How get text sensor value to subtract into two parts ?
Value is “A 1234” and i want only 1234 part remain, how can it be done?
Is it possible via Filters?

What patterns are always present and how do you want to process it?

E.g do you always want all text after the first space?

Or do you want to strip out all non numeric characters etc?

If you want to split on a separator you’ll likely use a lambda similar to the one here:

[How to] UART read without custom component

The UART Bus component provides a write action but no read actions. Typically the UART read is implemented in a custom component that also does the processing. The UART debug sequence can be exploited to act like a call back function whenever there is received data to process. So basically instead of creating a small custom component a large lambda call can be used in the UART debug yaml. This is shared to hopefully help make implementing UART devices a bit easier for average users. It seems t…

Key parts being sscanf.

found one easy way
filter and replace to nothing

        filters:
         - substitute:
           - "A -> "

That will not do anything to A 1234

[mortenx]

“A 1234” + filter = result “1234”

        filters:
         - substitute:
           - "A -> "

Is the character to be filtered always “A”

If so, why post the answer as involving “Z”?
