the first bug fixed by removing delay in my while loop, turned out the delay line will cause error.
for the LCD, im trying to remove / uninstall the library and install a fresh new library and reconnect it.
it wasn't that it show all aliens kind of characters,
but when the lcd clear code fires, then there's where the weird characters appear on screen
im suspecting that there's a spike of current? but will be concluded after 2-3 library change
Which boards package are you using for the WeMos D1? I was under the impression that the ESP8266 variant of delay() called yield() and would not cause a watchdog timer reset.
I am still of the opinion that calling scale.begin() multiple times is going to cause you problems.

Im suspecting the LCD library works with 18 chars as previous code was initated with 16
and the average value taking from scale.get_units(5), it turned out the whole script will turn haywire if bigger average is set (Eg: 5 to 20)
The serial thrown the same error again when scale code should run.
I tried installing Exception decoder in my mac by creating tools folder and extracting the downloded jar file.
but when i closed IDE, compiled and ran the code: the Exception decoder not even showing in Tools menu on top of IDE
I don't know. I never use tools like the exception decoder. When I get something like that, I start examining the code, starting with the last change I made to it before it started happening.
