I ordered it for the second time. I installed it on the gas boiler first, it works perfectly. The product quality is good.

I received this Zigbee Repeater just a couple of days after I ordered. Delivery was really quickly. The product was packed properly.
I put the repeater in a USB outlet and immediately my Zigbee controller noticed the new repeater. I just had to accept the message and that’s it. Never installed a Zigbee device so quickly.
The transmit distance of this Zigbee Repeater is very good.
My Zigbee controller is on the frontside of our house and before I had problems getting Zigbee zignal at the backside of our house (distance about 20 meters).
Only with 2 Zigbee smart sockets in between I had good Zigbee signal at the back of our house.

Now, with this Zigbee Repeater I have both in front and back of our house good, stable Zigbee signal.
I even have Zigbee signal in our freestanding garage. Distance between garage and backside of house about 15 meter.
So I’m very happy with this Zigbee repeater. I sure can recommend it.

I recommend the seller very serious

manual is not good, bad translation?
I’m not familiar with Tuya.
with the QR code, I was able to install the app. It’s NOT a Tuya app, but does work nicely.
“Smart Life – Smart Living” (Android)
from “Volcano Technology Limited”.

Adding the device to wifi did not work with the wizard.
(bluetooth and location turned on)
I had to manually go to Energy-wifi smart meter.
then “search”, and now the device was found.

to my surprise (according to the bad experience until now), the app works very nice.
I can see much!

only one minor bug: on the meter, I filled in OVP: 250,0V
strangely, the app saw that as 249,9V.
Other way around does work.

the meter even has a remote on/off switch
