Software on the Raspberry Pi:

  • Mosquitto – a MQTT-Broker, essential for sharing data between sensors and NodeRED (
  • PiVPN – simple to set up VPN (

Software for developers:

  • VSCodium – texteditor or IDE
  • PlatformIO – for developing firmware for ESP8266, ESP32 and Arduino
  • Arduino IDE – still using it, but not as often as PlatformIO
  • Firefox – yes! NodeRED and Grafana are running in your browser, so please use Firefox. Chrome is betrayal!
