*IMPORTANT* PLEASE EDIT THE WI-FI SSID FOR THE FEW BLOCKS BEFORE YOU START USING THIS FLOW TO MAKE IT WORK
Switches to another Wi-Fi when signal is lower than 60% if you have 2 Wi-Fi with different SSID. Feel free to comment below if any problem is found. You can also edit the blocks in this flow anyway you want. I'm currently working on the part which switches to data connection when the two Wi-Fi networks not in range.
