ESP32 and PZEM-004T v3 working intermittently

PROBLEM DESCRIPTION

I have connected a PZEM-004t-v3 to ESP32 (Tasmota 13.4.0(solo1)). R8 where lowered.

It works intermittently for few hours, then it display all zeros in the energy fields. I have double-checked the wiring and it is consistent. I am using hardware serial and connected PZEM to ESP's RX/TX GPIOs.

When not displaying energy data, there is no error in WebLog 4.
