 Cut the power cable in two and connect the input wires to both Sonoff Basic and PZEM-004T. Route one of the power output wires through the PZEM-004T core and connect the output wires to the Sonoff Basic output.
 
 As most parts are connected to high voltage AC it is recommended to fit the hardware in a solid enclosure.
