It was easy to set up and works well. ### ⭐ Disconnects from WiFi every 12 hours *by B***E on June 8, 2025* Wifi is not stable. Disconnects every 12 hours like clockwork. I believe problem is due to error in firmware. You must interrupt power for it to reconnect and it stays connected for another 12 hours. ## Frequently Bought Together - Otcboimo Smart WiFi Wireless Relay Switch Module, Tuya 1CH AC 85-250V/ USB 5V Smart Life Remote Control Dry Contact Momentry Switch Compatible with Alexa and Google Home - ECO-WORTHY Heavy Duty 330lbs/1500N Solar Tracker Linear Actuator Multi-Functions with Mounting Brackets (12V, 12") IP54 Waterproof 300mm Stroke Linear Motion Actuator - DieseRC 1 Channel WiFi Smart Switch, DC 5V 12V 24V 36V Passive Output Relay Module Ewelink APP WiFi Control Compatible with Alexa/Google Home, Inching/Self-Locking Switch --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/560354181-smart-wifi-wireless-relay-switch-module-tuya-1ch-ac-85](https://www.desertcart.ae/products/560354181-smart-wifi-wireless-relay-switch-module-tuya-1ch-ac-85) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-28*
