I am pretty new to ESP8266 and Arduino.
I am trying to use a reed switch that when reads high sends data to Firebase. I am able to connect to Firebase and able to get the code to set data in the Setup part of the code but it fails when it tries after the switch is high.
I have been working on this for over a week on and off and I have finally given up and seeking help. If anyone can help it would be greatly appreciated. Like I said, I am able to connect and set data in the Setup part so I know the wifi and Firebase info is correct. It's probably ugly, still learning and have been messing forever.
