Frequently Asked Questions
Q: What app is compatible with this WiFi smart voltage protector?
A: This device is compatible with the Smart Life and Tuya apps, available for free on both iOS and Android. Once connected to your home WiFi, you can monitor energy usage, adjust voltage thresholds, receive real-time alerts, and remotely control the breaker switch directly from your smartphone.
Q: Can I adjust the over-voltage and under-voltage trip thresholds myself?
A: Yes. The over-voltage protection is adjustable between 120V and 300V (factory default: 275V), and the under-voltage protection is adjustable between 85V and 200V (factory default: 160V). You can customize these values through the Smart Life app to match your specific electrical requirements.
Q: Is this device suitable for both residential and commercial electrical panels?
A: This smart protector is designed for standard single-phase electrical systems operating between 80–300V, making it suitable for a wide range of residential and light commercial applications. Always ensure installation is performed by a qualified electrician in compliance with local electrical codes.
Q: Does the kWh energy meter record historical power consumption data?
A: Yes. The integrated kWh energy meter tracks real-time and cumulative power consumption, which can be viewed through the Smart Life app. This helps you monitor energy usage trends and manage electricity costs more effectively.
