Extract value from message

General
1

Hi,

I'm trying to figure out how to extract the value from following message:

"a100=16974\x03"

The value I want is the digits after the "=", but excluding the "\x03". The value can be 0 - 65535 (2byte)

I've tried to use $substring(payload,5,9) but of course this isn't suitable since there can be 1 up to 5 digits after the "=" sign.

If the \x will always be there you could do a split on the = then a split on the \x

3

Or determine the position of = and / by using the build in indexOf() function

Perhaps you have to add or subtract a 1.

Thank you, that worked great :smile:
