# Simple Slider
The **Simple** slider is a horizontal bar you slide to set a **value**. It's the neatest of the three slider looks and tucks easily into a row of tiles.
## When to use it
Great for anything you set by amount where a side-to-side slider feels natural — a lamp's **brightness**, a dimmer **level**, or **volume**. Prefer a tall slider or a dial? See the [Vertical Slider](/dashboards/adding-widgets/control-widget/slider-vertical.md) or [Circular Slider](/dashboards/adding-widgets/control-widget/slider-circular.md).
## What you need first
* A device with a command on its **Commands & States** tab whose **input takes a number** (see [Setting up a command](/devices/commands/creating-commands.md)).
* A **Device metric** that reports the current value, so the slider shows where it's set.
## How to set it up
1. Open your dashboard in **edit mode** → **Add widget** → **Control**.
2. **Datasource** tab: pick the **Device** and the **Device metric** for the live value. Tap **Next**.
3. **Appearance** tab: type a **Widget name**, choose **Widget type → Slider**, then **Slider type → Simple**.
4. Set the **Command** it controls, the **Parameter** it sets, and a starting **Value**.
5. Add **Start and End labels** for the range (say `150` and `500`) and turn **Display** on; pick a **Slider color** and toggle the name/last-update line.
6. Tap **Save**.
## What happens when you use it
Sliding sends the command with the new value, the same way the device's States tab does. The handle follows the **Device metric**, so it shows the value the device is actually reporting.
## Common mistakes
* **Choosing a command that's only on/off** — a slider needs an input it can set to a number; for on/off use a [Switch](/dashboards/adding-widgets/control-widget/switch.md).
* **The range doesn't match the device** — set Start and End to the real lowest and highest values so the whole bar maps to values the device accepts.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.chirpwireless.io/dashboards/adding-widgets/control-widget/slider-simple.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
