Hello, after 20 hours, it is solved, just do following: 1 - put '#' at the begining of lines 26 and 27 2 - clean '#' from the begning of lines 28 and 29 3- correct indentation of lines 28 and 29 4- wire pzem with rx2 and tx2 (16,17) 5- in "uPZEM_004t" body codes, replace line 44 with "counter_grid=uPZEM(2,pins=[16,17])" Good Luck
