🤖 What Is Alexa Smart Home Automation?

Alexa smart home automation uses Amazon’s voice assistant — Alexa — to control and automate devices in your home using voice commands, routines, schedules, and smartphone control. Alexa acts as the central hub that connects all compatible smart devices, allowing them to communicate and work together.

You can automate routines like:

• Turning off all lights and locking doors when you say “Good night.”
• Starting your coffee maker and adjusting the thermostat every morning at 7 AM.
• Activating security cameras and motion detectors when you leave the house.

It’s all about making your home work for you — hands-free.
