Microphones

The microphone settings are only in Home Assistant. They stay on the display: config sync doesn’t copy them.

Setting Entity What it does Range Default
Microphone gain number.<device>_microphone_microphone_gain Amplification before anything else 0–20 dB on the Smart Display 10, 8 and ThinkSmart View; 0–32 on the JBL Link View; 0–40 on the Smart Display 7 0 dB
Microphone leveling switch.<device>_microphone_microphone_leveling Keeps your voice at a steady level whether you’re near or across the room On, Off On
Noise suppression switch.<device>_microphone_noise_suppression Takes the room’s steady noise (a fan, traffic) out of what the microphones hear On, Off On
Room sensitivity number.<device>_microphone_room_sensitivity How much louder than the room’s background noise a sound has to be before the listening visual reacts 4–20 dB 8 dB

The room’s sound level and noise floor are sensors (room_level, room_floor), which help when tuning.

  • The wake word misses you from across the room. Make the wake word easier to trigger first: lower Wake word sensitivity in Home Assistant, or raise its slider on the screen; then raise Microphone gain a few dB at a time. Keep Microphone leveling on.
  • It wakes on its own, or on the TV. Make the wake word harder to trigger: raise Wake word sensitivity in Home Assistant, or lower its slider on the screen.
  • It cuts you off, or keeps listening too long. Adjust Max listening time, and Room sensitivity if the room is loud.
  • Voices sound distorted in the recordings. Lower Microphone gain.

Visualizer lift (visualizer_lift, 0–40 dB) adds gain for the visuals only, so they move in a quiet room without changing what the wake word hears.
