In this resource guide I list the most popular smart home light, 3-way and dimmer switches that work with Amazon Alexa and / or Google Assistant.
Disclaimer: These products require the ability to install and/or replace high voltage electrical devices in your home and/or business. Misuse could lead to personal injury or property damage. Do not proceed if you don't feel comfortable with that. If in doubt, consult with a professional electrician. The author takes no responsibility for the proper or improper use of the items and techniques listed below.
I never assume that the circuit breaker to an electrical wire has been turned off or labeled properly. I always use a non-contact voltage tester to double check all wires before proceeding. I strongly suggest that you do the same.
- Klein Tools NCVT-3 Non-Contact Voltage Tester with Flashlight - the builtin flashlight makes it eaiser to see inside junction boxes.
For some of the Belkin devices, enable the WeMo Skill in the Alexa app.
- Wemo Smart Light Switch 2nd Gen - Replaces your light switch. Control your lights from the WeMo switch on the wall, the WeMo app, Alexa or Google Assistant.
3-Way Light Switch
- Wemo Wi-Fi Light Switch, 3-Way - Control Lighting from Anywhere, Easy in-Wall Installation, Works with Alexa, Google Assistant and Apple HomeKit (WLS0403) - for controlling 3-way light switches. For example when you have a switch at the top and bottom of the stairs that controls one light. Note that for each 3-way circuit you only need to replace one of the switches with this switch.
Light Dimmer Switch
You have to be careful with when installing any type of dimmer switch. Read all manuals and only use them with simple lights. I don't believe they are meant to control any other electrical devices. For example, I would NOT use them to control the speed of a ceiling fan.
- Wemo Dimmer WiFi Light Switch, Works with Alexa, the Google Assistant and Apple HomeKit (F7C059) - From the product description: "NOTE: works with any one-way connection light switch (not compatible with 3-way) and requires a neutral wire NOTE: Refer the User Manual before use which is highly recommended"
