Pi 3 Model B
So, I installed everything according to your directions. I open up the dashboard, either on the web or on Android. It sees my Pi. It may get a couple of readings, i.e. CPU, Network, etc. Then, when I want to do something, say add a relay, I get connection errors. When I want to change a GPU pin from input to output, I get "Error sending command." I have restarted my Pi no less than 15 times so far. I am absolutely getting frustrated here. I don't know if this issue is stated in another thread because there are way too many threads to read.
