Generic ESP32
Olimex ESP32 Power-over-Ethernet ISO

I did the following:

Plugged device into a PC with USB OTG cable

Pointed web browser to Ready-Made Projects — ESPHome  https://esphome.io/projects/index.html

Selected my device type "Bluetooth proxy"

Hit Connect, selected proper "USB cp2102 COM" port, & hit Install.

A couple minutes later, I had a working voice assist satellite device, with working mic, speaker, and cutesy display.

I immediately asked it “Hey Nabu, turn off XX lights”

Note： ESPHome Bluetooth Proxy not working with Passive BLE monitor integration

note
ESPHome Bluetooth Proxies cannot forward data to BLE monitor. Check out this page for alternative solutions.https://custom-components.github.io/ble_monitor/parse_data

This is because an ESPHome Bluetooth Proxy is forwarding its data to the official Bluetooth integration in Home Assistant. The Bluetooth integration is forwarding the data to a brand specific integration.

BLE monitor is using its own Bluetooth collecting mechanism based on aioblescan which is working at a lower level (HCI). BLE monitor is not using the Bluetooth integration to receive its data, and is therefore not able to receive data from ESPHome Bluetooth Proxies. You can use ESPHome BLE Gateway instead, which is able to forward data to BLE monitor in a similar way.

ESP32刷Bluetooth Proxy，每个房间放一块esp32，实现分布式么。
——是的，倒不必每个房间一块，覆盖到每个房间就行。

一个Proxy官方说好像只能有3个活跃连接。都是自动切换的么？
——官方文档说的很清楚，是自动切换。你好像没理解活跃连接这个概念，像蓝牙耳机这种是连接，而温湿度传感器包括这个帖子讨论的在家检测，不是连接，而是广播，不受3这个数量的限制。如果确定没有需要用到活跃连接的设备，最好是干脆把这个禁止掉。

ha带多个Bluetooth Proxy，需要配置么，还是自动发现运用。
——这种问题不用考虑这么复杂，自己动手一试就知道了，不需要配置，都是自动的。
