I’m working with esphome web for the moment and created a yaml file.
To upload this file o the esp32, I need to convert this yaml to a bin file. How can I do this ?
On esphome dashboard open your device and click Install.
Choose manual download
It will give you factory.bin file
And it takes a while…
Neither do I. But somewhere you need to compile your yaml.
I use esphome standalone installation on my laptop.
I tried the ready made projects (empty esphome device) and flashed the esp32. But how to go further.

I installed esphome on my windows computer following this tutorial.
but I’m blocked because I have on some way convert my yaml file to a bin file.
With esphome I have to install the bin-file, but I only heve the yaml file
After the installation you have to use it. Please read the documentation.
You are using ESPHome-Web, which is different from ESPHome and serves just the purpose of flashing a device.
What documentation ? Is there a step by step tutorial ?
I followed the documentation you mentioned.
All the documentation I found talks about the yaml file, but I cannot find anything how I go from a yaml file to a bin file to upload.
Actually I flashed the 'empty esphome device 'project. I can se the esp32 on my network with his IP-address (192.168.43.94) but I cannot connect to him.
Do a search on Google “esphome how to use” and you will get some advice like youtube videos that explain how to use it, like this one: https://youtu.be/XMpNJgozF-c?si=gGlbn-zOhxEy4ZeS
You need to “build” your yaml through the esphome builder dashboard:
there you can click EDIT and install:
then choose manual download to create the bin file:
Thanks, but this video does not show how to create the bin-file with esphome-web. They do it again with home assistant.
Because I have no homeassistant, I cannot use the esphome builder in HA
You can’t create the bin file using esphome-web. You must use ESPHome that you have installed on windows. Try to type the command esphome on your windows machine.
Here is a youtuber explaining it for windows: https://youtu.be/BX6tDsux_X4?si=qVthkjlyuZwlfZ-2
With this video I move some steps forward but now I’m block with running esphome in terminal with following message :
"Processing ap (board: esp32dev; framework: arduino, espidf; platform: https://github.com/pioarduino/platform-espressif32/releases/download/55.03.37/platform-espressif32.zip)
Git not found in PATH, please install Git.
Git is needed for Platform espressif32 to work."
Do you have an Internet connection from your Windows pc?
No fix ethernet. I work over Wifi with my mobile as hotspot
I think problem is solved. I removed python and esphome and installed an older version of both.
Python 3.13.7
Esphome 25.0.8
Where is the bin-file stored ( directory on the PC) ? I can only see that the file is uploaded to the esp32
something like C:\User/{username}/.esphome/build/{your_device}/.pioenvs/{your_device}/firmware.bin
