[$] BTHome: An open standard for broadcasting sensor data

Many wireless sensors broadcast their data using Bluetooth Low Energy (BLE). Their data is easy to receive, but decoding it can be achallenge. Each manufacturer uses its own format, often tied to its ownmobile apps. Integrating all of these sensors into a home-automation systemrequires a lot of custom decoders, which are generally developed byreverse-engineering the protocols. The goal of the BTHomeproject is to change this: it offers a standardized format for sensors tobroadcast their measurements using BLE. BTHome is supported by the Home Assistant home-automation software and by a few open-firmware and open-hardwareprojects.
