Blinking yellow light on Nest Doorbell wired

A blinking yellow light means that  your Google Nest Doorbell (wired) or Nest Doorbell (wired) 2nd gen isn’t getting enough power. Your doorbell won’t be able to stream video or send you alerts, but it should continue to work as a regular doorbell. ​

• You may need to upgrade the transformer that the chime’s wires are connected to.
• Contact a local professional or certified electrician to have them check the voltage and install
  a new transformer.
