i'm controlling an arduino (amongst other things) from a puredata patch with the aim of making a programmable climate control system.
i need to turn on and off various 240v/10A heating or cooling devices automatically. BUT i'm not a qualified electrician and as this project is taking place at a public institution, i can't construct the 240v side of the system myself as this would void the building/liability insurance.
so i'm looking for a cost-effective off-the-shelf solution that can somehow interface with either arduino or the computer i'm running the puredata patch on - which happens to be an OLPC XO laptop running xo-ubuntu intrepid 8.10.
my ideas so far are:
some kind of midi-controlled power board similar to what theatre lighting techies use. i know nothing about these, and they sound expensive to me. but i can easily send midi messages from arduino.
some kind of X10 or IP-enabled home automation switches. maybe i could bypass arduino altogether and somehow have puredata communicate with a home automation switch over a wifi network...?
a commercially manufactured power switch designed to interface with a microcontroller using a relay. i've tried looking for these, but not knowing what they would be called, i've had no luck yet. this would be the ideal solution i guess - simple, and sounds cheap.
