Just reviewing the startup instructions: http://www.dexterindustries.com/GrovePi/get-started-with-the-grovepi/
I had no problems connecting with SSH, but I was writing down what I did for someone else and in so doing I found the instructions on that page for Part 3, step 6:
Open a web browser on your computer and in the address bar, type “http://dex.local”, and hit enter. Note: If you are using a touchscreen laptop, please use Firefox, as certain vital features will not work in other browsers.
First off, I think you changed to raspberrypi.local in your distribution. But neither of those addresses caused anything to happen when I pointed my web browser at them (dex.local was not resolved, and there was no response at raspberrypi.local). Do these pages require updates or did I fail one of the steps.?
