NS51 (5 Node Pro Series)

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.

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!

Highly recommended for reliability, compatibility, and performance.

Fantastic product. Feature rich. Can do pretty whatever you can think of. For geyser, AC etc, countdown timer is very useful. So is loop timer and scheduler. Using it to automatically switch on / off geyser on the morning so that we have hot water when we wake up. That's gives me extra time to sleep. I struggled a bit with setup as I was trying to configure it by giving just phase and neutral without completing the actual wiring. That doesn't work. To get into setup mode, you need to do the full wiring. Once I figured that out, setup was easy. I hope it is reliable and works for a long time.

Product has good build quality compared to all the available competition in the market for smart switches. Only real competition against Smarteefi is sonoff switches which comes with better build quality. Sonoff switches has native support for home assistant so they are one step better for automation also. On the feature side, Smarteefi checks most of the expected features, you can add schedules, works offline after one time setup, good build quality so that its much safer than other Indian made smart devices when it comes to fire hazard and electric shocks and short circuits. Smartphone notification issue: They have this constant and non configurable notification whenever the switch is turned on or off. This is a novelty for first day and quickly becomes an annoyance. Imagine you get notification on your phone whenever someone in your house turns on/off a bathroom heater or an attic light or when gate light is turned off in the morning by scheduler. It gets irritating very quickly. App do not have native support for turning off notifications or choosing whether you want only specific notifications. You need to disable notification permission for the app in the android's app settings which disables entire notifications altogether. There is no separate notification channel for automated and manual events. No smart home integrations: You cannot directly integrate the switch in home assistant for automating based on other sensors like presence sensor or weather forecast. it supports smart assistants like google assistant and alexa, but they are very novel and limited in what can be done. A proper home automation integration would have made this product at par with sonoff products.
