Automate Your Grow with Home Assistant #6: Automating Humidity with Node Red & Dashboard Sliders
HTML-код
- Опубликовано: 11 сен 2024
- We're delving into Node Red for the first time to control our humidity. We'll set up a humidity target and tolerance slider in our Home Assistant Dashboard and configure a Node Red flow to turn a humidifier on and off based on our settings. This flow can be applied to many other tasks!
