@TrDA-hab I'm afraid your schematic for "PZEM-004 PCB boad x3 phases" is wrong |

For PZEM-004t v.3 i.e. according to this scheme, I set the TX and RX in tasmota to the GPIO4(D2) and GPIO5(D1) pins, right? |

Nie próbowałem.
Buduje łucznik ESP + 3x PZEM 004 i działa Ok.
Nie próbowałem 4 x PZEM 004

Why do you think that it is necessary to replace R4 and R8 for correct operation at 5V? Countless users are using these without that mod. |

The ESP chips are not specified to be 5V-safe, contrary to a widespread myth. |

Oh, so the 5 V mod is for using 5 V power but 3.3 V TTL? This doesn't seem right. |

I have PZEM 004 modules connected to ESP8266 and I have SP111 sockets. I
updated from version 10 to version 13 and noticed the problem.
After reset - turning off the ESP power supply, the EnergyToday
indications are reset to 0.00. Yesterday the power was turned off at 10
p.m. and the readings for the entire day were reset, i.e. EnergyToday
0.00, which was not added to EnergyTotal.
So today I disconnected the power supply from the ESP and, as it says,
the EnergyToday reading showed 0.00

Ok, so you need to provide emergency support for the ESP module itself.
Do all versions work this way?

Working as designed
Energy Today is added to Energy Total at midnight
If you cut power before, you'll loose the data
Tasmota is not meant to loose it's power on regular base. Keep it on to get it working as expected

This is the way tasmota works. Designed to be powered 24/7 |

I have another question: Why, when I insert Tasmota into Sonoff 4ch and after configuring it, when I press the button on Sonoff, the relay goes to the relay with a delay of about 1-2 seconds?

For planned outages, you can also choose to save the current consumption data, command SaveData or Restart. Data is also saved if settings/status is saved for other reasons, but not at regular intervals, except midnight.

In my case, the power plant often has short 230V outages, i.e. the power outage lasts 1-2 seconds, so I need to provide UPS backup for the Tasmota modules. Yesterday there was a blackout after 10 p.m. and the energy data collected from the entire day was discharged and was not added to the total.

Try connecting the pzem004 to your PC using an FTDI adapter. There is a tool on the pzem manufacturer's website. where you can adjust everything possible such as the measured values or bus addresses. Greetings Basti
