I'll setup smart config (OTA configuration) for your arduino device, so that you can always configure your device Over The Air(OTA). By enabling smart config in your WiFi enabled device, it will scale your device to be configurable without being taking it out from the place where it is installed and code it manually. The advantages of SmartCofig are: All the above values could be changed/configured over the air on your mobile phone by connecting to the hotspot created by your wifi enabled ESP/Arduino device. Feel free to ask questions before your order. Thank you.
