In today's fast-evolving IoT and smart hardware landscape, a smooth and responsive user interface (UI) has become just as important as core functionality.
M5Stack, continuing to refine its visual programming platform UIFlow2, now officially integrates the powerful LVGL (Light and Versatile Graphics Library) — giving makers and developers the best of both worlds: the speed of visual programming and the freedom of a professional embedded GUI framework.
UIFlow2, built on MicroPython, is designed to lower the barrier for hardware programming. Earlier versions included basic controls and drawing functions — useful for simple projects but less suited for complex UI needs.
LVGL changes the game. It's an open-source, lightweight, cross-platform embedded GUI library with:
With UIFlow2's LVGL integration, developers can start by dragging and dropping blocks, then fine-tune behavior via Python code — moving seamlessly from beginner-friendly to pro-level control.
What's Available Now
UIFlow2 already supports LVGL in its first integration phase:
Whether you're a first-time maker or a seasoned embedded engineer, you can design and deploy interactive UIs faster than ever.
Getting Started in 4 Steps
1. Launch UIFlow2 Web IDE
Power on your M5 device and connect to the UIFLow2 online editor.
2. Enable LVGL Support
Select M5UI in settings to enable related blocks.
3. Add Widgets or Write Code
Block Mode: Drag and drop "Button", "Label" and other controls directly.
Code Mode Example:
import m5ui
import lvgl as lv
import M5
M5.begin()
m5ui.init()
page0 = m5ui.M5Page(bg_c=0xffffff)
button0 = m5ui.M5Button(
text="click me",
x=115,
y=153,
bg_c=0x2196f3,
text_c=0xffffff,
font=lv.font_montserrat_14,
parent=page0
)
label0 = m5ui.M5Label(
"Hello M5!!!",
x=123,
y=82,
text_c=0x000000,
bg_c=0xffffff,
bg_opa=0,
font=lv.font_montserrat_14,
parent=page0
)
page0.screen_load()
After downloading the program to the device, controls will immediately display on the screen and support real-time interaction.
What's Coming Next
We're pushing towards full LVGL integration and a more intuitive design experience:
Ultimately, UIFLow2+LVGL bridges the gap between quick, beginner-friendly prototyping and precise, professional-grade UI development — giving every creator the speed to start and the depth to go further.
If you’re just getting started with Home Assistant, one of the easiest and most fun projects to try is smart lighting. This guide walks through how to set up the M5Atom Lite—a compact ESP32-based module—as a smart RGB light controller, fully integrated with Home Assistant using ESPHome.
What You’ll Need
Before we begin, make sure you have Home Assistant installed. You can follow the official documentation for your preferred platform.
Once Home Assistant is up and running:
2. Adding the Device
1. Open the ESPHome sidebar and click NEW DEVICE in the lower right corner.
2. Click CONTINUE when the setup screen appears.
3. Name your device (e.g., Atom-Lite), then proceed.
4. On the device type screen:
o Uncheck Use recommended settings
o Select ESP32 → choose M5Stack-ATOM
5. Click NEXT and copy the encryption key that appears.
6. Choose Manual download to begin compiling the firmware.
Back on the ESPHome dashboard, you’ll now see your new Atom-Lite device listed.
1. Click EDIT to open the YAML configuration editor
2. Replace the content with the following configuration (update your Wi-Fi credentials!):
esphome:

⚠️ While we’ve managed to implement all these features for Mr. Avocado, my recommendation is to comment out (or remove) any parts of the code you’re not planning to use. This will help improve the device’s performance and prevent it from freezing.
6. This code does not include the credentials needed for your device to connect to your Wi-Fi network and your Home Assistant instance. You’ll need to add them manually.
Specifically, I’m referring to the following lines from the code you copied in Step 4.
# Enable Home Assistant API
api:
encryption:
key: "bg6hash6sjdjsdjk02hh0qnQeYVwm123vdfKE8BP5"
ota:
- platform: esphome
password: "asddasda27aab65a48484502b332f"
wifi:
ssid: !secret wifi_ssid
password: !secret wifi_password
# Enable fallback hotspot (captive portal) in case wifi connection fails
ap:
ssid: "Assist Fallback Hotspot"
password: "ZsasdasdHGP2234"
7. What you need to do is to find the corresponding lines in the code (they’re at the top) and add your Wi-Fi and Home Assistant credentials there.
8. Now, click “Save” and then “Install.” Choose “Manual download” and wait for the code to compile.
9. Once the compilation is complete, select the “Modern format” option to download the corresponding .bin file.
10. Connect the M5Stack Dial to your computer using a USB-C data cable via the port on the bottom of the device.
11. Next, go to the ESPHome web page and click “Connect.” In the popup window, select your board and click “Connect.”
12. Then click “Install” again and choose the .bin file you downloaded in step 9. Click “Install” once more to flash the firmware.
13. Return to Home Assistant and go to Settings > Devices & Services.
In most cases, your device should be automatically discovered and appear at the top, waiting for you to click “Configure.”
If not, click “Add Integration,” search for “ESPHome,” and enter your board’s IP address in the Host field. As always, it’s a good idea to assign a static IP to your device in your router settings to avoid connection issues later on.
14. To finish, go to Settings > Devices & Services > ESPHome, click the “Configure” link next to your device, and in the popup window, check the box that says, “Allow this device to make Home Assistant API calls,” then click “Submit.”
This will allow us to control devices directly from the screen.
Alright, you’ve successfully integrated the M5Stack Dial into Home Assistant as Mr. Avocado. Now let’s go over how to take full advantage of its features.
To protect the screen, we’ve added a customizable screensaver function. You can easily tweak it by accessing the entities exposed by the device in Home Assistant. Pay special attention to these three controls.
After a few seconds of inactivity (you can set the duration using the “Screen Saver” slider), the menu automatically hides, showing the clock and date with reduced screen brightness.
Additionally, if you enable “Auto Lock,” the screen will turn off completely a few seconds later (adjustable using the “Auto Lock” slider).
Of course, you can use our default Mr. Avocado background images — or replace them with your own.
Just update the image references in the first few lines of the code to point to your preferred files.
substitutions:
# Device customization
# Personalización del dispositivo
background_image: https://aguacatec.es/wp-content/uploads/2025/02/mravocado_background_white.jpg
background_image_saver: https://aguacatec.es/wp-content/uploads/2025/02/mravocado_bg_off.jpg
background_image_device: https://aguacatec.es/wp-content/uploads/2025/02/mravocado_bg_device.jpeg
You can also customize which devices you want to control and the icons that represent them. Throughout the code, you’ll find examples for controlling different types of entities—lights, climate, vacuum, switches, humidifiers, and more. But if you understand the logic, you can control any Home Assistant device!
The example menu is optimized for 8 devices, but you can add more icons or even paginate the menu. Plus, if you press on any device, you’ll see advanced controls using the rotary encoder.
Since Mr. Avocado has a built-in buzzer, you can use it as an alarm or timer, making it sound whenever you want. Just use the “Alarm” button entity exposed by the device. You can also enable or disable a beep sound when navigating through the menu.
By the way, you can customize the alarm tone, as I explained in this article.
substitutions:
# Sounds
# Sonidos
menu_sound: 'beep:d=64,o=5,b=255:c7'
alarm_sound: 'xmen:d=4,o=6,b=200:16f#5,16g5,16b5,16d,c#,8b5,8f#5,p,16f#5,16g5,16b5,16d,c#,8b5,8g5,p,16f#5,16g5,16b5,16d,c#,8b5,8d,2p,8c#,8b5,2p'
Mr. Avocado also includes an NFC/RFID reader, although it’s not its strongest feature — I find the tag detection to be somewhat imprecise.
Still, if you want to use it, be sure to check out this article where I explain in detail how to create automations for each specific tag.
By the way, if you like it, you can also get our custom Mr. Avocado stand!
Thanks to the threaded mount built into the M5Stack Dial, attaching it is very easy. Just screw the device onto the stand’s base and route the USB-C power cable through the rear opening.
I recommend using a 90º angled USB-C cable to make positioning easier (although you can also rotate the screen to your liking).
Also, keep in mind the case has space at the top and an opening at the bottom—both intentionally designed so you can access the two expansion ports (I2C and GPIO) to add your favorite sensors.
⭐ If you have a 3D printer, you can download this stand I designed from our Patreon profile. If not, you can also purchase it from La R3D and have it shipped to your home!

Launched in October 2023 by M5Stack, the StickC Plus2 has quickly become a popular choice among makers, educators, and embedded system developers. It’s widely used in IoT projects, embedded systems, and cybersecurity applications. Many users even compare it with Flipper Zero as affordable alternatives for their similar roles in wireless testing and cybersecurity tools.
In this article, we’ll walk you through the StickC Plus2’s key features, programming options, and practical project ideas.
The M5StickC Plus2 is a compact, all-in-one ESP32-S3 development board designed for rapid prototyping and embedded applications. It integrates a 1.14” TFT display, IMU, microphone, infrared transmitter, and rechargeable battery — all within an ultra-portable form factor.
With support for Arduino, UIFlow2, and MicroPython, the StickC Plus2 is well-suited for a wide range of applications, from IoT devices and wearable interfaces to educational tools and lightweight cybersecurity projects.
M5StickC Plus2 builds on the StickC Plus with a new ESP32-PICO-V3-02 chip, increased battery capacity, improved Wi-Fi and infrared performance, and an upgraded CH9102 UART for more stable USB communication. However, the original StickC Plus has a built-in battery management IC that Plus2 lacks.
M5StickC Plus2 is a compact ESP32-S3 board ideal for developers looking to build custom IoT or cybersecurity tools. With third-party firmware (Like Bruce), it can emulate some Flipper Zero features like RF, IR, and USB HID.
Flipper Zero, on the other hand, is a ready-made hacking device with built-in wireless protocols, perfect for users who want an all-in-one security testing tool without programming.
Designed for the ESP32 microcontroller platform, Bruce merges Wi-Fi, RF (Radio Frequency), BLE (Bluetooth Low Energy), IR, and USB capabilities into a single, modular offensive toolkit tailored for red team activities and security research.
The easiest way to install Bruce on your M5Stack device is with M5Burner, M5Stack’s official firmware flashing tool.
If you haven’t downloaded it yet, click here to get started.
Open M5Burner > Select STICKC > Scroll down and you’ll see Bruce for StickC plus2 (or simply type “Bruce” into the search bar to locate it quickly.)
Click Download > Connect your device via a USB cable > Click Burn, select the corresponding USB port and default baud rate 1500000 > Hit Start to begin flashing
Note: Bruce is an open-source, community-developed firmware project not officially affiliated with M5Stack. A warning may pop up when you download the firmware.
Once you see the message "Burn successfully, click here to return", click it to finish, and press the reset button on your device once to let it start. Now you can begin exploring its features!
Note: If any issues occur during flashing, you may need to install a USB driver on your computer, or long-press the reset button on the main controller to enter download mode. For details, refer to the documentation page of your specific main controller device.

Today, we’re checking out another great device for running our assistant with excellent performance, and learning how to activate Assist using the M5Stack CoreS3SE.
Index
Well, let's start with the basics. M5Stack is the brand behind well-known devices like the Atom Echo. As I mentioned before, this was the first external device used to interact with Home Assistant. I’m convinced that if you're getting into the world of local assistants, you’re already familiar with it.
But Atom Echo isn’t the only option. M5Stack also makes a variety of ESP-based devices that are easy to integrate with Home Assistant. Think of them like custom ESPHome builds, but without the hassle of soldering, wiring, or configuring components from scratch.
Now that the introduction is done, today I want to introduce you to the M5Stack CoreS3SE, a device that’ll definitely remind you of the ESP32-S3-BOX-3 we looked at recently, as we can also activate Assist with the M5Stack CoreS3SE.
Since the goal of this guide is to activate Assist using the M5Stack CoreS3SE, I’ll go over the differences and similarities I’ve found between the two devices.
Prerequisites
To activate Assist on the M5Stack CoreS3SE, you’ll need:
🥑 If you're setting up Assist, I highly recommend checking out the workshop from the academy to get the most out of it!
Follow these preparation steps to get your M5Stack CoreS3SE up and running:
1. In Home Assistant, go to your ESPHome add-on, click on “New Device”, then “Continue”.
2. Give your device a name (e.g., “Assist”) and click “Next”.
3. For the device type, select “ESP32-S3”. You’ll see a new block for your device appear in the background.
4. Click “Skip”, then click “Edit” on your device’s card. Copy the code that appears and keep it handy — you’ll need part of it later.
5. Head over to the GitHub page linked in the guide, copy the provided code, and replace the original ESPHome code with it.
6. Important: This new code doesn’t include your Wi-Fi or Home Assistant credentials, so you’ll need to manually add them. Specifically, look for the lines from the original code that you copied in step 4 and insert them into the new code.

In this article, we will integrate the M5Stack Air Quality Kit with Home Assistant to monitor air quality.
Index
While air quality may not be a concern for everyone, those of us living in large cities or near industrial areas are increasingly worried about the air we breathe at home. This concern is not unfounded—numerous studies have shown that long-term exposure to pollutants can lead to respiratory diseases such as asthma and bronchitis. Over time, it can also shorten lifespan and increase the risk of chronic illnesses like lung cancer.
From this perspective, home automation can help mitigate these effects by monitoring air quality, sending alerts when pollution levels rise, or even activating ventilation or air purification systems. If you're concerned about overall environmental pollution, you can refer to indexes like the World Air Quality Index.
However, whether you distrust external data (for instance, if monitoring stations are conveniently placed in green zones) or simply want to measure the specific data in your own home, an air quality sensor is essential. When it comes to finding a sensor that is comprehensive, integrable, and reasonably priced, debates always arise.
M5Stack is a well-known brand that offers devices like the M5Stack CoreS3SE and the historically significant Atom Echo. In this case, we’ll integrate the M5Stack Air Quality Kit with Home Assistant. This device is based on the ESP32S3FN8 chip and can measure CO2, VOCs, PM1.0, PM2.5, PM4, and PM10 particles, along with temperature and humidity (though some reviews suggest the accuracy of the latter two may be questionable). It also features an e-ink display and a built-in battery.
By the way, while this article focuses on integrating the M5Stack Air Quality Kit with Home Assistant, you can also use it directly with your mobile device to monitor its readings. The video below explains the setup process.
To integrate the M5Stack Air Quality Kit into Home Assistant, you will need:
🥑 If you’re new to ESPHome, I recommend checking out the Academy workshop to get the most of it!
Follow these steps to integrate the M5Stack Air Quality Kit into Home Assistant:
1. In Home Assistant, go to your ESPHome plugin, click “New Device,” and then click “Continue.”
2. Name your device (e.g., “ Air Quality Kit”) and click “Next.”
3. Select “ESP32-S3” as the device type. You'll notice that a new block has been created for your device in the background.
4. Click “Skip” and click “Edit” on the device block above. Copy the code that appears and save it, as you will need some parts of it later.
5. Copy the following code (which I found on reddit and edited slightly) and replace the above code in ESPHome.

6. Important: This code does not include the credentials for connecting the device to your Wi-Fi and Home Assistant instance, so you will need to enter them manually. Specifically, I am referring to the following lines of code that you copied in step 4.
# Enable Home Assistant API
api:
encryption:
key: "bg6hash6sjdjsdjk02hh0qnQeYVwm123vdfKE8BP5"
ota:
- platform: esphome
password: "asddasda27aab65a48484502b332f"
wifi:
ssid: !secret wifi_ssid
password: !secret wifi_password
# Enable fallback hotspot (captive portal) in case wifi connection fails

7. What you need to do is find the corresponding lines in the code (at the beginning) and add the necessary information.
8. Now, click “Save” and “Install.” Select “Manual download” and wait for the code to compile.
9. When finished, select the “Modern format” option to download the corresponding “.bin” file.
10. Connect the M5Stack Air Quality Kit to your computer using the USB-C data cable via the port on the bottom.
11. Now go to the ESPHome page and click "Connect." In the pop-up window, select your board and click "Connect."
12. Now click on “Install” and select the '.bin' file obtained in step 9. Again, click on “Install”.
13. Go back to Home Assistant and navigate to Settings > Devices & Services. Your device should be discovered and appear at the top, ready for you to click the “Configure” button. If not, click the “Add Integration” button, search for "ESPHome," and enter your board’s IP address in the "Host" field.
If you navigate to Settings > Devices & Services > ESPHome and select the M5Stack Air Quality Kit, you'll find several entities providing information about air quality.
Additionally, the buttons on the device's top-left corner have also been exposed as entities. This means you can create an automation to trigger an action when you press them, such as activating your ventilation system.
To set this up, go to Settings > Automations and Scenes > Create Automation. In the "When" section, add a "State" trigger. In the entity field, select the one corresponding to your device (e.g., 'binary_sensor.airq_button_a'), and in the "To" field, choose "On." Then, simply add the desired actions.

On November 18, 2024, M5Stack opened its doors to individual visitors for the first time. More than 70 visitors from all around the world attended the event, with some showcasing their projects built with M5 products or sharing their stories with M5Stack.
The event began at 3:00 PM, with many visitors checking in and receiving their gifts—custom T-shirts featuring the M5Stack logo. After a group photo, the first agenda kicked off: The Factory and Office Tour.
The visitors were divided into three groups, with introductions provided in Chinese, English, and Japanese. M5Stack operates an all-in-one facility where product design, production, packaging, quality control, marketing, and shipping are seamlessly managed under one place. Visitors could take a close look at the whole flow.
In the show board area, we display all the products we've created so far, including the classic 5x5 stack series—such as M5Basic Core, M5Core2, M5Core3, and Stick series—like the M5StickC, along with the Stamp Series (M5Cardputer, M5StampFly), and the Atom series (M5Atom Echo), among others. M5Stack’s CEO, Jimmy Lai, also explains "What is M5Stack?"
M5Stack is an open-source hardware IoT solution provider, primarily focused on products built around the ESP32. We also offer a range of accessories and our own visual programming platform, UIFlow. The "M" in M5Stack stands for Module, "5" represents the 5x5 cm size, and "Stack" refers to their stackable design.
M5Stack is committed to delivering convenient, stackable and easy-to-use development components and tools, with at least one new product every Friday, we launch over 50 new products every year. We provide not only standard products, also customized products. Our partner includes Amazon, Microsoft, Arduino, SONY, etc.
After the tour, it’s time for the Meetup. This year, we have 9 speakers. Jimmy began by sharing the company’s history, followed by presentations from the speakers. TAKASU Masakazu shared the success stories of M5Stack in Japan, where the Japanese market accounts for 35% of M5Stack’s global sales. Many companies and schools in Japan use M5Stack products, and you can even find books on how to use M5Stack products on Amazon.
Other speakers introduced their innovative projects, including the Creative Dot Matrix Clock, the M5Unified Library, M5Cuffbox, and the Blue Tears Incubator, how to make stack-chan bigger, etc.
It was a truly enjoyable experience to come together with M5Stack fans from all over. We appreciate everyone’s enthusiasm and participation, and we’re already looking forward to welcoming you again next year. See you then!
