PeBe I don't think it's normal. Mine doesn't do it, but it also doesn't work well for me, as it can't trigger an alarm when it's in smoke. I wouldn't buy it anymore. I wrote a complaint but no one of course.

PeBe It works great. In the EWELINK application where you have RF BRIDGE, click on RF BRIDGE and then click ADD remote, then ALARM and confirm, then on the newly created remote hold your finger for at least 5 seconds on the bell mark (you will hear the sound). RF BRIDGE will wait a minute to add a SMOKE DETECTOR. In a minute you have to you press the TEST button on the smoke detector. (you will hear the sound again, the pairing sound). Then the connection is complete :)

PeBe Igot it, but I haven't started using it yet. but somewhere I read about 4 months, of course depending on usage

PeBe Iuse it with google home. But yes, the manual says it works with Alexa.

PeBe Ithink CN. But where are you from? For example, if you want from EU to Korea, or vice versa, you have to buy another reduction.

PeBe True, you have to use the bridge.

PeBe that would interest me as well. it also doesn't respond to smoke.

In a minute you have to connect the contacts on the sensor, for example with a cutlery knife :)(you will hear the sound again, the pairing sound)This will make a short circuit, as if the contacts are connected by water.Then the connection is complete.
