Well, it does sort of work with air conditioners right now, but not very well. This is an area of Pierogi that still needs a lot of work...

Most manufacturers do seem to play around with their IR protocols over time, so the more precise the model number, the easier it is for me to find a matching protocol. That said, however, I've taken a quick look for Midea config files, and I'm coming up completely empty. However, I did find one rather amazing web site where a guy describes in great detail how he reverse engineered his own Midea remote control sufficiently to create his own on/off switch. His info shows that the thing is sending 48 bits of data in each individual command, which is around the same amount used in the really complex protocols I'm finding from other manufacturers. So, there may be a chance that a protocol for another manufacturer will work with Midea.

That said, I'm still trying to figure out those really complex protocols myself, so I'm not going to make any promises on a time frame. Air conditioner remotes are tough!
