@ogiewon I will continue to praise your efforts for this project, I have found so many ways to make use of this, many thanks!!
I recently changed wifi networks at home so I needed to update a d1 mini board for a PWM project I implemented years ago and never changed since(Link to post). When using it last i noticed that when setting the level around 25% the SSR I had attached to would just be full power not "dimmed" like it was between 0-99 (like the PWM project specifies).
After a bunch of digging and AI help I found that the ESP8266 D1 Mini boards I am using changed the PWM resolution on the core board from 0-1023 to 0-255, effectively making anything above 255 at 100% (I think I am explaining this correctly!?).
The Fix
To fix this I had to modify the EX_PWM_Dim.cpp and replace the following in 4 different places:
analogWrite(m_nPinPWM, map(m_nCurrentLevel, 0, 100, 0, 1023));
with
analogWrite(m_nPinPWM, map(m_nCurrentLevel, 0, 100, 0, 255));
I'll admit I understand logically at a high level how this all works, but I do not understand how each part works exactly, nor do I understand how to code. So while this solved my issue for now, I believe that this is more of a bandaid than a permanent fix of the PWM component due to the way the core for these ESP8266 board changed. So I am elevating to this group to see if there is someone out there that would be willing to look at and re-write the PWM component to factor in the new 1023 resolution?
Again for give my mistakes if there is anything that i misspoke or mislabeled in this post 
. Happy to chime in more if there is anything that needs clarified.
