How to stream audio from one room to another?

Question

Bluetooth

Hello everyone,
Permanent nursing required (family member). I work from home. Sometimes you need to leave the room to focus on work or call a client. Occasionally, he tries to move independently, which can lead to unpleasant incidents.
Idea:
Install a microphone that constantly broadcasts all the sounds in the room to the receiving device. (for example, a bluetooth speaker or headset). However, it is difficult to “pair” a bluetooth microphone and a bluetooth speaker without an intermediate device: at a minimum, you must agree to connect. I am looking for a technical solution that allows constant audio monitoring of what is happening in the room.
It may not be ideal to stream an audio stream, and I'm open to other approaches.

Answer 1

For what purpose? Well, you probably need to use some kind of repeater xD
Or install a microphone and connect to it via a Wi-Fi channel
