Using moitessier hat and GPIO

[Ranur]

So with some of the brain trust collected as contributors in this thread, I'll continue to post some of my newbie questions here. I decided to go with  SigkSens and installing the shabang went smooth. No warnings or any red text whatsoever when compiling. BUT when I get here: https://github.com/mxtommy/SigkSens/wiki...k-settings, the D1 mini does not show up on my network. Any idea why? I am stuck!

Edit: It might have been that I had left out the SPIFF - troubleshooting..

Need help with an SigKSens issue. I have two D1 Minis. Got the SigK loaded over to both of them end everything was grand and dandy. But then (I KNOW -if it's not broke don't fix it right?) I decided to change the input data types of one of them. So I soldered the MPU 9250 to the D1, made the changes in the config.h acordingly and reflashed. 
My fiorst problem was a very unstable connection to the "Unconfigured Sensor" with lots of attempts to set it to the home wifi. Secondly, it shows in the serial terminal in Arduino that it checks onto the the network, but it never quite makes it. Instead I get the following msg:
: 10.10.10.157
Connected to Wifi!
reading config file
opened config file
Current Configuration:
{}failed to load json config


I have tried to reflash it a couple of times, but with same result. So question from a newbie is. Have I toasted my D1 mini, OR might it be because the MPU 9250 is connected before the unit is properly configured that I get these problems. Any assistance highly appreciated. 
Oh and merry Christmas to y'all!
