Maybe join forces with Karl and his Arduino plugin to bridge the CIR transmit and receive functions in the Cynical Caché Plugin to utilize the Arduino + Wifi/Ethernet combo.
For a little less than $50 in parts we could build an interface supporting numerous emitters & receivers. Technically you could use the serial pins on the Arduino for Serial interfaces and other pins to control relays, so you could replace up to a GC-100-12 maybe.
Karl's Arduino sketch creates a simple web interface on the Arduino, so it might could be adapted to talk with a modified form of your plugin direct...or maybe extend the Cynical plugin to speak to devices created by Karl's?
It would be great because I already have 3x Arduino UNO + Ethernet units with IR receivers and transmitters that I could deploy to take control of my 3 home theater setups with no more additional purchases.
I just thought I'd toss the idea out there and see if there was any interest. The iTach is nice...but $91...if I'm going to spend I'd prefer to get more Fibaro RGBW units and some fan-speed controllers.
Hopefully at least consider it...
Thanks!
