I don’t know how to ask this question … sorry
I’e got ESP with IR for remote control my old audio player. Now I can send properly all codes . I created items for ON/OFF, MUTE etc. but I’ve got problem with volume . I would like use dimmer with stepper list widget . I need only - and + value between isn’t important.

When we use switch we need 2 values ON and OFF but how I should name VOL+ and VOL- to use it with this widget ?

My item is normal string with state description

ON=ON
OFF=OFF
MUTE=MUTE
VOLUP=VOL+
VOLDOWN=VOL-
CHUP=CH+
CHDOWN=CH-

The stepper widget just cannot be used for this. By design, it only works with numbers, it will not work with increment and decrement commands. It’s not a matter of changing the commands that this item receives, there’s just no way to get a stepper to send the string type commands that your IR item needs.

You can look at this recent thread for a very similar question and an example of how to create a widget that looks like the stepper widget but will actually send arbitrary string commands:
