> ## `WARNING: Only compatible with Raspberry Pi`

\#####Do not enable or attempt to install on any thing other than a Smart-Mirror compatible Raspberry Pi Device.

#### Installing Dependencies

Motion Detection requires Johnny-five.io as well as Raspi-io.

make sure you're within the smart-mirror folder.

```bash
cd ~/smart-mirror
```

from the smart-mirror folder run the following command.

```bash
npm install johnny-five && npm install raspi-io
```

#### Configuration

Use the Motion Settings of the ConfigUI to configure and enable the motion detection after installing dependencies.

| Variable | Usage                                                                                                   | Data Type | Default Value if not included in config.js |
| -------- | ------------------------------------------------------------------------------------------------------- | --------- | ------------------------------------------ |
| pin      | Identify GPIO input Pin connected to output pin of the PIR device or other device used to detect motion | string    | GPIO26                                     |
| enabled  | enable motion detection                                                                                 | boolean   | false                                      |

#### Making it all work

**Parts required**

* [PIR Device](https://smile.amazon.com/gp/product/B00FDPO9B8/ref=oh_aui_search_detailpage?ie=UTF8\&psc=1)
* (optional!) LED (color of your choice)
* (optional!) Resistor (based on draw of LED)

#### Basic Functionality

Motion detection works with AutoTimer Settings. Using Johnny-Five's motion API the PIR device is connected to a PIN on the Raspberry Pi. Suggested PIN is GPIO 26 as illustrated in figure 1 and figure 2 above. When the `motionstart` event is triggered the `auto-sleep timer` is stopped and will remain stopped until the `motionend` event is triggered. When the `motionend` event is triggered the `auto-sleep timer` is started and set to the `config.autoTimer.autoSleep` interval set in configUI.

#### Issues

A live chat to get help and discuss mirror related issues: [discord chat](https://discord.gg/EMb4ynW). Usually there are a few folks hanging around in the lobby, but if there aren't you are probably better off [filing an issue](https://github.com/evancohen/smart-mirror/issues/new). Please tag @justbill2020 on any motion detection issues.
