Tuya Smart WiFi Curtain Switch for Electric Tubular Motors (EU 502)

Upgrade your blinds, curtains, or roller shutters with a dedicated WiFi curtain switch designed for 4‑wire tubular motors. This EU 502 model puts control in your hands—via the Smart Life / Tuya app, voice assistants, and convenient scheduling—while keeping installation simple and compact.

Key features that set it apart

• New EU standard 502 size with a sleek, compact form factor for easy retrofits.
• In‑app opening duration timer (10–120 seconds): precisely control how far your curtain opens by time, so you won’t need to press repeatedly for high blinds.
• Main chip REALTKE RTL8710BN inside for reliable performance and local control.
• Mobile control anytime, anywhere over 2.4GHz Wi‑Fi (not compatible with 5Ghz networks).
• Voice control with Amazon Alexa and Google Assistant for hands‑free operation.
• Group management and device sharing in the app so family members can control the same setup.
• LED indicator behavior designed for sleep-friendly use: LED stays off unless you touch the panel; after pairing, it remains off unless activated.
• Timing schedules: automate opening and closing (e.g., open at 7:00 AM, close at 7:00 PM) to fit your daily routine.

Compatibility and how it works

• Voltage and load: 100–250VAC, 50/60Hz, up to 600W max load.
• Motor requirements: designed to work with 4‑wire electric tubular motors (Earth, Neutral, L1, L2). Neutral wire must be connected.
• Motor type: supports AC motors; cannot drive 5–24V DC motors.
• Connectivity: requires a 2.4GHz Wi‑Fi network and works with the Smart Life / Tuya app.
• Smart home integration: compatible with Amazon Alexa and Google Assistant for voice control; can be grouped with other smart blinds in the same app account.
• Installation note: designed for standard junction boxes and installable in minutes, similar to traditional blind switches.
• WiFi‑only product: no RF remote compatibility from this store (if you need a RF remote option, contact the seller).

Usage scenarios and benefits

• Remote curtain control: open/close your blinds from anywhere using the Smart Life / Tuya app on your phone.
• Automated routines: set daily schedules to wake up with natural light or secure your home at sunset.
• Precise timing for high or hard‑to‑reach blinds: the 10–120 second timer lets you achieve a target opening without multiple taps.
• Hands‑free living: combine with Alexa or Google Assistant to raise or lower blinds with simple voice commands.
• Family sharing: grant access to other household members so everyone can control the same blinds from their devices.
