The device is practical and easy to program and operate, but the Internet must be available at home up to the device as well as the Internet mobile network

good seller

Zigbee signal converter received in one week in grouped order. Seems to work properly and installed in seconds under Smartlife with my Zigbee hub. Alexa and Google skills are automatically installed.
No problem for the moment with my Zigbee network capable of transmitting the signal of a sensor fixed in a Letter box located plus 30 meters at the entrance of the property.

I buy 8 units but i only recived 7 units

Faced difficulty to detect the device but after hard power reset it was detected on Zigbee network. Measurement seems ok and accurate, but phase A was giving wrong readings (30,000 watts!) despite installing the clamp in the correct direction same as B and C. After flipping, it seems the reading is corrected, maybe a factory fault in the direction arrow. Store was not helpful in troubleshooting but advised me to return and refund. I refused due to installation cost and effort but ended up diagnosing and fixing the issue. All in all, happy with it.
