Hello,
Thank you for your feedback and assistance. However, as I am stubborn and resourceful, I have researched how to use my ESP32-H2 and found and programmed a code that allows me to use an ESP32-H2 with a relay connected to light bulbs using Home Assistant. To better do all this, I created a tutorial, but without telling you, I am stuck at a step which is the compilation of the code.
The error I have:1/1] idf (5.3.0)
CMake Error at /Users/name/esp2/v5.3/esp-idf/tools/cmake/build.cmake:268 (message):

I have tried several changes without result. If you have any ideas, I’m open to them.Following this, here’s my tutorial to perhaps start something new on the ESP32-H2To install the ESP-IDF (Espressif IoT Development Framework) in Visual Studio Code (VS Code) on a Mac, here are the steps to follow:Prerequisites on macOS:
- Homebrew:
You need to install Homebrew, a package manager.
Run this command in your terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
- Python 3.x:
You need to verify that Python 3 is installed:
python3 --version
If not installed, move on to the next step.
Step 1: Install ESP-IDF dependencies via HomebrewIn a terminal, run the following commands to install the cmake, ninja, and python3 dependencies:
brew install cmake ninja python3 gitStep 2: Download ESP-IDF
- You need to install the ESP-IDF repository from GitHub via the terminal:
mkdir esp32
git clone --recursive https://github.com/espressif/esp-idf.gitthencd esp-idf
- Install the necessary tools for ESP-IDF:
./install.sh esp32-h2
Replace esp32-h2 with esp32s2, or esp32c3 depending on the esp32.
Step 3: Configure ESP-IDF
Configure the environment by running the following command:
. $HOME/esp/esp-idf/export.sh
This will set up the environment variables for ESP-IDF.
Step 4: Install Visual Studio Code
If you don’t have Visual Studio Code installed yet, download and install it.
Step 5: Then install the ESP-IDF extension for Visual Studio Code
- Launch Visual Studio Code and open the VS Code Marketplace.
- Search for Espressif-IDF in the search bar.
- Install the official Espressif-IDF extension.
Step 6: Configure the ESP-IDF extension in VS Code
- Once the extension is installed, open the Command Palette in Visual Studio Code.
- Type and select ESP-IDF: Configure ESP-IDF extension.
- The extension will guide you to:
o Configure the path to your ESP-IDF (the directory where you cloned esp-idf).
o Install Python and associated tools (if not already done).
o Configure the environment for the extension to work correctly.
Step 7: Verify the configuration
Open the integrated terminal in Visual Studio Code and type the following command to verify that the environment is properly configured:
idf.py --version
You should see the installed version of ESP-IDF.
Step 8: Create a new ESP-IDF project
- Open the Command Palette.
- Type ESP-IDF: Create project to create a new project.
- Choose a Template, select the folder where you want to store your project, and follow the steps.
Step 9: Compile and upload the project
- To compile the project, use the command:
idf.py build
- To upload the firmware to your ESP32, use:
idf.py flash
With these steps, you should be ready to use ESP-IDF with Visual Studio Code on a Mac.
To control relays with an ESP32-H2 via the Zigbee network and interact with Home Assistant.
Here are the steps to follow:
Step 1: Create a directory structure

├── main
│ ├── CMakeLists.txt
│ ├── main.c
│ └── relay_control.h
├── build/
├── sdkconfig
└── CMakeLists.txtFiles to create:
-
main.c:

-

-

I’ll explain the Code:
-
GPIO Configuration: Each relay is connected to a GPIO, configured as output, and we initialize them all to OFF state at startup.
-
Relay Control: The control_relay function allows activating or deactivating a specific relay based on the index and the received command (ON/OFF).
-
Zigbee Callback: The zigbee_on/off_callback receives Zigbee commands from Home Assistant via the Zigbee on/off cluster. The relay is activated or deactivated based on the received command.
-
Zigbee Init: The zigbee_init function initializes the Zigbee stack and registers an endpoint for on/off type messages. This allows Home Assistant to detect the device as an on/off switch and send it commands.
Step 3: Home Assistant Configuration
-
Zigbee Configuration: Make sure your ESP32-H2 is properly configured to work with a Zigbee dongle compatible with Home Assistant.
-
Automatic Detection: Once connected to the Zigbee network, the controller will appear in Home Assistant as a Zigbee device. You can then define entities for each relay and control them via automations or via the user interface.
Step 4: Compilation and Flashing
- Compilation: Compile and flash the code on the ESP32-H2 using the following commands:
Compile the code:
idf.py build
Then flash, if the compilation goes well, move on to the next step:
idf.py flash
Then finish and test.
