Frequently Asked Questions

Can I use this with 5GHz Wi-Fi?

No, this device supports 2.4GHz Wi-Fi only, which provides better range through walls and obstacles.

Does it retain settings if WiFi disconnects?

Yes, the breaker continues to work as a standard circuit breaker and follows any pre-set internal timers even without WiFi.

What is the "Maintenance Lock"?

This is a physical or software safety feature that prevents the device from being turned on remotely while an electrician is working on the circuit.
