## Description

smarteefi Wifi 2 Node Toggle 2 Way Smart Switch (PRO-SERIES), Retrofit, Works With Existing Switches, No Hub Required, Compatible With Alexa And Google Home (PRO-SERIES, 2 Node), 230 Volts : desertcart.in: Home Improvement

Review: Excellent WiFi Switch Controller – Seamless Smart Home Upgrade - I’ve been using this WiFi switch controller for a couple of days now, and it’s transformed my home automation setup. It’s incredibly reliable for controlling everyday appliances remotely via the app, and the standout feature is its flawless integration with Alexa. I paired it effortlessly with my Echo devices to voice-control my jhoomer (ceiling fan), lights, and other switch-based appliances —no hubs required! What I love most is the true two-way sync: if I turn off the switch manually or through the app, Alexa instantly reflects the “off” status, and vice versa. No more confusion about the actual state of your devices. Setup was a breeze—took under 5 minutes on my 2.4GHz WiFi network. But the real hero was the support team: I called them before installation with a quick query, and they picked up on the first ring, walking me through pairing step-by-step without any hassle. Pros: • Alexa and google compatibility (works both ways for status updates). • Easy app control for scheduling, timers, and grouping multiple devices. • No WiFi dropouts even in larger rooms.
Review: EXCEEDS EXPECTATIONS! - This Device bridges the gap between traditional electrical systems and modern smart home technology by fitting inside your existing switchboard. It offers the convenience of app and voice control and does not need complete overhaul of your home's wiring or aesthetics... Seamless Integration: The main advantage is its compatibility with existing "dumb" switches, allowing you to maintain your home's current decor. Voice Assistant Compatibility: Smooth operation and easy integration with major platforms like desertcart Alexa and Google Home, making voice commands highly responsive. Remote Control: The ability to have control remotely via a smartphone app. I am glad it does not use the generic smart life app and has its own app. Offline Functionality: Working smoothly in both online and offline modes, ensuring basic functionality even without an internet connection. Compact Size: Compact form factor that can be easily accommodated inside standard electrical boxes Automation Schedules: childs play to set tasks and assign on off timing for each switch including timers set once and forget Extra functionality includes you getting notifications on the app if the switch has been turned on or of manually and if either through voice assistant, so it acts as a security device as well. My personal take is, go for it blindly !

### ⭐⭐⭐⭐⭐ Excellent Smart Switch
*by J***M on 1 November 2025*

I’ve been using the Smarteefi 6 Node Smart Switch (PRO-IO-Series) for a few weeks now, and I’m really impressed with its performance and build quality. The installation was smooth — it’s a true retrofit design, so I didn’t have to make any wiring changes. The best part is that it supports both inverter and mains together, which is a big plus during power cuts. Connectivity is stable, and the response time through the Smarteefi app, Alexa, and Google Home is almost instant. Overall, a reliable, feature-rich smart switch made in India with excellent after-sales support. Highly recommended for anyone upgrading to a smart home setup!
