<i>Computers are hot. No, I mean, they&#x27;re hot. They heat our house in the winter here in primarily sunny Southern California (not as much as my wife would like, but that&#x27;s another story for another day).</i><p>I had to look at the date on the article to see if this was written 20 years ago, since most modern computers aren&#x27;t that hot and use very little power when not in use, unless you&#x27;ve got a big gaming (or crypto mining) rig.<p>Then I read further:<p><i>Normies don&#x27;t have a room with an IBM POWER6, Sawtooth G4 (and its FireWire RAID), Mac mini G4, Macintosh IIci, Alpha Micro Eagle 300, Cobalt RaQ and associated IoT devices and network backbone infrastructure running non-stop (to say nothing of the Apple Network Server 500 and HP 9000&#x2F;350 that also occasionally come out to play).</i><p>So the article wasn&#x27;t written 20 years ago, but his computers at at least that old.<p>The only computer that I run 24x7 is a fileserver + home automation controller, and it uses around 35W of power (including the network switch), which is still more than I&#x27;d like, I want to build one that&#x27;s more power efficient.

I&#x27;ve got two portable air conditioners, an LG in a living space, and a &quot;Comfee&quot; (which is made by Midea) for my home office&#x2F;server room.<p>The Comfee was very easy to automate. I just grabbed an ESP32 board that I had handy, some parts out of my bins, and soldered up a working IR blaster. ESPHome provided all of the hard parts, Home Assistant provided the UI. It works brilliantly. I have the air conditioner on a smart outlet which gives me real-time power consumption information, from here it&#x27;s easy to determine what the machine is doing. I also have a Xiaomi temperature&#x2F;humidity&#x2F;pressure sensor, which I can use to feed into automations to control the unit if I want to.<p>So far I&#x27;ve been unsuccessful at using an IR blaster to control the LG - ESPHome, out of the box, can&#x27;t seem to control this unit. I haven&#x27;t gone down the rabbit hole of capturing IR codes, but that&#x27;s the next step once I get the appropriate parts.

For those who don&#x27;t want to, or have the time, to build something like this, there is also an off the shelf solution: the Aqara M2 Hub[1]. I currently use this to control both my portable AC, and an electric fireplace.<p>And for those who are concerned about security, you can easily restrict this device from accessing the internet using your firewall, and it will continue to function just fine.<p>[1] <a href="https:&#x2F;&#x2F;www.aqara.com&#x2F;us&#x2F;product&#x2F;hub-m2" rel="nofollow">https:&#x2F;&#x2F;www.aqara.com&#x2F;us&#x2F;product&#x2F;hub-m2</a>

Most minisplit units work over IR blaster. HomeAssistant or ESPHome can be used to drive units capable of acting as IR blasters.<p>Personally I use Broadlink RM4 Pro units. The connect to WiFi anywhere in the house and I can use HomeAssistant to drive them. They work for both IR and 315&#x2F;433MHz devices.<p>Broadlink isn&#x27;t the only vendor, but I find the price reasonable and it&#x27;s nice to not have to solder anything.

Not too long ago I got a new AC in my office, and attempted to do some automation (turn the temp up during the weekend, etc.) via an IR Blaster. At some point I ran out of patience and gave up trying.<p>After reading this article I am encouraged to see that I was _not even close_ to getting it working, ha!<p>Maybe I&#x27;ll try again in the future, but gosh I just with these stupid units had another way to be controlled.

If you want to try something similar without all the fiddly bits (which are admittedly awesome)<p><a href="https:&#x2F;&#x2F;github.com&#x2F;smartHomeHub&#x2F;SmartIR" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;smartHomeHub&#x2F;SmartIR</a>

This sort of IR hacking is pretty badass, even if a bit fiddly.<p>How much additional heat does that old G4 add into the mix?<p>I wonder if this could be done much more efficiently with an RPi Zero or similar.

Why not just buy a new WiFi-controlled A&#x2F;C? They&#x27;re very common now.

Hmmm... what is an expect script?

Most of big brand aircons have an option for wired control. It&#x27;s just those controllers &amp; gateways are rather obscure, and hard to find.
