## What it is
Tuya Cloudcutter is a Python-based toolchain that exploits a wireless vulnerability in Tuya smart devices using Beken BK7231 and Realtek chipsets to detach them from Tuya's cloud. It also supports flashing custom firmware over-the-air, enabling fully local operation of smart home devices.

## Use cases
- disconnect tuya smart devices from the cloud so they run locally
- flash custom firmware to tuya devices over the air
- jailbreak bk7231t or bk7231n smart plugs and bulbs
- cut tuya devices off from tuya servers and apps
- run smart home devices without any cloud dependency
- exploit wireless vulnerability in tuya iot devices

## When to choose
- you own unpatched Tuya devices with BK7231T, BK7231N, or RTL8710BN chipsets and want permanent local control
- you are willing to abandon Tuya's apps and cloud servers entirely
- you want to flash open-source firmware like Tasmota or ESPHome over-the-air without opening the device
- you have a Linux machine with a spare Wi-Fi adapter, NetworkManager, and Docker

## When to avoid
- you still want to use Tuya's official apps or cloud services, since detaching is irreversible
- your device has a patched firmware version that fixes the exploited vulnerability
- you need a supported chipset outside BK7231T/BK7231N/RTL8710BN or an SDK 2.0.0 RTL8710BN device
- you cannot run Docker or lack a dedicated Wi-Fi adapter and elevated privileges
