LED Blinking Patterns

The LED indicator on your Sensibo device communicates important information about its connection status. Here’s a detailed guide to understanding what each blinking pattern means:

LED Pattern Guide

No Blinking

• Device is successfully connected to the Sensibo server
• This is the normal state during regular operation

No LED Light?

During normal operation, no LED light indicates successful connection to Sensibo servers. However, if your device isn’t responding at all, first check that it’s properly connected to a power source.

One Blink (Every 2 Seconds)

• Device is in setup mode
• Action needed: Launch the Sensibo app and follow the setup wizard
• The wizard will help you provide WiFi network credentials

Two Blinks (Every 2 Seconds)

• Device is attempting to connect to your router
• If stuck at this stage:
  • Check if the WiFi password is correct
  • Verify you’re not trying to connect to a 5GHz network (not supported)

Three Blinks (Every 2 Seconds)

• If stuck at this stage:
  • Check your DNS configuration
  • Ensure your router can resolve domain names

• Device is either:
  • Connecting to the server, or
