there is a possibility to integrate light hack to receive contact closure and send OSC message to EOS? EOS (4) contact closure are too small for me... do you have suggest??
There are some manufacturers for Arduino based automation systems, which use optoisolated in- and output used for 24V systems. You can use it with USB or over ethernet. The code should be very simple to write but depends what you want to do (firing macros ...)Controllino https://www.controllino.biz/#Industrial Shields https://www.industrialshields.comRugged Circuits https://www.rugged-circuits.com
