GE Smart Dimmer 12724 - No Slider or gradient/smooth brighten or dim

I am having issues with the GE Smart Dimmer 12724. The dimmer turns on at about 25% brightness and will not go any brighter until manually done from the switch. Also, the dimming functionality does not work. The lights can only be turned on or off, no dimming.

Please help!

Here is my following configuration:

Default Items:

Dimmer Light_Living_Room “Living Room [%s %%]” {zwave=“5:command=Switch_Multilevel, restore_last_value=true, refresh_interval=30, respond_to_basic=true”}
Dimmer kitchen_dimmer “kitchen Dimmer [%s %%]” {zwave=“4:command=Switch_Multilevel, restore_last_value=true, refresh_interval=300, respond_to_basic=true”}


import org.openhab.core.library.types.DecimalType
import org.openhab.core.library.types.*
import org.openhab.model.script.actions.*
import org.joda.time.DateTime

var int percent = 0
var Timer fade_Timer = null

rule “Dimmer Light”

if (Light_Living_Room.state instanceof DecimalType) {
    percent = ((Light_Living_Room.state as DecimalType)/5).intValue * 5 //round to 5
    fade_Timer = createTimer(now.plusMillis800)) [|
        if (percent > 0) {
            percent = percent - 5



sitemap default label=“Main Menu”

Frame label="Home" {
    Text label="Home" icon="attic"
        Frame label="Living Room"{
            Slider item=Light_Living_Room 
            label="Living Room Lights" 
        Frame label="Kitchen Dimmer"{
            Slider item=kitchen_dimmer 
            label="Kitchen Dimmer" 


Please help!!

Thanks in advance
