Using the PlatformIO IDE

• Download Git (install using the default settings)
• Download and install Visual Studio Code (VSC)
• Restart the PC (if using Windows) to apply the new PATH settings. It should now detect Git
• Install the VSC extension "PlatformIO IDE"
• Git clone this repo with "git clone" from the command palette and using the URL https://github.com/proddy/EMS-ESP.git
• Install NodeJS from here.
• Test if Node is installed correctly by node --version (both v10 and v12 are ok)
• Install the modules in the tools/webfilesbuilder folder with:

cd tools/webfilesbuilder
npm ci

• Check you can build the web files by typing node node_modules/gulp/bin/gulp.js from the webfilesbuilder folder.
• Finally use the build targets in PlatformIO's to build & upload.

If you seeing fatal errors in the npm install and came from an earlier build then you'll may need to refresh the library, like

1. Remove the local node_modules
2. Clean npm cache by npm cache verify
3. Update the global npm by sudo npm ci -g npm
4. Reinstall the local node_modules by npm ci

• Edit ~/.profile and add: export PATH=$PATH:~/.platformio/penv/bin to the end, then exit, and start a new shell
• Update platformio and its libraries

platformio platform update
platformio lib update

• Grab the EMS-ESP source code:

git clone https://github.com/proddy/EMS-ESP.git
