Understanding the indicator light on my switch or dimmer

The indicator light on the switch or dimmer shows its status: flashing blue means Zigbee connection attempt, red indicates no gateway detected, two green or yellow flashes signal a key lock, solid green corresponds to Away mode, and off means no connection or loss of connection for more than 3 hours.

The indicator light (LED) on your switch or dimmer allows you to indicate the status of the device and facilitates diagnosis in case of a problem.

Here is the meaning of the different behaviors of the indicator light.

The indicator light flashes blue, then turns off upon connection.

When the indicator light flashes blue , it means that the switch or dimmer is trying to connect to your Zigbee gateway.

If the connection fails, the light will turn off after a certain time.

For more details on the pairing procedure, consult the instruction manual for your Zigbee gateway.

The indicator light flashes red during connection

A flashing red light indicates that the device is attempting to connect to the network, but no gateway is detected.

In this case :

  • Make sure the gateway is properly plugged in.
  • Check that an association session is in progress

If the problem persists:

  • The device may be too far from the gateway
  • Move the gateway closer or add a compatible device to act as a repeater.

⚠️ Note: a Zigbee device cannot act as a repeater for Mi-Wi devices, and vice versa.

The indicator light flashes twice in green or yellow when pressed.

When the indicator light flashes twice in green or yellow after pressing a button, it means that the device’s keys are locked.


To unlock them:

  • Access device settings in Neviweb
  • Or use your compatible gateway

The indicator light is permanently green

A steady green light indicates that your system is in Away mode.


To change this status:

  • Access the Neviweb dashboard
  • Select Present mode

The indicator light is off

The indicator light is only on when the device is connected to a gateway.


It can be switched off in the following situations:

  • The device is not connected to a gateway
  • The connection to the gateway has been lost for more than 3 hours.
