MAKING A WIFI BUTTON: Home Automation Trigger By Using Node-RED

Triggering automations by using wireless nodes around the house is definitely something that will be useful. I decided to create an efficient WiFi switch that could be used as a master power switch for my workspace. In this video, I show you how it was designed and I also talk about the different design considerations that led up to the final design. This can be used as the basis to do even more interesting things.

I've used a Wemos D1 mini for this project along with a simple Arduino sketch. Every time the board powers up, it publishes a message to the MQTT broker that's running on Home Assistant. This is then picked up by Node-RED and it is used to control the lights in the room. I will also be adding a SonOff switch to power down the lab equipment with the press of a single button. In an ideal world, the node can run for 8.65 years from 2x AA batteries. However, I decided to use smaller, 240mAh rechargeable Lithium-Ion batteries which would give me an ideal run time of around 10 months.
