I have a device (Smartmeter) that sends strings.
All strings start with a number, for example 0-1:96.1.0 and then a value (1234.56*) and ends with carriage return
The smartmeter does sometimes send carriage return before the value is transmitted.
I filter most messages with the switch node using [string contains 0-1:96.1.0]
But how do I get the one string that doesn't start with 0-1: ?
Is there a function or something that does: [string does not contain 0-] ?
