Use a 4.7uF capacitor between D8 and GND (in your diagram above)
Now you still have AC voltage at the input.
If the measurement is performed close to zero Volt then the result is 0;)
The capacitor will equalize the oscillation (50-60HZ).
Your mains switches will be detected normally

It is a ITA-gz1-gl 100049de62.

This is https://www.itead.cc/wiki/Sonoff_SV not SSR!

Try with this fw. for Nokia5110

viewtopic.php?f=5&t=1685&p=34065#p32154

Use "global" NTP

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

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
