:::note
This plugin requires attaching a peripheral accessory to your device. It will not work without one.

## Overview

Meshtastic supports hardwired rotary encoders as input devices.
Currently, one rotary encoder (`rotary1`) is defined, but later more rotary encoders
can be added (if needed) the same way.

:::tip
Once plugin settings are changed, a **reset** is required for them to take effect.
