This sensor works in the UART mode, and you should connect sensors to UART pins (e.g., for CC2530 P0.2 – RX, CC2530 P0.3 – TX). Therefore, you cannot use the UART interface in the same configuration.

PZEM-004 V3

Please note that the firmware supports V3 only.

This sensor type supports the write command on the corresponding endpoint and allows you to reset the counted energy.
