| The speakers are connected using the TV's headphone jack. Unfortunately, the software on my TV model is particularly dumb, in that it only allows changing the volume of its internal speakers using the volume controls on the remote. Initially, I wanted to use optical audio, but that does not allow for volume control due to its nature (optical audio transmits digital audio over infrared which simply carries the soundwave without any volume information - traditionally, it is the job of the receiver unit to regulate the volume). Then, I looked into using the HDMI ARC (audio return channel) feature, but, again, this is poorly implemented and does not allow for volume change. Lastly, I chose to connect the speakers via the headphone jack, which allows change via the "Sound" section of the TV menu, but not directly using the IR remote control. | The speakers are connected using the TV's headphone jack.

| The goal for this task was to be able to smart control the AC unit that I have in my home, bypassing the included remote control. The end goal was to have them controlled from anywhere around the globe. | The goal for this task was to be able to smart control the AC unit that I have in my home, bypassing the included remote control.

| The AC units are Bosch Climate 3000i [[https://www.bosch-industrial.com/gb/en/ocs/commercial-industrial/climate-3000i-18569608-p/| ]]. These are actually manufactured by Midea and sold under the Bosch brand in Romania [[https://community.home-assistant.io/t/bosch-5000i-air-conditioning/367752/9| ]].
