Adding this Smart Wifi Module to any Garage door motor / Electric Gate Motor or Electric fencing energizer will take you less than 15 minutes. Enable your old legacy devices to be wifi-controlled from your phone with an app on your smartphone. Forgot to close the garage door or gate at home when you left ? Or your remote is not working ? No problem, control it from your phone from anywhere to operate it to the required state. The wireless module supports inching /self-locking mode. You can add the device to the eWeLink APP on Android and Apple Smartphones to remote control connected home appliances or devices. In self-locking mode, you can remotely turn on/off connected devices immediately. When in inching mode, you can turn on the switch for 0.5s and then auto-turn-off after another 0.5s. This simulates the press of the remote control button thereby opening or closing your gate or garage motor.
