|
| Node-RED | | # Inštalácia: https://nodered.org/docs/getting-started/windows |
| | #* Online Node-RED environment FRED: https://fred.sensetecnic.com/ |
| | # START http://localhost:1880/ |
| | #* Start Dashboard http://localhost:1880/ui |
| | # Základy |
| | #* Node-RED Guide http://noderedguide.com |
| | #* Cookbook: https://cookbook.nodered.org/basic/map-between-different-number-ranges |
| | # Knižnice: obvykle radia cez npm (node package manager), ale mne to velmi neslo, preto odporucam postup priamo z Node-RED menu: Settings -> Palette -> Install |
| | # Ukladanie: vytvorené flows sa nikam extra neukladajú, ale ak by to náhodou spadlo, prídete o ne. Preto odporúčam cez Menu -> Export uložiť to čo potrebujete |
| | # Koniec: Ctrl+C |
