IR Control is how your TV Remote communicates to your TV. Your Remote has a little bulb on it that flashes. When it flashes, it sends a command out to your TV. Your TV has a little IR sensor built into it that see the flashing command from your remote.
The Smart Home controller can simulate this with an IR Bulb. It’s a small little light bulb that you stick on the TV’s IR Sensor. The other end of the IR bulb hardwires into the Smart Home Controller. When you send the TV a command, the Controller simulates the Remote by sending a command out to the IR Bulb. The IR Bulb flashes like your remote, and the TV’s IR Sensor receives the command. When Serial and IP connections are not an option, the IR Connection is used to Control Blu-rays, Apple TV, Satellite Receivers, & Surround Sound Systems.
Unlike Serial connections and IP connections, IR does not support 2-way feedback. It will turn your TV on, but it can’t tell your Smart Home App the status of the TV.
