Hey - first of all, I hate it too & never really understood why it is so important. (Until now.)
The Settings on the Awtrix Server have no Form Input Type Validation.
I somehow someday accidentally & unknowingly entered/copied a String into the Brightness option field and saved it.
Which bricked my AwtrixMatrix to the point that it did not connect to the server anymore.
Today I decided to fix and search for the problem. The log was telling me about a RuntimeException because of an input string, id of course not recognize. And before I almost reinstalled the entire Server I spotted text in the brightness field. (duh Stupid Me).
A case where simple Form Validation could have saved me a good amount of time. 😃
So, please 😃 for future users who maybe only half as stupid as me.
Could you add the half a line of code 😃 Strings to Strings and Ints to Ints
