Presence Alert with email notification using Touch Sensor

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.

This project aims to interface a TTP223B Touch Sensor with the EzloPi device for efficient detection of the person on the chair. The TTP223B Touch Sensor is a simple yet effective touch sensor, which is integrated with the EzloPi device to enable real-time monitoring of the certain individual if he/she is available or not. This smart monitoring is done by utilizing the MiOS smart platform for allowing the users to monitor and notify them about the presence Alert. Subsequently, the user is notified via email when someone gets available.

By utilizing the EzloPi device, we can integrate this smart system into our office setups or as part of a larger project.

Welcome to the project demonstration video section. The following video showcases the key aspects of Presence Alert with email notification using Touch Sensor, providing a visual walkthrough of its implementation.

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

• ESP32 as an EzloPi smart device.
• TTP223B Touch Sensor.

The wiring diagram of ESP32 30 pin is represented as follows:

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

From ESP32 to the Float Switch:

1. 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 Touch Sensor.
• Set the Input GPIO to 4.
• Set Device Subtype to Touch Switch (Toggle) TTP223B.
• Set Resistor to PULL DOWN.
• Set Default Value to LOW.
• 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.

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

9. 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.”

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

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

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

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

3. As seen in the MiOS web dashboard above, the Touch Sensor tile is visible. For now it is not yet triggered.

MeshBots:

4. On the right side of the screen under Automation, click on MeshBots.

5. On meshbot screen, click on Create new MeshBot button present on the top right corner of the screen.
6. After clicking on Create new MeshBot you will see new options, now under Notification MeshBot click on Create.

7. On the next screen you will see that we can create a name of our choosing, in this case we write it as Test001.

8. In the trigger tab you can set the TRIGGER for your device and in the ACTION tab you can set the action to be performed based on the trigger which you have created.

9. Set these values in TRIGGER section:

• Set Node Type to Device.
• Set the Node to Touch Sensor.
• Set the Capability to Switch.
• Set the value to True.

10. Set these values in the ACTION section.

• Set Controllable Type to Notification.
• Set the User to Your user account .
• Set the Channels to email,push.
• Set the Subject to Presence Alert.
• Write the suitable Message body that you want to receive in your email. As you can see, we write, The Person has sat on the chair.
• After clicking the apply button you can see a table of your setting in the Current configuration tab.

11. After clicking the save button you can see this screen on the top right corner of the screen.

12. Here you can see your saved MeshBot. Now click on Dashboard.

13. As seen in the MiOS web dashboard above, When the Touch Sensor gets triggered, the tile will be updated and show the message “ON” and also an email sent to the user as seen below.

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 dashboard, you will be able to see the tile of your connected device.

6. As seen in the MiOS web dashboard above, the Touch Sensor tile is visible. For now it is not yet triggered.

7. As seen in the MiOS web dashboard above, When the Touch Sensor gets triggered, the tile will be updated and show the message “ON” and also an email sent to the user as seen below.
