To provide a comprehensive overview of smart home features controllable by Alexa, I'll draw from the detailed sources gathered. Here is an in-depth explanation of what Alexa can control in a smart home, how it interacts with those devices, the ecosystem it supports, and practical examples of use:

Overview of Alexa Smart Home Control
Alexa, Amazon's voice assistant, serves as a powerful platform to control a wide range of smart home devices using voice commands or the Alexa app. Through its dedicated Smart Home Skill API, Alexa can connect to cloud-connected smart devices, allowing users to manage them seamlessly by voice or remotely from mobile devices. This includes controlling lights, thermostats, cameras, plugs, door locks, entertainment systems, and various other smart appliances.
Alexa supports both synchronous and asynchronous control, meaning it can send commands to devices instantly or manage them with some latency depending on device cloud architecture. It also supports device state reporting, so users can ask Alexa about the current status of a device, such as whether a light is on or the temperature of the home.

Categories of Smart Home Devices Alexa Controls
Smart Lighting
One of the most popular smart home features Alexa controls is lighting. Users can turn lights on or off, dim them, change colors if supported, and set lighting scenes. Alexa can group multiple lights for simultaneous control, such as all lights in a room or specific zones. For instance, commands like "Alexa, turn the living room lights to 50%" or "Alexa, change the kids' room lights to blue" streamline lighting management.
Thermostats
Alexa can control smart thermostats, adjusting temperature settings with voice commands or routines. This gives users the convenience of adjusting home heating or cooling levels without manual interaction with the thermostat, improving comfort and energy efficiency. Example commands would be "Alexa, set the thermostat to 72 degrees" or "Alexa, make it warmer in here".
Security Cameras and Video Doorbells
Alexa integrates with smart cameras and video doorbells, providing live views and motion alerts on Echo Show and Fire TV devices. For example, Alexa can announce when someone is at the door or when motion is detected, and users can view the camera feed by voice, such as "Alexa, show me the front door camera".
Smart Plugs and Outlets
Smart plugs allow users to control ordinary appliances by voice or app through Alexa. By plugging devices into smart outlets that are Alexa-enabled, users can turn on/off lamps, fans, coffee makers, and more. Alexa can also automate these plugs through routines for scheduled or triggered control.
Door Locks and Garage Doors
Smart locks connected to Alexa enable voice or app commands for locking and unlocking doors, bolstering home security. Alexa can notify users if a door is left unlocked and can also help lock doors remotely. Similarly, some garage door openers compatible with Alexa allow opening or closing with voice commands, increasing convenience.
Entertainment Systems
Alexa controls smart TVs, sound systems, and media streaming devices. Users can turn TVs on or off, adjust volume, change channels, play specific shows or movies with commands like "Alexa, play [show] on Fire TV," and manage multi-room playback playback.
Sensors and Automation Devices
Alexa supports sensors, such as motion sensors, light sensors, and environmental monitors that enable automation. For example, triggering lights or alarms based on motion or environmental changes can be set up through Alexa routines.

Alexa Routines and Automation
Alexa Routines allow users to automate multiple smart home actions with a single voice command or trigger. For example, saying "Alexa, good morning" might turn on lights, adjust the thermostat, read news briefings, and start a coffee maker simultaneously. Routines can be customized for time-based schedules, sensor triggers, or smart device states, making home automation highly adaptable.
Alexa also offers Hunches, a feature where Alexa learns usage patterns and can suggest actions, such as reminding if a door was left unlocked or lights remaining on, enhancing home security and energy efficiency.

Voice Interaction and App Control
Alexa's control extends beyond voice to the Alexa app, which users can use to view device status, issue commands, create groups, and manage routines. Devices discovered by Alexa can be managed individually or in groups, allowing for flexible control. The voice interaction uses a pre-built voice model tuned for smart home commands, ensuring accurate recognition and response to user requests.

Integration with Third-Party Smart Home Devices and Skills
Alexa supports a vast ecosystem of third-party smart home devices via Skills available in the Alexa Skills Store. These skills enable Alexa to interact with various smart systems beyond the default Alexa-compatible devices, such as advanced security systems, specialty lighting, health monitoring devices, and even entertainment and lifestyle apps like exercise guides and wine pairing suggestions.
Users can enable these skills in the Alexa app and link accounts to add more capabilities, further expanding Alexa's smart home control functionality.

Practical Use Cases
- Morning Routine: "Alexa, good morning" turns on bedroom lights, reads weather, and starts the coffee machine.
- Security: Receive announcements of visitors from video doorbells, check cameras on Echo Show, lock doors remotely.
- Energy Saving: Use Alexa to ensure all lights and devices are off before leaving, with reminders about unlocked doors or open windows.
- Entertainment: Voice control TV, speakers, and multi-room playback from Alexa devices.
- Climate Control: Change thermostat settings for comfort or energy-saving modes.
- Lighting Scenes: Set movie night scenes by dimming lights and turning on TVs with one command.
