Connecting an Arduino device to the Tuya app ecosystem — what actually works One of the reasons I picked the T5AI board for my desk device experiment is that it connects into the Tuya app ecosystem through the standard DP (Data Point) model. If you've used any "Powered by Tuya" smart home device, the underlying data model is the same.In practice: each controllable property on the device gets a DP ID. You report values up to the cloud using that ID, and the app reads them. Commands from the app come down as DP events in your callback.For my build, I used a DP for volume control — the app can adjust the speaker volume, and the board picks it up in the IoT event callback and calls TuyaAI.setVolume(). It's a small example but the pattern extends to anything: brightness, switch state, sensor readings, whatever you need.The part that's genuinely useful for home automation is scene linking. Because the device is a standard Tuya product, it can participate in automations with other Powered by Tuya devices.…
