EzloPi meshbot implementation for controlling four LED states using touch switch

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.

1. About this example

In this project, we have interfaced the EzloPi device with the 4-channel touch sensor module, which functions as four different switches for controlling the four LEDs. This will allow users to use both touch control and the MiOS smart application to remotely operate the four LEDs. In order to manage lights in a smart home setting, improve user experience, and boost energy efficiency, this project integrates hardware and software components in an approachable and user-friendly manner. EzloPi automation meshbot has been utilized in this project to automate actions such as the individual touch input as switches to control the state of the four individual LEDs.

2. Circuit Setup & Interfacing

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

ESP32 as an EzloPi smart device.
TTP224 4-channel digital touch sensor.
LEDs
100 Ohms Resistor

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 TTP224 module:

From ESP32 to 4 LED’s & Resistor:

3. Interfacing the 4-channel Touch sensor module using the EzloPi Web Flasher:

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

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

5. MiOS Mobile App

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

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

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.

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:

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:

After opening the MiOS mobile app dashboard, you will be able to see the tile of your connected device. The state of all the four LEDs can be controlled by just touching on the tiles for the touch inputs. Currently, all the tiles for the touch switch are OFF, which indicates that all the LEDs are OFF.

Here, as seen on the MiOS mobile dashboard, when the touch switches get triggered, they turn the LEDs on because of the rules we have set in meshbot.

Similarly, it can be seen that when we touch one by one on the 4-channel touch sensor module, the LEDs turn ON, also the tiles indicate that all four LEDs have turned ON because of the rules we have set in meshbot.
