Hot wire IN and Hot wire Out, that is it! The small blue wire need to connect with Neutral wire, I guess this is for the Smart breaker to operate with power for Wifi connection. This is the easiest way to convert one wire to smart/wifi/Alexa controllable.Forget about DIN compatible as this small guy can easily sit in anywhere inside the breaker box.Also no need to worry about Wifi signal issue as mine sit in the metal box w/o any problem for connection.The reason why I am doing this small project is: My pool control box is on my bedroom outside wall which always has buzz noise because of the transformer inside, which may bother my sleeping. So I use this breaker can automatically turn it on in daytime and off in night.One more thing for the wifi connection: Metal box need a little gap when closing, that will be enough for wifi connection, if tightly closed, it may have wifi connection issue.
