Manipulating smart meters in the power grid to achieve energy theft is illegal and seriously illegal. It is absolutely not possible and should not be done. Smart meters have high-precision metering and data acquisition functions, and are subject to strict safety protection and regulatory measures to ensure their normal operation and accurate data. Attempting to illegally manipulate it will not only be discovered by the monitoring system of the power sector, but will lead to serious legal consequences, including high fines and criminal penalties. It also destroys the fair energy supply order and harms the interests of the majority of legal electricity customers and power supply companies. Maintaining the normal operation and fair measurement of the power system is essential to ensure a stable supply of energy and promote healthy socio-economic development. We should abide by laws and regulations and use electricity legally and in compliance.
