it seems a very useful device. it’s easy to use & easy to install . i think it would protect my house from high or low voltage & current. it has also earth leakage protection. it looks good material product. it deliver before the estimate time & safe delivery. thanks for ali Express.

Very fast delivery, good protective packaging, will order again, long CT wires, not tested yet. with din rail adapter

The parcel arrived a little crumpled, but the goods are intact, the packaging and the instruction (in English) are in the photo, the iron is connected for the test, the reading is consistent, the device is not heated, it is possible to set the time, but T. I will not install any built-in batteries for storage and time countdown. There are a lot of functions, as stated, for example, power, current, voltage, hertsy, etc. Are present, the screen readability is excellent… In the end-I am satisfied with the product, I recommend it for purchase, delivery in a couple of weeks.

Device is working fine. But need some improvement in application level.

1. The power Button on the Toya smart app is not clear whether it is button or an icon. It should be popup the message for-confirmation after the click. if you touch accidently on the icon of power the breaker will be off.
2. Metering should have feature to filter and calculate the electricity usage on peak hours and off-peak hour of the month. Different electricity tariff rate enter (peak hour and off-peak hour) should also be available.
By adding above features we can easily calculate the electricity bill of peak-hours and off-peak hours.
3. Energy meter main page on each phase shows combine power directions. It should be show on both directions.
