After connecting to a Wifi signal, the smart motor can directly work with Alexa, Google Home, IFTT, and TuyaSmart App. Simply control it manually during power-cut. The motor is put on the right back side default. You can turn around the whole track rod if you want to put the motor on the left side (the motor will be on the front side then).
