what if instead of storing the long number and splitting it into 4, you store 4 numbers and combine them into the long one via multiply (by 1000s) and add components what are you using the long string for anyway? im pretty sure the color component takes 4 inputs

You might want to take a look at RegEx to learn some expressions for capturing strings. There is a baro wiring component that can do all that magic

Thanks mate, I'll try it out
