Magnetic Door Sensor Indicator

The EzloPi smart devices provide automation through simple, customizable use with our open-source EzloPi platform, making daily life easier and improving human-machine interactions.

Before moving into this example, it is very important to know about the device registration, provisioning and converting the ESP32 device into an EzloPi device along with knowledge of Web Flasher, MiOS Mobile Application for Android/iOS and the MiOS Web Application.

In this innovative Magnetic Door Sensor Circuit we will be Leveraging the power of EzloPi smart device by interfacing integrated magnetic door sensor, this circuit will ensure reliable detection of door status. Whether you're monitoring entrances for security purposes or creating an automated IoT ecosystem, our circuit delivers real-time feedback. With EzloPi smart devices you can trust in the efficiency and intelligence of our Magnetic Door Sensor Circuit for a heightened level of control and awareness in your spaces.

Welcome to the project demonstration video section. The following video showcases the key aspects of How to work with Magnetic Door Sensor Indicator on EzloPi platform, providing a visual walkthrough of its implementation.

The following components are required for interfacing with the EzloPi device:

• ESP32 as an EzloPi smart device.
• MC-38 Magnetic Door Switch.

The wiring diagram of ESP32 is represented as follows:

The following connections are made in order to complete the circuit setup:

From ESP32 to the MC-38 Magnetic Door Switch:

• Connect the 3V3 of the ESP32 with any one wire of the MC-38 Magnetic Door Switch.
• Connect the D4 pin of the ESP32 to another wire of MC-38 Magnetic Door Switch.

Set up your device/hardware by visiting config.ezlopi.com

2. Log in using the credentials which you just set earlier while signing up.

3. Now, click on the Connect Device button and a pop-up window will appear.

4. Now, select COM Port to which your ESP32 device is connected. In our case, the COM3 port is used.

Click Connect.

5. If you are new to this and it's your first time configuring, select Create new Device ID. Enter Wifi SSID and Wifi Password.
6. In the Device Configuration, tab click on Digital Input.

7. A Digital Input window will open for inputting the following parameters:

• Set a device name of your choosing. In our case, we set it to Door Sensor
• Set the INPUT GPIO input pin to 4.
• Set device Subtype to Reed Switch.
• Set the Resistor Setting to PULL DOWN.
• Then Click Apply Button.
• After clicking the apply button you can see a table of your setting in the device configuration tab.
• Press the Flash Device button.

15. A window will appear on the bottom right side of the screen displaying “Please press BOOT button while flashing begins.”

16. Hold the BOOT button down until the next window appears on the bottom right side of the screen which says “Installation prepared. Please release the boot button now.”

17. Release the BOOT button from your ESP32 when this pop-up on the bottom right window appears.

18. After some time, a popup will appear saying Device Flashed Successfully! This means that your device has been set up successfully.

You can download the MIOS Android app from the Google Play Store and Apple App Store.

1. After downloading the app, proceed to install the application and open it.

2. Using the MIOS mobile application, create a new Ezlo Cloud account using the sign-up option. If you already have an account, you may proceed to log in.

3. After successfully logging in, you will be able to see the number of controllers connected such as a lamp, fan, or any other device in the MiOS app. Tap on any controller of your desired ID:

4. You will be able to see the status of your controller whether it is online or offline. Access the device dashboard, and tap the device. The following view of the dashboard will appear:

5. After opening the MiOS mobile dashboard, you will be able to see the tile of your connected device.
6. As you can see in the example given above, we can see the Door Sensor tile. It shows a “Closed” message on the tile as the sensor is detecting that the door is closed.

7. Similarly, It shows an “Open” message on the tile when the sensor detects no magnetic fields.

1. After configuring the controller with the EzloPi web flasher, head to ezlogic.mios.com

2. Use the same credentials to log in that you used for configuring the controller with the web flasher.

3. Now, you will see a tile labeled as Reed switch on the MiOS web application dashboard. Currently, As you can see above, It shows a “Closed” message on the tile as the sensor is detecting that the door is closed.

4. Similarly, It shows an “Open” message on the tile when the sensor detects no magnetic fields.
