title: Node-RED description: Point ‘n’ Click workflow automation parent: smarthome position: 300 date: 2021-11-01
update: 2022-05-21
Node-RED is a great tool for visually creating workflows based on events. I use it in conjunction with my ESP-Env sensor and actor hardware and MQTT to automate my smart home.
I plan to extend these workflows as required when I add new hardware to my network.
Here is a simple setup that automatically switches lights in my bathroom according to the sun position, using node-red-contrib-sunevents.
The fan in my window-less bathroom is kept on all the time for now. In the future I want to add movement sensors to the bathroom and integrate them into this logic, as well as the temperature / humidity sensors I already have in there. All these devices run my ESP-Env firmware.
And here are the flows for importing in Node-RED. Copy to clipboard
