Tuya IoT Interface
Control your Arduino projects from anywhere in the world with a free app thanks to the Tuya IoT interface!
Plug the Tuya IoT interface module into your Arduino by using the included 4 male wires. Then connect your Arduino with the IoT Tuya cloud by simply installing the Tuyav library, which is compatible with ATmega chipsets (or AVR platforming). This will enable you to connect with the Tuya app over WiFi and lets you control up to 5 outputs.
Both the cloud and app are compatible with iOS® and Android®. It's also nice to know that the Tuya app and cloud are completely free and there aren't any sneaky subscriptions. Plus, the Tuya cloud is the largest in the world!
