For a month now, it has been working perfectly for both kWh and voltage limits. The mobile app and Wi-Fi communication are very good. You can see everything from your mobile phone.

Positives
- Easy to connect
- Displays data correctly, same as the central meter
Negatives
- Disconnects suddenly from wifi, and after reconnecting it does not show the total consumption from the last time it disconnected instead of each day.
- You cannot export the data
- Does not connect to Home Assistant
- Expensive for what it offers

Only as a reliable brand, but otherwise if it had covered the negatives beyond the price it would be a very excellent product

The instructions are very good at the beginning. You connect your phone to the local WiFi. It forces you to connect the phone to see the location, otherwise it won't proceed !!. You activate the bluetooth on your phone and the meter, and download the application from the website or scan the QR. The instructions guide you to connect the meter to the local WiFi. Immediately on your phone, you see the meter's data !!!! Everything went perfectly up to this point !!!
However, if you try to close the meter from the application, then the meter does not open again !!!!
There is no button (reset) to make it work again !!!!
(In this case, we have a house where we suspect electricity theft and we want to remotely turn off the power)
Edit.
To make it work again, I did the following: I removed the meter from the panel, I gave direct power to the house from the DEI clock, (because even if I brought the router close to the panel, there was no way to bring the optical fiber!) I connected the meter with a cable to a socket with power and from there I opened the application again to find a network and be able to operate !!!!
Conclusion:
This particular meter is only for monitoring and measuring consumption on certain devices and not the entire house.
I still can't understand the following:
a) Why does it insist on activating the device's location!
b) Why doesn't the application activate the meter via bluetooth!
c) Who came up with the idea that I should have the house router connected before the meter! (So the router must be connected to a separate socket before the power enters the house !!!)
Edit 14/06/24
So I've been using it for almost a month now and I can say it's excellent. (indeed there was electricity theft) (I raised the stars to 5)
I check it 3-4 times a day.
The application from the phone opens very quickly and I see in real time, what the house is consuming at that moment, how much it has burned each day (it keeps a history) and how much the total kilowatt hours are so far.
