Can't communicate with PZEM-004 module, how can I test if it works?
hello everyone,
this week got pzem-004 module , wanted test it, want use esp8266 connected directly board, returned -1 each value (v, w, wh) after trying on github couldn't make work.
to remove 1 of possible problems (esp runs on 3.3v, pzem 5v) tried flash arduino pro micro runs on 5v, , connect pzem 0v, if connected ac cable (nothing through coil, hould report tension , 0w power, 0v)
i used code found in forum , connected togheter no luck. alo tried swap rx/tx wires in case mounted them incorrectly
is there way somehow test pzem module ?
here video setup

is module dead? or wrong ?
any welcome.
