The meter is very easy to install, although it will be nice to include a pair of wire for the voltage sensing. The wire from the current sensor is long enough so I just cut a piece of it for the voltage sensing. The app is compatible for smart life, which is easy to use and nice to be integrated with my other smart devices.

Easy to use, can set protect devices, electrical appliances, various current values can be turned on and off via mobile phone.

Fast Delivery (9 days before Kiev).
The device works fine, but it seems to me that the power readings are overstated (there is no way to check yet). I use homeassistant + zigbee2mqtt. There were minor problems when connecting to the Gateway.
As I understand it, there is one small nuance that has not been written anywhere: the device independently tries to look for the Gateway only after turning on the power, and in a very limited period of time (30-60 seconds). If the gateway is not found during this time, then the device goes into a kind of “passive pairing mode”, in which you need to connect to it through the smart life application. While the LED indication does not change in any way: the LED flashes red.
Resetting the device with the “reset” button does not help, which is not very convenient, since the only way to make it look for the ZigBee network again is to turn off and turn on the power.

Excellent start, you will have to see the duration
