A command-line utility (written in Perl) to send commands and query status from a Mitsubishi G-50A or GB-50A Central Controller for your airconditioner.
If your airconditioning unit is controlled with a G-50A or GB-50A central controller then this is just the ticket for you to be able to send commands to it and query it’s status.
I use it (along with another script to query my weather station for indoor/outdoor temperatures) to start the airconditioner running before we get up on particularly cold mornings.

I don't expect there to be thousands clamouring for this particular piece of software, so the best way will be to e-mail me directly, or find me on IRC.
