Combined bridge power/ethernet wire
The included 30 cm power wire and ethernet cable contradict the advice that optimal positioning of the bridge should be vertical and not directly behind the router. It is very hard to get the bridge into a vertical position and on the wall while not being very close to the router.
Tado also suggest the use of powerline wifi to get the optimum position of the bridge.
Ultimately you will inevitably have a powerline or router ethernet connection with either a built in USB power supply or a separate power supply from a twin electricity socket. That means trailing and fixing two wires, likely of different colours around your house. I for one would buy a combined power/ethernet cable with a port at one end that connects to the two female ports in the bridge and another which splits to a "y" cable with ethernet/USB port at the end.
