The motor auto calibrates and then Alexa Voice command can have blinds Open in percentage terms eg 30%, 70% etc. After returning 2 other brand switches finally got this feature running on Sonoff! Super cool. Blinds can now be automated to open on sunrise, close partially at sunset and completely close at given time. Dismissing Alexa alarm in morning can be automated to have the blinds open 50% for gentle sunlight waking up. Works great! ## Frequently Bought Together - SONOFF WiFi Smart Curtain Switch with Power Metering TUV Certified, DUALR3 Dual Relay DIY Curtain, Blinds, Roller Shutter,Two Way Smart Switch,Works with Alexa&Google Home(1 Pack) - SONOFF ZBMINIL2 Extreme Zigbee Smart Light Switch (2 Way), Compatible with Alexa, SmartThings Hub, Google Home&SONOFF ZBBridge-P, ZigBee Hub Required, No Neutral Required 4-Pack - SONOFF WiFi Smart Curtain Switch with Power Metering TUV Certified, DUALR3 Dual Relay DIY Curtain, Blinds, Roller Shutter,Two Way Smart Switch Work with Alexa&Google Home(2-Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/370232269-wifi-smart-curtain-switch-with-power-metering-tuv-certified-dualr3](https://www.desertcart.vu/products/370232269-wifi-smart-curtain-switch-with-power-metering-tuv-certified-dualr3) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
