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

Very good product and remarkable value for money. Does over/under current/voltage protection, leakage current protection. Installation very easy, works with SmartLife app.

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.

Net meter proper work

Fine work

Device couldn't connect with Wifi

The bidirectional meter is working as expected. I am able to monitor all the details from my phone easily.The price of the product is also very good, and even lower when compared to directly importing from china.

Installed it about 30 days back. It’s functionally good, so far. I am using Solar off grid power mainly. So , wanted a devise to check and balance my usage at home. Few times when the voltage went above 240 , the power was cut off automatically with a warning message to the app in my phone. I am getting used to it, slowly. When it’s fixed properly, in the initial stage, there is no hassles. I browsed through the website of manufacturer atorch.cn which is in Mandarin. No English version. App has a fine English version, which is helpful. I am not over enthusiastic about the product but being cautious. So far it’s good and handy as well. Will be writing another review after 3 months basing on my usage experience ( before recommending the product to my friends )
