I created this application to monitor my speed (download and upload). This app is running on my Raspberry Pi and is sending the values to my own blynk server.
Install your own blynk server using my docker image
// install node dependencies
yarn
// create .env file and add your server + token
cp .env.example .env
node index.js
pm2 start pm2.json
