Дорогой Aliexpress! Я думаю, что не точные переводы описаний товаров тут созданы умышленно. Если продавец хотел, то сделал бы описание товара очень точным. Это очень не дружественно со стороны магазина поддерживать и поощрять не точные переводы чтобы вводить в небольшие заблуждения. В результате не точного описания мне пришлось купить не соответствующий и ненужный мне товар в этом магазине - сенсор двери, который не работает с WI-FI и требуется дополнительная дорогостоящая покупка управляющего блока. Это уже не первый раз когда заказывается не такой товар с неудовлетворительными для конкретных целей характеристиками. Теперь я буду всегда сообщать о плохом описании товара потому что это делает неприятности покупателям.

All right but without batteries for a few more cents they could have been included and bought the item the same, I know the brand and it's trusted.

Connection of the sensor to tuyasmart by Wi-Fi, when receiving alerts there is a delay of ~ 20-40 seconds. If there are difficulties in recording the sensor, force the IP address of the sensor in the router settings.

This is not a description of the goods, but a set of words, completely unconnected. We need to work on the texts of the description of goods.
