I spend a few hours looking for a basic send and receive for a web relay box... this is the only one I can find that will send commands and echo back the feedback IPAD <> HHC-N8I8OP. Would be great if it could store the devices up address and had a few buttons that could be configured for common commands to send / change colour with the feedback.
