My goal is to make an automation of a swimming pool (light, pump,...). There are two hardwares : An IPX800v3 from gce electronics and a yun equiped with and lcd shield from sparkfun and a DS1621 (temperature sensor via I2C).
A functionnal diagram is given as attachment...
and here is the code of the sketch (not finished yet but the temperature is sent to the bridge...):
