Wifi Configuration

When you have uploaded your code, and the device starts up for the first time, it will spit out a bunch of messages saying it can't find a saved wifi network. Let's fix that!

For your MicroIndicator to download the latest data, it needs to connect to the internet through your wifi. To give it the wifi password, connect the hotspot it just created.

In the above case, it's called ESP_F6129C, and it'll open a captive portal when you connect:

If it dosen't automatically pop-up for you, just go to http://192.168.4.1/ in any web browser.

If you connect sucessfully, press Configure Wifi:

Then, you can click your Wifi network in the scan results, enter your Wifi Password, and save.

If your wifi network dosen't show in the scan results, it might not be supported by the NodeMCU, please ensure the wifi network has 2.4Ghz support, and your NodeMCU is close enough to the router.

Once saved, hopefully it will connect!

If it can connect back to the DirtyWatts Server, it'll start spiting out stats about the powergrid:

If it dosen't and instead fails to connect to the server, it could be beacuse of many reasons. It might be due to an captive portal on the wifi blocking acess, in which case you will need to find a diffrent wifi network, or it could be that the Dirtywatts API is offline for everyone!
