Geek DAIKIN Air Sensor meets ESPHome & Home Assistant
大金空气传感器刷机 使其适配 ESPHome 和 Home Assistant
大金空气传感器（型号：BRY88AB151K/BRY88AA151K）是大金中央空调系统的组成部分之一，它需要配合大金空调网关DTA117D611或DTA117C611使用，用于检测室内空气质量，检测内容包括：温度（Temperature）、湿度（Humidity）、二氧化碳浓度（CO2）、细颗粒物（PM2.5）和总挥发性有机化合物（TVOC）。它采用标准USB接口供电，通过Wifi网络无线连接到同一网段内的大金空调网关，但是只能使用大金中央空调的App“金制空气”进行空气指标监测。
经过拆解后发现，该传感器内部设计精良，做工精细，并且采用了业内知名的高性能传感器组件，故萌发了刷机的念头，使其能够基于ESPHome的平台接入Home Assistant智能家居系统。
Daikin air sensor (model: BRY88AB151K/BRY88AA151K) is one of the components of Daikin central air-conditioning system. It needs to be used with Daikin air-conditioning gateway DTA117D611 or DTA117C611 to detect indoor air quality. The detection content includes: temperature, humidity, carbon dioxide concentration (CO2), PM2.5 and TVOC. It is powered by a standard USB interface and wirelessly connected to the Daikin air conditioner gateway in the same network segment through the Wifi network. But it can only use the App “Golden Air” of Daikin central air conditioner for air monitoring.
After disassembly, it was found that the sensor has excellent internal design, fine workmanship, and uses well-known high-performance sensor components in the industry, so the idea of hacking it came up, so that it can be connected to the Home Assistant smart home system based on the ESPHome platform.
