# Door Monitoring

## Introduction

**Supported in:** [SimplePack 3.0/4.0 Plus Door or Full](/kb/simple-api-6-generation/overview/device-list/simplepack.md), [SimpleIndustry Door or Full](/kb/simple-api-6-generation/overview/device-list/simpleindustry-and-simplemeter/simpleindustry.md)

**Intended for:** End users and integrators & platform providers to understand device behavior before direct implementation and fine-tuning (for those who want to integrate the device into their own platform, the API 6 firmware documentation is [here](https://simplehw.atlassian.net/wiki/spaces/DOC/overview).

**Use case description:** For monitoring doors, we will use the SimplePack mode **Door mode**. The device behaves like this: You will receive a message whenever the door is moved. The device uses the magnetometer to determine change of orientation and picks up smooth movement (which the accelerometer struggles with sometimes). Simple, long-lasting and reliable. If you want to know the state of the door (open/closed), we suggest you use the reed switch in a reed switch mode.

## Prerequisites

Before-you-start checklist (you should have everything on the list if you went through the [first message guide](/kb/simple-api-6-generation/i-am-iot-platform-provider/first-message.md)):

✅ Hardware/devices\
✅ Sigfox connectivity\
✅ Sigfox coverage where you need it\
✅ IO Frog platform account and access\
✅ Correctly set-up callbacks in the Sigfox backend (if you're using your own connectivity)\
✅ [You're receiving messages from your devices](/kb/simple-api-6-generation/i-am-iot-platform-provider/first-message.md)\
✅ *Everything is fine!*

## Step-by-step setup guide

1\. Go to the IO Frog platform and **login** with your account.

2\. After you login, head over to your profile in the top right and make sure your Experience level is **Expert**, otherwise you will not be able to change device downlink - if necessary, increase your level and hit Update to save the changes.

3\. Go to the All devices tab and click on device **Setup**.

4\. In the downlink tab, set the mode to **Magnetometer mode** (0109 in the top bar), hit Update.

5\. Press the button of your device for 10+ (SP 2.0) or 6+ (SP 3.0 Plus) seconds, this will trigger downlink with the new settings - the **LED** will keep blinking for about a minute.

If you're working with the **SimpleIndustry** or the **SimpleMeter**, you need to either wait for the heartbeat that will request downlink (older prototypes) or you will use a **magnet** on the reed switch instead of pressing the button. The time of operation is the same (6s+ of magnet presence to trigger downlink, 2-4s to disarm device, 1s to arm).

| Device                  | Action                                                  |

6\. Once the LED stops blinking, you can place the device where you need it: use a heavy-duty double-sided tape to stick it to the door. Please note that if the door happens to be made of metal, it's preferable to use a 2-3 cm plastic spacer (read more in our [article about device placement](/kb/simple-api-6-generation/device/correct-device-placement.md)).

7\. Once placed, activate the device by pressing the button and try opening and closing the door to see if you receive the message right. *There, all done!*

Please note that Sigfox has a **90% delivery success rate**. It's possible that the downlink will not be received by the device, the best way forward in this case is simply **repeating the whole process from Step 4 onwards**.

## Suggestions

* If you're getting **false or limited reports** of usage, try playing around with **accelerometer sensitivity settings** (the higher the number, the less sensitive the sensor).
* If you're **losing a lot of messages**, set up **3x alert repetition**. This will better the performance of your device and you should lose less messages.
* **Public data sharing:** IO Frog also supports public channels, where you can add multiple devices and display data from all of them at the same time, including their position on a world map. It's very cool and we highly suggest you take a look! Here's our [coffee project](https://www.iofrog.com/public/iofrog/en/?channel=S2LZHUMFVQDNWFUM) and here's [how to set a public channel up](/kb/simple-api-6-generation/i-am-iot-platform-provider/public-channel-setup.md).
