Hi @marilena.rossetti83,

Welcome to the Cayenne community! Did you download the Cayenne library from the Arduino IDE? If you go to Sketch–> Include Library–> Manage Libraries… and then search for ‘Cayenne’ it should appear and you can download it.


thx 4 reply … I istalled libraries from
i downloaded the ZIP and installed it manually as usual (I use linux mint with 1.0.1 arduino version)
I have both cayenne and ethernet libraries with examples i can browse them …
If i use example–>ethernet–>WebServer or other i can compile it
If i use example–>Actuators–>RelaySwitch I can’t compile …

It seems a path compile error … it seems it search the file inside the cayenne folder … i haven’t seen it before …
