Abstract: A wall device is described comprising a power source base body for installation in a wall, where the power source base body comprises at least one accommodating space. The accommodating space is configured for placement of a first metal piece, a second metal piece, a third metal piece, and a fourth metal piece, where the first metal piece is a first live wire circuit, the second metal piece is a second live wire circuit, the third metal piece is an earth wire circuit, and the fourth metal piece is a neutral wire circuit. Partition plates are provided in the accommodating space to separate the positions of the first metal piece, the second metal piece, the third metal piece, and the fourth metal piece, so as to prevent the first metal piece, the second metal piece, the third metal piece, and the fourth metal piece from contacting in the accommodation space.

Abstract: Disclosed is a wall-mounted device, which is mainly provided with a base and a cover plate, and the at least one module circuit board is provided in the cover plate. The power terminal of at least one module circuit board is electrically connected to an exterior live wire circuit of the base, so the interior live wire circuit is able to independently supply power to the module circuit board of the cover plate. As the result, the base is able to fit or replace with any cover plate provided with module circuit board, and connects to any electronic device or network to remotely control and operate.

Abstract: The present invention provides an intelligent device, and the major aspect is using a design of an intelligent cover. The intelligent cover includes a circuit board which is provided with at least one induction coil, a microcontroller (MCU) and a switch. The induction coil is used to induce the amount of the current when the current is passed the induction coil, the open (non-conducting)/closed (conducting) state of the current transmission is controlled by the switch, and the MCU can monitor and remote control remotely, so that when the intelligent cover is combined with a base seat, which is capable of monitoring the electricity consumption, the voltage value and the temperature to achieve the reduction efficacy of the of monitoring costs.
