The latest release of tuya/tuyaopen is v1.9.0. It is a cross-platform C/C++ SDK targeting the Tuya T-series microcontrollers, ESP32, and Linux hosts. It is intended to support development that integrates artificial intelligence features into devices. However, the provided materials contain no changelog for v1.9.0, so it is not possible to confirm what was added or fixed in this release.
The SDK is designed to implement multimodal AI features that make use of a device's voice, vision, and sensor information. According to the README, it supports automatic speech recognition (ASR), keyword spotting (KWS), text-to-speech (TTS), and STT for converting speech into text. It can connect to Tuya Cloud's multimodal AI and to models such as ChatGPT, Gemini, Qwen, and Doubao, and it also supports remote control and monitoring through cloud connectivity, along with OTA updates. Development of Google Home- and Amazon Alexa-compatible devices is included in scope as well.
The materials describe the supported features and the connection targets, but do not state how these features changed in v1.9.0. The license information is likewise recorded as NOASSERTION, so the actual usage conditions cannot be judged from these materials alone. It is difficult to define the scope of adoption until the changes for each version and the license terms have been confirmed.
