2. The Senses: Smart Sensors

   Sensors are the eyes and ears of your smart home, detecting changes in your environment and triggering actions.

   • Motion Sensors: Detect movement to turn on lights, trigger security alerts, or adjust thermostat settings.
   • Door/Window Sensors: Alert you when doors or windows are opened or closed, crucial for security and energy efficiency.
   • Temperature and Humidity Sensors: Monitor your home’s climate to optimize comfort and prevent issues like mold.
   • Leak Sensors: Detect water leaks, saving you from costly water damage.
   • Smoke and Carbon Monoxide Detectors: Integrate these with your smart home for enhanced safety alerts sent directly to your phone.

3. The Actions: Smart Devices

   These are the devices that perform tasks based on commands from your hub or sensor triggers.

   • Smart Lighting: Replace your existing bulbs with smart bulbs or switches for app-controlled dimming, color changes, scheduling, and automation. Brands like Philips Hue, Wyze, and Kasa offer excellent DIY-friendly options.
   • Smart Plugs: Transform any "dumb" appliance into a smart one. Control lamps, fans, coffee makers, and more remotely.
   • Smart Thermostats: Learn your habits and adjust your home’s temperature to save energy and maximize comfort. Nest, Ecobee, and Honeywell are popular choices.
   • Smart Locks: Enhance your home security with keyless entry, remote access control, and activity logs. August and Schlage offer reliable DIY installations.
   • Smart Cameras and Doorbells: Monitor your home remotely, receive alerts for visitors, and enhance your security. Ring, Arlo, and Eufy are well-regarded brands.
