2. eWelink APP Installation
The smart switch is controlled via the eWelink APP, available for Android and iOS devices.
- Download the eWelink APP from your device's app store or scan the QR code below.
- သင့်တွင်အကောင့်တစ်ခုဖန်တီးပါ သို့မဟုတ် အကောင့်တစ်ခုရှိနှင့်ပြီးပါက ဝင်ရောက်ပါ။

3. Device Pairing
- Power on the EW-4CH module.
- Open the eWelink APP and tap the '+' icon to add a device.
- Follow the in-app instructions to put the device into pairing mode (usually by pressing and holding the pairing button on the module until the WiFi indicator light blinks).
- Connect the device to your 2.4 GHz WiFi network.
လည်ပတ်မှုမုဒ်များ
The EW-4CH supports two main operating modes: Inching (Momentary) and Self-locking (Toggle).
- လက်မဖြင့် ရွေ့လျားခြင်း မုဒ်- The relay activates for a set duration (e.g., 0.5 to 3600 seconds) and then automatically deactivates. This is suitable for applications like garage door openers or pulse-triggered devices.
- ကိုယ်တိုင်လော့ခ်ချခြင်းမုဒ်: The relay toggles its state with each activation. One press turns it on, another press turns it off. This is suitable for traditional on/off control of lights or appliances.
You can configure these modes within the eWelink APP for each relay independently.
