What is the power mode of the NB module?

The NB modules of Tuya are divided into the PSM type and the DRX type. The two types correspond to two different cloud logics. Before applying for the module, please determine the service type of the product, whether it is used for the PSM or the DRX. The PSM type modules will enter the PSM mode to reduce power. They are often used for battery-powered devices and have a fixed reporting notification type. The DRX type modules will not enter the low-power mode, and will respond to the data sent and received in real time. They are often used for devices that are not sensitive to the power and are the real-time controlling type.
