Create staircase lighting solution using LED and two buttons

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

The goal of this project is to create a simple and easy lighting solution for controlling the staircase light using two different buttons present on two different floors using the EzloPi device. This will enable users to also remotely control the LED light using the MiOS smart application. This project combines hardware and software components to provide a user-friendly solution for efficiently managing lighting in a smart home environment and ultimately enhancing the user experience and increasing energy efficiency.

2. Project Video Demonstration

Welcome to the project demonstration video section. The following video showcases the key aspects of Create staircase lighting solution using LED and two buttons, providing a visual walkthrough of its implementation.

3. Circuit Setup & Interfacing

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

ESP32 as an EzloPi smart device.
XY-MOS, high-power dual MOSFET driver module.
Mini portable lamp (24 LEDs).
12V External power supply.
Push buttons.

The wiring diagram is represented as follows:

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

From ESP32 to the MOSFET driver module:

ESP32	MOSFET driver
D5	Trig
VIN	VIN+

From MOSFET driver module to LED Strip:

MOSFET driver	24 LEDs Strip
OUT+	5V
OUT-	GND

From ESP32 to the Push Buttons:

ESP32	Push Buttons
D15	1st Terminal (Push Button1)
3V3	2nd Terminal (Push Button1)
D5	1st Terminal (Push Button2)
3V3	2nd Terminal (Push Button2)

From External Power Supply to MOSFET Driver Module:

External Power Supply	MOSFET Driver Module
VCC	Supply+
GND	Supply-

4. Interfacing the LED & Resistor using the EzloPi Web Flasher

1. 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 Input.

A window will open for inputting the following parameters:

Set a device name of your choosing. In our case, we set it to Ground Floor.
Set OUT GPIO to 5.
Set Device subtype to Digital In Switch / Button / Key.
Set Resistor to PULL Down.
Set the default value to LOW.
Then Click Apply Button.

Again click on the Digital Input button for interfacing the second button.

A window will open for inputting the following parameters:

Set a device name of your choosing. In our case, we set it to First Floor.
Set OUT GPIO to 15.
Set Device subtype to Digital In Switch / Button / Key.
Set Resistor to PULL Down.
Set the default value to LOW.
Then Click Apply Button.

In the Device Configuration, tab click on Digital Output.

A window will open for inputting the following parameters:

Set a device name of your choosing. In our case, we set it to Ground Floor.
Set Device subtype to LED.
Set OUT GPIO to 4.
Set Resistor to PULL UP.
Set the 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.

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.

5. MiOS Web Dashboard

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.

After opening the MiOS web dashboard, you will be able to see the tile of your connected device. The state of the LED light is controlled by just touching the tile buttons as shown on the app.

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 new options, 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 Test001.

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 Ground Floor.
Set the Category to Switch.
Set the value to True.
Add another trigger by clicking Add Trigger.
Set Node Type to Device.
Set the Node to First Floor.
Set the Category to Switch.
Set the value to True.

In the True part, Set these values in the ACTION section.

Set Controllable Type to Device.
Set the Controllable to Light.
Set the Capability to Switch.
Set the Value to true.

In the False part, Set these values in the ACTION section.

Set Controllable Type to Device.
Set the Controllable to Light.
Set the Capability to Switch.
Set the Value to false.

6. 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 the LED Light is controlled by just touching the tile buttons as shown on the app.

Now, we can see that when the light is operated from the first floor button, the light turns on because of the rule we have set in the meshbot.

Now, we can see that when the light is operated from the ground floor button, the light turns on because of the rule we have set in the meshbot.

6. MiOS Web Application

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

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

After opening the MiOS mobile app dashboard, We can see that when the Light is operated from the First Floor Button, The Light turns on because of the rule we have set in the meshbot.
