Shelly 2.5 Roller Shutter

Hello, i have question, How can i convert button (100 - 0) to (open - close)

    Thing topic kitchen_roller_shutter "Kitchen Roller Shutter" @ "Kitchen" {
Channels:
    Type rollershutter : power       "Power"         [ stateTopic="shellies/shellyswitch25-004326/roller/0, commandTopic="shellies/shellyswitch25-004326/roller/0/command"]
}

Now when i click button i have:

shellies/shellyswitch25-0003FD/roller/0 -> 100
i need
shellies/shellyswitch25-0003FD/roller/0 -> close

you should join the Shelly Binding thread

In between the binding supplies a regular OH shutter control as well as a rollerpos channel with the inverted values
