Fast shipping and quality material, I haven’t been able to test it yet

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.

When installing, you will need a jugby hub. There are three switch modes: Once short, twice short, once long. I struggled a little when I opened the back cover. There are small flaws on both sides of the back cover, but give me some strength there after working with the body. I opened it. The battery must be purchased separately as CR2032. The switch push feeling was crude.

The device is excellent, arrived quickly, I recommend the seller!

Prompt delivery. Goods exactly as shown and work well. Thank you.
