The first one didn't work, so I complained.
On the second one, the battery contact still didn't work, so I had to move the tab. After a month of dropouts and bending contact, the tongue broke off.

The sensor pairs with the meross hub without any problems, but after two or three days (sporadically) it stops communicating and appears as " disconnected" in the application. Even restarting the hub does not help, the problem is in the construction of the battery attachment, when the plate that holds the battery is powered on the printed circuit only on one side. It is so thin that after inserting the battery it does have a contact, but after a few days it becomes " overspringed" and the sensor stops being powered, it loses contact with the battery. In my opinion, it is structurally poorly designed. A disconnected sensor can only be put back into operation by removing the battery, springing the battery holding plate, and after inserting the battery the sensor starts communicating normally. If it happened to one sensor, so be it, it could be a faulty piece. But I have 4 and they all do it. Since I have automation connected to these sensors in Apple Home, after disconnecting any of them the automation is non-functional, then security is meaningless. Because of these outages, I do not recommend this product. The manufacturer could think more about the design of the battery holder next time. Due to the negative customer experience I will never buy from this company again.
fine price
