Excellent product working perfectly in ZigBee 2 MQTT recognizes them with all their functions, just that when pairing hold the button for about 5 seconds more as they enter pairing mode to be recognized in all their functions. In case it shows an error when trying to modify a parameter, they need to be paired again from there they don't give errors anymore. The overcurrent and undervoltage protection function works well but

Very pleased with this order from start to finish. The item arrived well packaged and in excellent condition, exactly as described. Delivery was faster than expected, and everything worked right out of the box without any issues. The quality is solid and matches the photos shown by the seller. I’ve been testing it for a little while now and it performs reliably, so no complaints at all. Communication from the seller was also good β€” i received updates and tracking was accurate throughout. For the price, it’s genuinely a great deal and i would definitely consider ordering again. Always a bit of a gamble ordering online, but this one paid off. I appreciate how straightforward the whole process was and i wouldn’t hesitate to recommend this seller based on this experience. Great value, quick delivery, and the product does what it’s supposed to β€” exactly what i was hoping for.

We bought it for charging the car, to remotely control the outlet. It gets a bit hot if you put more than 20A. I don't know if this is normal, but in my opinion, more than 40 degrees is already too much.

Will be recognized by AVM's Smart Gateway. Switching works like a plug socket in the web interface and also through the AVM API. Performance measurement is currently not supported by Fristz OS 8.2. The temperature range is a fantasy value. However, the manufacturer cannot do that. As pure switch devices, they are very well usable in the Fritz Smartgateway from AVM.

Overall, the product is worth recommending. The only thing I noticed was that in my copy, the temperature probe had an error of ~5. Β° I bought this product because one of the photos in the reviews showed the ability to use the Countdown function in Tuya scenes. Unfortunately, after starting it, it turned out that I don't have such an option. I contacted the manufacturer about this issue, but as of today, this function is not provided. I wanted to use it to delay the shutdown, because the countdown in Tuya functions doesn't work properly when we want to cancel it during the scene.

Unfortunately, the measurements of the switch are absolutely inaccurate. To turn on a stove, it was installed behind a 20A circuit breaker. At full load, it shows 29 A and 6700W. This is simply impossible with a 20A circuit breaker! With an estimated actual current of 18-19 A at full load, this measurement range shows values 56% higher! As a result, the overflow and power cut-off also work with incorrect values and trigger much too early. Verified with zigbee2mqtt and confirmed with a Tuya gateway. Unfortunately, Tongou support did not want to understand the problem at all at first and blamed it on issues with the Zigbee Gateway after 4 emails. Now, before my subdistribution ends, it will go back. Too cheap and too dangerous for the power supply.

This one has more settings and safety features, but be careful, they are more switches than circuit breakers, so they need to be placed after a real circuit breaker. no configuration problem and wifi range about 15 m at my place ok. thanks to the seller and the parts for the good price.
