If you are using a not-very-powerful Home Assistant Green, your computer is weak, or you work on Windows where there is no native ESPHome Dashboard app, you can use the Play with Docker sandbox website as a temporary solution.
The site lets you run almost any container for four hours, which is enough time to write and compile your firmware. The firmware builds quickly and without any trouble.
Getting started with Play with Docker
begins with signing in to the service and starting a new session that lasts four hours.
After that, you can install ESPHome in the terminal by pulling the image with command
docker pull ghcr.io/esphome/esphome
You can paste text into the console using Shift + Ctrl + V. Then you launch the dashboard with the command
docker run --rm --net=host -v “${PWD}”:/config -it Package esphome · GitHub.
Once the container is running, you open the dashboard by pressing open port and entering port 6052.
After that, you will see the ESPHome graphical dashboard, similar to the one used in Home Assistant
