It works very nice easy to connect with application it works with google assistant. Dosent work if the distance between sensor and magnet is bigger than one finger
I received it in perfect condition, compact and good quality device, it needs to be tested
Thank you, Banggood

Very fast delivery, good product.
It came quickly, the whole thing, not yet included, the set has two stickers and a dugout, running on two batteries
This item came with 4 mounting screws; two for the contact sensor and two for mounting the magnet. The ones for the magnet are too large in diameter. They don't fit through the predrilled holes in the magnet base. I had to make these holes larger. Manufacturer should either makes the holes larger or provide thinner screws. I just installed this sensor on my garage door and it works fine.
