Smart Energy Meter & Breaker / Protection

What protection functions does the smart energy meter have?

Short answer: Protection functions depend on the exact model. They may include over-voltage, under-voltage, over-current, over-power or usage-limit/prepaid kWh functions.

Explanation

Smart energy meter protection functions are not the same for every model, so they must be checked product by product.

Some models may include over-voltage, under-voltage, over-current, over-power or other configurable cut-off functions. Some Smart Life meters may also have a prepaid kWh or usage-limit function, where power is cut off after the set amount of kWh is used.

Do not assume every smart meter has all protection features. Always refer to the product description or ask customer service to confirm the exact model.

Common mistakes

  • Assuming every smart meter has the same protection functions
  • treating usage-limit functions as electrical safety protection
  • expecting eWeLink and Smart Life to have the same settings.

Troubleshooting / next steps

  • Check the app setting page and product description for the specific model. If a certain protection function is required, confirm before purchase.
