Power-off memory function

If the product has a power failure memory function, it will maintain the state before the power failure. For example, the socket: if it was off before the power was off, it will remain off after power on. The power-off memory function is a hardware function and needs to be carefully considered according to the product use. For example, the power failure memory of the socket: * If the socket is used by remote unattended equipment, the customer wants the socket to maintain the state before the power failure, and then use the power failure memory. * If the socket is connected to high-power electrical equipment, the customer wants the socket to be turned off by default after power onl, so the power-off memory function cannot be used.
