So, I have this Water Pumping system connected to the blynk server which monitors the water level and automatically pumps water if the water tank is empty. I have two esp32 and two water tanks which is located in different area of the building .The tank1 and the water pump is in the groundfloor. The tank2 is in the rooftop.
Now my problem is that the automation of the water pump is only applicable if it is connected to the internet (blynk server). I want my automation to continue even if there’s no internet connection using only the Wifi router for communication of two esp32.
