While configuring the Retrofit module with your home WIFI, make sure to provide the correct Wi-Fi name and password to the automation app. Both the Wi-Fi name and password are case sensitive, hence, if the configuration fails, you need to factory reset the device and reconfigure it. To factory reset the device, you need to toggle the first switch of the Retrofit module seven times within 7 seconds and reconfigure it according to the steps mentioned in the automation app.
