Control multiple lights with just one tap using EzloPi MeshBots

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 will interface four AC lamps with the EzloPi device by utilizing a 4-channel relay module which will perform as a switch for the lamps. This will enable users to remotely control the four AC lamps using the MiOS smart application. With just one tap, we can control the state of all the AC lamps. This project combines hardware and software components to provide a user-friendly and easy-to-use solution for managing lighting in a smart home environment and ultimately enhancing the user experience and increasing energy efficiency for our smart home.

With the EzloPi meshbots, we can set certain rules and actions according to our requirements and automate these tasks to perform certain actions which would fulfill our smart home requirement.

2. Project Demonstration Video

Welcome to the project demonstration video section. The following video showcases the key aspects of How to control several AC lamps with one tap using EzloPi Platform, providing a visual walkthrough of its implementation.

3. Circuit Diagram & Interface

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

ESP32 as an EzloPi smart device.
4-channel 5V relay module.
4x AC lamps with holder and AC wire.

The wiring diagram for ESP32 is represented as below:

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

From ESP32 to the Relay module:

From Relay module to 220V AC Lamp and Main AC supply:

4. Interfacing the 4-channel relay 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.

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

Click Connect.

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

A Digital Output window will open for inputting the following parameters:

Set device name to Relay_IN.
Set Device subtype to Relay.
Set OUT GPIO to 18.
Set Resistor to PULL UP.
Set the default value to LOW.
Then Click Apply Button.

Again in the Device Configuration, tab click on Digital Output.

A Digital Output window will open for inputting the following parameters:

Set device name to Relay_OUT1.
Set Device subtype to Relay.
Set OUT GPIO to 5.
Set Resistor to PULL UP.
Set the default value to LOW.
Then Click Apply Button.

Again click on Digital Output:

Set device name to Relay_OUT2.
Set Device subtype to Relay.
Set OUT GPIO to 4.
Set Resistor to PULL UP.
Set the default value to LOW.
Then Click Apply Button.

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

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.”

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

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

4. MiOS Web Application

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

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

On the MiOS web dashboard, you will be able to see the tile for four relays, one for controlling and the other three are for output. These three relays will indicate the status of the first relay.

MeshBots:

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

On meshbot screen, click on Create new MeshBot button present on the top right corner of the screen.

After clicking on Create new MeshBot you will see this now under Automation MeshBot click on Local.

On the next screen you will see that we can create a name of our choosing, in this case we write it as Test003.

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.

Set these things in TRIGGER section:

Set these things in TRIGGER section:
Set Node Type to Device.
Set the Node to Relay_IN.
Set the Category to Switch.
Set the value to True.

Set these values in the TRUE part of the ACTION section.

Set Controllable Type to Device.
Set the Controllable to Relay_OUT1.
Set the Capability to switch.
Set the Value to true.
Add an ACTION again.
Set Controllable Type to Device.
Set the Controllable to Relay_OUT2.
Set the Capability to switch.
Set the Value to true.
Add an ACTION again.
Set Controllable Type to Device.
Set the Controllable to Relay_OUT3.
Set the Capability to switch.
Set the Value to true.
Now Click the Save button.

Set these values in the FALSE part of the ACTION section.

Set Controllable Type to Device.
Set the Controllable to Relay_OUT1.
Set the Capability to switch.
Set the Value to false.
Add an ACTION again.
Set Controllable Type to Device.
Set the Controllable to Relay_OUT2.
Set the Capability to switch.
Set the Value to false.
Add an ACTION again.
Set Controllable Type to Device.
Set the Controllable to Relay_OUT3.
Set the Capability to switch.
Set the Value to false.
Now Click the Save button.

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

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

After opening the MiOS web dashboard, you will be able to see the tile of your connected device. The state of all the four AC lamps can be controlled by just touching on the tiles for the lamps connected to the relay modules.
Currently, all the tiles for the relay are OFF, which indicates that all the AC lamps are OFF.

Similarly, it can be seen that when the first relay is ON, it indicates that all four lamps are ON.

5. MiOS 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 AC lamps can be controlled by just touching on the tiles for the lamps connected to the relay modules.
Currently, all the tiles for the relay are OFF, which indicates that all the AC lamps are OFF.
