I set the Wi-Fi to 2.4 GHz and despite pairing numerous other switches, this one simply refused to pair nor showing up in the bluetooth scan. Even with the help from the support people...can never get it to pair. This does not make sence Feb 17, 2025 7:45 PM Hello, thanks for your information.it works with ewelink app.if the enclosure with din rail mount? If so,please remove power source firstly,then power it up,to check if light will flash 2 short 1 long? If so,enable your phone Bluetooth and open ewelink app,select Bluetooth pairing,it will find your SSID automatically,enter your correct wifi password. Please kindly noted it supports 2.4G wifi only,when pairing,make sure to put it close to your router,your phone have to connect to the same 2.4G wifi,and check phone settings to allow ewelink app to use location service when needed Look forward to your comments ## Frequently Bought Together - MHCOZY 4CH WiFi RF Smart Switch Module,WiFi Inching/self-Locking/Interlock Relay,Work with Alexa Google Home IFTTT (DC 5-32V) - MHCOZY 4 Channel Smart WiFi RF Bluetooth Wireless Dry Contact Relay Switch Module,Phone app Remote Control,Compatible with Alexa Google Home (Tuya 4CH 5V AC/DC7-32V) --- ## 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.co.uk/products/151474053-4ch-wifi-rf-wireless-switch-relay-inching-self-locking-interlock](https://www.desertcart.co.uk/products/151474053-4ch-wifi-rf-wireless-switch-relay-inching-self-locking-interlock) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-05*
