With the Echo Dot (3rd Gen) ($20, originally $40), you can control your compatible smart home gadgets and appliances. If you have Ring, you can simply say "Alexa, turn on my porch light," "Alexa, answer the front door", or "Alexa, arm Ring." Control your Philips Hue lights with commands like "Alexa, turn on Living Room lights" or "Alexa, set the Kitchen light to Green." If you have a Shark or iRobot cleaning devices, you can control and schedule them via Alexa with commands like "Alexa, tell Shark to pause cleaning." or "Alexa, ask Roomba to start vacuuming."
