Serial port multiple items

I’m trying to send commands and receive data to my Solar inverter , currently I’m using a perl script to write to mysql database.
I’m attempting to set up a bridge for the various metrics from my inverter
eg ON/OFF / kWh today, power-in/out.
however all the data is individually collected eg I send command INV ; response {on|off} KWHTODAY ={energy produced}

How do I set up a Thing and rule to collect all these items individually as I don’t want all items to be updated when I send a command for one item.

eg logically like the below

Bridge serial:serialBridge:solar [serialPort="/dev/ttyS0", baudRate=9600 ] {
    Thing serialDevice xantrex_inverter [patternMatch=".*"] {
        Channels:
			Type switch : inverter_status [command="INV?"]
            Type number : power_in [commandFormat="PIN?"]
            Type number : power_out [commandFormat="POUT?"]
			Type number : kwh_today [commandFormat="KWHTODAY?"]
			Type number : kwh_life  [commandFormat="KWHLIFE?"]
    }
}

You can use a regex transformation to only match against the data appropriate for that Channel. For example

REGEX:(.*KWHTODAY=.*)∩.*?KWHTODAY=(.*)

The first REGEX matches the whole string only if KWHTODAY is present in the String and the second REGEX extracts just the value.
