A collection of scripts to flash Tuya IoT devices to alternative, open-source firmware without soldering.
tuya-convert is an open-source tool that allows users to flash Tuya-based smart home devices with alternative, open-source firmware without requiring physical hardware modification. It exploits a vulnerability in Tuya's firmware to enable over-the-air (OTA) flashing, freeing devices from proprietary cloud services. The project addresses security and privacy concerns associated with Tuya's cloud while enabling local control and customization.
DIY smart home enthusiasts, IoT tinkerers, and privacy-conscious users who own Tuya-compatible devices and want to install open-source firmware like Tasmota or ESPurna. It requires basic Linux command-line knowledge and a compatible Wi-Fi adapter.
It provides a unique solder-free method to reflash devices, lowering the barrier to entry compared to traditional serial flashing. The tool is community-maintained, includes pre-built firmware binaries, and supports Docker for easy deployment, making it accessible to users without deep hardware expertise.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Exploits a software vulnerability to flash devices over-the-air, eliminating the need for physical hardware modification, as emphasized in the key features and procedure.
Creates a local backup of the original stock firmware before flashing, providing a recovery option in case of issues, mentioned in the flashing process.
Offers a Docker image for isolated, dependency-free execution on any Linux system with Docker, simplifying deployment and reducing setup complexity.
Includes binaries for Tasmota and ESPurna in the package, making it convenient for users to start flashing without sourcing firmware separately.
Tuya has released multiple firmware patches that block the exploit, rendering many newer devices incompatible, as detailed in the PROCEDURE section with warnings about PSK ID 02.
Requires specific Linux setups and Wi-Fi adapters capable of acting as access points, limiting usability for users on other operating systems or with incompatible hardware.
Flashing can permanently damage devices or require soldering a serial connection for recovery, as warned in the README, which undermines the solder-free claim in failure cases.
