Is that you look at and test the Logitech Harmony Hub system.
I work in a nursing home and one of our residents can no longer use their hands. She has a run of the mill flat screen tv (probably 5 years old), and can no longer point the remote to change channels. There are a number of different options using wifi/Bluetooth to change the channels using voice commands, however her tv just uses and infared signal. Are there any adaptor available that would allow her tv to be changed by using wifi or Bluetooth. Thanks.
