Any way to pull more data from OpenSprinkler Controller

I am building a drip irrigation system for my garden, while I do have OpenSprinkler for my grass I would like to use the watering level calculation from OpenSprinkler to input into my Drip System. Adding more zones is not an option due to the distance and other factors. Does anyone know how to get the OpenSprinklers calculated water level as an input to OpenHab?

I figured it out with the command

The output is:


Can someone help me in how to format it to pull out the second “0” after “wl”.
