For a rotary encoder use this one.
Myself I’ll use rotary encoder type KY-40.

# Rotary Encoder II Plugin
___by 7h0mas-R___

This is an alternative implementation of a rotary encoder driver for integration with Volumio. It dynamically loads device tree overlays to access the rotaries and is more responsive with the tested encoders than the existing plugin.
