I use WeMos D1 Mini and use 2 Pzem which I connect to pin D5-D8 and some other sensors on pin D0-D3 when starting boot must disconnect the pzem from the pin, otherwise the system will not work

Hi this is not a issue because wemos as others esp8266 devices fail to boot if D8 is left high at boot . Best pins are D1 D2 D5 D6 D7 . Also I don't recommend to use D0 as it is the wake pin and is pulled high at boot .https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/
