XPR3SS AT4PW 100A Single Phase Smart Life Tuya WIFI Din Rail Smart Switch Remote Control AC 220V 110V Digital Power Energy Volt Amp Kwh Frequency Factor Meter

This product is simply Superb. We are observing the energy consumption of our Apartment with out any effort through this WiFi energy meter. Earlier we are carrying a clamp Meter for every electrical problem. Now this meter made it simple. It has many other important features like over voltage, under voltage, over current. We can switch on/off remotely through Wifi also. But this is small to carry 80 Amps load. Now we are using for 20 Amps load. It's working very good.

I recently purchased XPR3SS 80Amp KWS-306WF meter, got it installed in November 2025. So far, it is looking good; it is connected to my WiFi to control my 3 phase steam unit. I can track energy consumption and operate connected devices remotely. It's ideal for people who want to control the electricity consumption of electric products, especially those who can't be physically present. Built quality is good. I found one error, that the volt meter reading of this product has error as it shows higher voltage by 5-6 volts per phase… i checked it with my own multi meter. But i can live with it and do settings accordingly. I feel that they should give a better manual on how to get started with wifi, as there is no mention of usage with the Smart Life app and how to configure it. For beginners, it will become difficult to get started. A tutorial video will definitely help.

This product is multifunctional, combining several features into a single device. It serves as an energy meter while also offering over/under voltage protection, overcurrent protection, and leakage current protection—functions typically handled by separate devices like RCCBs. Essentially, it consolidates multiple devices into one, which is quite convenient. So far, the smart meter has performed well, and I’m satisfied with its functionality. I’ve tested its voltage, current, and leakage current protection features, and they work as advertised. The auto-reconnect feature is particularly useful, as it automatically restores the connection once the fault condition is resolved. Wi-Fi connectivity has been reliable, with only one instance where the device went offline. Restarting the main power supply resolved the issue quickly. The device’s display provides most of the essential information, although it doesn’t show real-time power usage (kW). To view this, you either need to calculate it manually using voltage and current readings or check the Smart Life app. The app offers useful statistics such as daily, monthly, and yearly kWh consumption graphs. However, it would be even better if it also tracked and displayed trends for other parameters like power, voltage, current, and leakage current. Device settings can be configured either directly on the unit or through the app, which adds flexibility. That said, the app’s font and color scheme—especially on the energy statistics screen—could be improved for better readability. Hopefully, future updates will include customization options for the theme. The leakage current protection feature is excellent and can be disabled if needed. During testing, I noticed that while voltage and current protection alarms were logged correctly in the app, the leakage current alarm wasn’t recorded—likely a bug that needs addressing. One caution regarding the “Remote ON/OFF” feature: while you can turn the device off remotely via the app, turning it back on isn’t possible if your Wi-Fi router is powered by the same supply. In such cases, manual intervention is required to restore power. Overall, it’s a solid product and I’ve had no issues so far. I hope it continues to perform reliably over time. For configuration-related queries, I contacted the seller and was impressed by their prompt and helpful response. They even provided a video demonstration, which made the setup process much easier.

I have ordered 3 times but seller sended me Used and defective product every time never trust such type of sellers. Amazon should remove this type of seller from there website

"I’ve been using this voltage protector for a few weeks, and it performs exactly as promised. It reacts quickly to voltage fluctuations and keeps my appliances safe. Build quality is solid, installation was easy, and it gives clear indicator lights. Definitely worth the money!"

Best my product and best and delivery thank you my jaan Amazon

It is good and gives all the readings fine.

Here is what this multifunction meter AT4PW by Atorch has. Pros: -- BIG bright display with display rotation feature -- 100A Relay (Ofcourse not tested with this hige load). But terminal blocks and relay operation appears excellent. -- Over Voltage Protections - Yes -- Under Voltage Function - Yes -- Over Power Protection (Cut outout If wattage is high) - Yes -- WIFI and Mobile Operation - Yes (SmartLife OR TUYA) -- Temperature Function - Yes --- Can be automated to switch off if temperature is above threshold ... -- Scheduler / Timer for auto switch on switch off - Yes (With Smartlife App or TUYA app) -- Good customer support by whatsapp. Cons: -- AQI, PM, Humidity sensor - Does Not exist evnthough it is advertised as existing. One reason I chose to give a 4 star instead of 5. An honest listing always helps. -- Leakage Current function - Does not exist. This parameter protects the home from an accidental electric shock. A must have feature. In fact i kept on searching for this and have to return many products falsely claiming this feature. This one does not claim to have. So no misrepresentation. However it would have been an excellent all in one with this feature. Hope supplier will see to it. This review is very similar to near similar small form factor ATORCH other model with smaller display. Overall an excellent buy and good customer support. However i could not keep the product since my requirement was not fullfilled. Bought that for ore sensors being advertised than it's smaller cousin model. Since i already own the smaller model and it is same....no point keeping it.
