4. Privacy and Data Security Issues: Since Smart Meter needs to collect electricity consumption data from users, protecting user privacy and data security becomes an important task. It may be easy for unauthorized access to occur, leading to leakage of sensitive information about users' habits and lifestyles.
5. User resistance: Some users may be concerned about the potential impact of wireless communication technology on privacy, cybersecurity, or health, and therefore may be hesitant to install Smart Meter.
6. Cybersecurity Threats: Because Smart Meter are connected to the Internet and often use Wi-Fi to communicate, they are vulnerable to cybersecurity threats such as hacking or denial of service attacks.
7. Inaccurate metering: Electricity consumption records are sampled and analyzed through a manganese-copper shunt, and the internal electronics are shot, making metering inaccurate.
8. Problems under external strong magnetic field interference: under external strong magnetic field interference (e.g. NdFeB permanent magnets, iron absorbers, etc.) it will disconnect the relay, and can't disconnect the electricity in case of arrears.
9. Health concerns: Smart Meter needs to communicate with other electronic devices, so Smart Meter generates high levels of pulsating EMF radiation 24 hours a day, causing health problems such as cancer and heart problems.
