Your phone connects Fingerbot by Bluetooth. And the range of Bluetooth is relatively short compared to Wi-Fi. You need to be in the room to control the device. Suppose you want to extend the control range. You could purchase our HomeHub, which acts as a bridge between your phone and Fingerbot, convert instructions from Wi-Fi to local Bluetooth. Then you'll be able to control the Fingerbot wherever you are as long as there are internet connections.
