The In-Home Chime Power Board quiets buzzing from your doorbell chime when a wired August Doorbell Cam is installed. Here is how to tell whether you need one.
Quick answer
The In-Home Chime Power Board is a small part that reduces humming or buzzing from your existing doorbell chime when a wired August Doorbell Cam or Doorbell Cam Pro is installed. You need one only if your chime makes unwanted noise after installation; it is not required for every setup. If your chime is silent and working normally, skip it.
What the power board actually changes
Wired video doorbells draw more power than a traditional doorbell button, and that extra draw can make the chime hum or buzz even when no one is at the door. The power board reduces that noise while leaving the chime free to ring when a visitor presses the button. It is a noise fix, not a signal booster or a replacement chime.
How to tell whether your chime needs it
Listen right after you install the doorbell. A steady hum, buzz, or faint ringing that never stops is the symptom the board addresses. If the chime is quiet between presses and rings normally when pressed, you do not need the part. If the chime does not ring at all, that is a different problem; check your doorbell wiring and transformer before buying a power board.
Where the board goes in your doorbell wiring
The board installs at the chime itself, not at the doorbell button or the transformer. Turn off power to the doorbell circuit at the breaker before opening the chime cover, then follow the wiring diagram included with the part. If you are not comfortable working inside the chime box, have a qualified installer fit it.
Chime power board FAQ
- Will the power board stop my chime from ringing?
- No. It reduces background hum and buzz, but the chime still sounds when the doorbell button is pressed. Buy it for noise, not for a dead chime.
- Does it work with any August doorbell?
- It is listed as compatible with August Doorbell Cam and August Doorbell Cam Pro only. Other doorbell models are not covered by the supplied compatibility information. Match the part to your exact doorbell model.
- Can I install it myself?
- Yes, if you are comfortable turning off the doorbell breaker and working inside the chime cover. The part mounts at the chime, and the supplied instructions show the wiring. When in doubt, use a qualified installer.
- My chime is silent — is the power board the fix?
- Probably not. The board targets hum and buzz from a powered doorbell. A chime that never rings points to wiring, transformer, or chime settings instead. Diagnose the symptom before buying.
