Did you try with my pinout - i think it's same

Try with attached file

"P183-Voltage & Current (AC) - PZEM-004T" almost at the end of the list of devices

" Fotek ssr-25 da " from e-bay,... or similar

SSR relay ?

I'm interested - can you send me plugin ?
Also you can share public

Connect a resistor of about 10 KOhm from the connected GPIO to +3.3V.

Why not simply click "internal PullUp"

Same problem with : Wemos Lolin32
With Arduino IDE its OK .

Must have transistor ! - too little output current !

KY-005:
Operating Voltage 5V
Forward Current 30 ~ 60 mA

yes

Do you connect "VO" pin (contrast)

Hi! How to, the easiest way to add a PCD8544 plugin, to my Wemos D1 mini. I use this bin file ->ESP_Easy_mega-20181220_dev_ESP8266_4096. A small warning, I'm not a programmer :) Now i'm tray and work 8-) Just upload file from post #23 (firmware.rar - change extension from .jpg to . bin !!!) Connect...

I'm interested too.
I don't know why not include this small and cheap display to official release
