Find the Best Wi-Fi Channel Number You can use the ESP8266E which sits on the Wemos D1 mini as WiFi scanner to check which channel to use for your own home WiFi setup. You do not need any additional hardware to make the WiFi scanner. With the WiFi scanner you can check which WiFi channels are mostly used in your neighborhood, and with what strength they are.
