However, the item values for the thing with set id 0 will never display the right values as it receives responses from many devices. That allows you to have a thing that will handle a particular device (with set id other than 0), and another to send command on all devices (with set id equals 0). The set id can also be specified when using daisy-chaining. On Linux systems, this will usually be either /dev/ttyS0, /dev/ttyUSB0 or /dev/ttyACM0 (or a higher number than 0 if multiple devices are present). It is necessary to specify the serial port device used for communication. No discovery supported, manual configuration is required.

The LG serial command set appears to be similar on many models (, ), but not all commands will work on all models. The protocol supports daisy-chaining of serial devices. Supports one TV or projector per thing, also corresponding to a unique serial port. See below for a list of supported channels. This binding can send some commands typically used by LG LCD TVs (and some used by projectors).
