This is an AWESOME tutorial, thank you. Could you help me? I am using wifiManager and FS.h and ArduinoJson with ESP8266-01 to enter new IP address and Password. This works great. I also create a custom parameter (thingSpeak Write API, apiKey[20]="";) which is entered on the same page as the IP and Password and it is supposedly saved to a SPIFFS file. Once my upload is finished everything connects to the wifi and thingSpeak and uploads my sensor info. However if the power to the ESP is interrupted then I can get the ESP to reconnect but it doesn't upload sensor data anymore. How do I access the SPIFFS data and copy the (thingSpeak Write API) to char apiKey[20]=""; so it can continue uploading information.
