There is provided a control device, such as a mobile device 3 or a wall panel 2, comprising one or more transmitters configured to transmit control signals for controlling operation of a controllable device, such as light sources la, lb, ic, through at least a first communication path between the control device and the controllable device, such as the mobile device 3 (or wall panel 2) to the internet service provider 50, to the public internet 40, to the Internet gateway 31, to the company IT infrastructure 30, to the local network 20, to the router 12, to the gateway/bridge 10, and to transmit control signals for controlling operation of a controllable device through at least a second communication path between the control device and the controllable device, such as mobile device 3 (or wall panel 2) to the router 12, to the gateway bridge 10. The first communication path comprising a first network and the second communication path comprising a second network. A determination logic 13 determines whether or not there exists an error in the first communication path. The control device switches from transmitting control signals through the first communication path to transmitting said control signals through the second communication path in response to a determination by the determination logic that there exists an error in the first communication path. The error detection logic 13 may receive information regarding the status of elements in the first communication path and connections therebetween from a variety of different sources. |
