This smart switch is fully compatible with both Amazon Alexa and Google Assistant, allowing you to control your lights and appliances using simple voice commands. Just link your Tuya Smart or Smart Life account in your preferred voice assistant app.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use the RF remote without a WiFi connection?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The included 433MHz RF remote works independently of WiFi once it's paired with the receiver using the learning button. However, app-based features like scheduling and remote access require a WiFi connection.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this smart switch compatible with 240V systems?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. This WiFi smart relay receiver supports a wide voltage range of AC 85–240V at 50\/60Hz, making it suitable for use in the US, UK, Europe, Australia, and most other countries worldwide.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum load this switch can handle?\u003c\/h4\u003e\n\u003cp\u003eA: The switch supports a maximum current of 16A or 20A (depending on the variant) and a maximum load power of under 1100W, making it suitable for LED lights, fans, and most standard household appliances.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the mini round button switch work on its own?\u003c\/h4\u003e\n\u003cp\u003eA: No. The mini round RF433MHz button switch requires the WiFi + RF433MHz receiver to function.
