sendToPi: true does not work

[freumichCH]

Hello All

I've installed the RIO Projekt on my RBP3. I was able to run the strandtest.py and singlestrandtest.py After that i tried to run the Server with the "npm run server" command. i got the expected output on the Terminal Window (RIO Logo). After switching the "sendToPi" parameter to true, i became following error:

pi@raspberrypi:~/rio $ npm run server

[email protected] server /home/pi/rio cd ./rio-server && npm start

[email protected] start /home/pi/rio/rio-server node index.js

Running npm with sudo does solve the issue, but i get no output on my LED's

Do you have any idear what happens wrong?

Yes rio-server must be run as root. Have you disabled sendToConsole in rio-server/config/index.js?
