What happens if my Wi-Fi password changes?

If your Wi-Fi password changes, your breaker sensor will no longer be able to connect to your network. As a result:

• The device will stop sending data to the Lumi server.
• No new energy usage data will be recorded.
• The sensor’s LED will blink red to indicate a lost connection.

To restore connectivity:

1. Reset the sensor by pressing and holding the button on the back of the main unit for 5 seconds, until the LED starts blinking green.

2. Reconfigure the Wi-Fi connection using the Lumi app.

We recommend doing this as soon as possible to avoid any gaps in your energy monitoring data.
