Pzem 004T v3 Energy reset

Hi, I’m trying to reset the energy of my three pzem but it doesn’t work. The log indicates the button is pressed but the energy does not reset.

Any (verbose) logs?

do you mean I have to set the logger to verbose?

Perfect !
My pzem-004t code use double sensor ;
1: 2 second sample no register database
2 : 60 second register database

What are the advantages of using slow sensors?

The sensor that updates quickly is only used to display the data, some appliances in the house have strange behavior, and you see every behavior. The slowly updating sensor is used to record data in the database and not fill it with data.
