi.py
WXLink Reset
------> See Readme to install tentacle_pi

GroveWeatherPi Solar Powered Weather Station Version 2.95 - SwitchDoc Labs

Then if I try to install the OLED manually and run the test scripts, I get this:

Traceback (most recent call last):

Hi buck western (great name by the way),

Check your installation instructions very carefully. Something isn not installed.

To eliminate another possibility, please run and post the test python script under the TCA9545 directory.

Also, check your TCA8545 (I2C Mux) to make sure you have installed the I2C bus power jumpers. Post a picture too!

did I not plug in the power jumpers correctly?

And your readout of the I2C busses look right too. It must be an installation problem. BP

You can also update and upgrade your Raspian OS, but I don't think that is the issue. BP

Look at your I2C mux output above. You can plug the OLED display directly into the Pi2Grover if you want to run that. Best, BP

I did everything from the top again and it seems to be working now. Thank you.

Hi - i got this OLED together with the weatherpi, It is not detected and it seems not turning on. Should i see a display or some light on it even if it is not detected?

thanks
Yul
