Hong KongSofaBaton makes universal remote controls that consolidate a living room's devices into one handset. The range runs from the entry-level U1 and U2 up to the X1 and X1S, which pair the remote with a hub so it can reach devices over infrared, Bluetooth and Wi-Fi rather than line-of-sight alone. Remotes are configured from a phone app against a large device database, with customizable keys and one-touch activity macros that switch several devices at once.
