If the base of your Home is blinking red, it can mean one of two things:
- The setup of your Home has failed, in which case you should try to install it again.
- The "Display Air Quality alert on the device" option is enabled and the VOC level is over 2,000 ppm.
If your Home displays a flashing red light because of the VOC level, simply open your window to renew the air inside.
You can enable or disable this alert from the Home app by going to Settings and triggering the Air Quality alert switch.
