Configure Logitech Harmony Hub Volume Control as a Dimmer Switch

I need help configuring my Logitech Harmony Hub volume control as a dimmer switch.

Currently, I can control my volume up/down of my receiver using a simple button command in the item/sitemap. However, I find it very cumbersome if I want to increase the volume by 2 notches. Is there a way to configure my volume control within Openhab as a dimmer switch? (so each 25% increments increases or decreases the volume by 2 or more)

Also, how would this translate when I program it within the Amazon Echo HA Binding configurator (onURL and offURL)?

Any help is appreciated.

I found some similar posts here in the forum and it seems like I need to create a rule in addition to inputting the item and sitemap code, but I don’t understand. My knowledge in programming is pretty limited coming from a graphic design background, but I know how to get around things or tinker my way out of something.

Thanks again for your help.

I would love an answer to this as well, as I’m in the same boat!

Also Justin, would you mind pasting your line for the volume buttons from your items file?

Thanks.
