Icasca · Reviewed by Felps · Published 2026-07-28
Based on a review by Felps (accessed 2026-07-28).
Based on this review alone: buy it if you care about stable zigbee connection for reliable performance — just accept requires a neutral wire for installation, which may necessitate an electrician for older homes.
The reviewer concludes that with the Alexa Plus, controlling a smart home using voice commands has become significantly more practical and enjoyable, largely due to its improved ability to understand natural language and differentiate between devices across different rooms, eliminating the confusion experienced with the regular Alexa.
This video details the installation of over 20 Zigbee smart switches from brands like Icasca, Nova Digital, and Zemismart throughout the reviewer's house. It showcases the setup process for various switch types and demonstrates how to integrate and control them using the new "Alexa Plus" with improved AI voice command capabilities.
Installing these smart Zigbee switches is highly recommended for anyone looking to fully automate their home lighting, especially when paired with the new Alexa Plus. The robust Zigbee connection provides stable performance and allows for local automations, even if the internet is down, a significant advantage. While the installation requires careful attention to wiring, particularly the neutral wire, and initial app setup, the enhanced voice control capabilities offered by Alexa Plus make it a worthwhile effort. If you desire advanced, natural language control over your entire home's lighting setup, these switches integrated with Alexa Plus are an excellent choice. However, if you lack neutral wiring or prefer a simpler, less integrated approach, you might need to consider other smart lighting options.

In the gourmet area, the reviewer installs a main six-key Icasca 4x4 switch. He describes it as "very top" and indicates it controls several lights.
hands_on_demopositivet=7:44–8:18
The reviewer demonstrates using a 3D-printed adapter to install a smaller 4x2 switch into a larger 4x4 wall box, showing an innovative solution for aesthetic and functional needs. This allows him to reuse an existing switch.

The reviewer states he installed switches throughout the entire house, including bathrooms (with integrated outlets for hair dryers), guest rooms, and the garage, where they will be useful for scheduling front house lights.
hands_on_demoneutralt=9:18–10:20
The reviewer demonstrates how he organized all the installed Zigbee switches within the SmartLife application and then in the Alexa app. He assigned correct names to each switch, grouped them by room, and configured them as 'lights' to facilitate voice control.

Using an Echo Dot Max in the studio, the reviewer commands, 'Alexa, ligue o abajur.' Alexa Plus successfully turns on the studio's abajur without confusing it with similar devices in other parts of the house.
hands_on_demopositivet=11:21–11:53
In the bedroom, the reviewer issues a multi-part command: 'Alexa, desligue a luz principal, os spots e ligue a luz da cortina.' Alexa Plus executes this complex command correctly, affecting only the bedroom lights.
hands_on_demopositivet=11:57–12:28
In the living room, the reviewer gives a similar complex command: 'Alexa, desligue o lustre, os spots e ligue a luz da cortina, por favor.' Alexa Plus successfully controls the specific lights in that environment, creating a more ambient setting.
hands_on_demopositivet=12:32–13:08
In the guest room/office, the reviewer demonstrates another complex command: 'Alexa, desligue o abajur, a cortina, a luz do banheiro do escritório e também ligue a luz principal e os spots.' Alexa Plus manages to execute all parts of this detailed command successfully.
hands_on_demopositivet=13:17–14:14
The reviewer shows that Alexa Plus can control multiple lights with a single command if they share a common name component, such as 'fachada'. By saying 'Alexa, ligue a fachada,' all lights named 'arandela da fachada' or 'LED da fachada' turn on, including those on the veranda.
The reviewer found that Alexa Plus, with its AI capabilities, greatly enhanced the experience of controlling smart home devices via voice. It effectively eliminates the confusion and errors that the regular Alexa often had, allowing for more natural and complex commands without the system getting mixed up, even with numerous devices in a home.
The reviewer chose Zigbee smart switches because they offer a more stable connection compared to other protocols. A key benefit is the ability to perform local automations, such as virtual parallels between switches, without needing an active internet connection. This ensures continued functionality even during internet outages.
The reviewer found a wide range of smart switch models suitable for various needs across the house. These include switches with two, three, four, or six keys, catering to different lighting setups. Furthermore, models with integrated 20-amp power outlets are available, ideal for areas like bathrooms where high-power appliances like hair dryers might be used. The reviewer also noted a consistent design across these different types.
The reviewer mentioned that the specific Zigbee switches he installed require a neutral wire. He had an electrician pre-install neutral wires to all junction boxes, which 'facilitated the installation a lot.' This suggests that while installation might not be overly complex, having the correct wiring (specifically the neutral wire) is crucial and might require professional assistance if not already present.
The reviewer recommends organizing all smart switches by assigning precise names for each, grouping them within their respective rooms in the Alexa app, and importantly, changing their device type to 'light.' This meticulous organization helps Alexa Plus identify which device to control when a command is given, even for devices with similar names in different areas of the house, preventing confusion.
The reviewer demonstrated that Alexa Plus can successfully process and execute complex voice commands that involve multiple actions and devices within a single command. For instance, he could tell Alexa to "turn off the main light, the spots, and turn on the curtain light" in a specific room, and Alexa Plus would perform all actions correctly without confusion.
The reviewer explicitly demonstrated that Alexa Plus does not get confused between similar devices located in different rooms. For example, when he asked Alexa in the studio to turn on the 'abajur,' it knew to activate the studio's abajur and not one in another part of the house. This contextual awareness prevents misinterpretations, even with identical device names.
