Delete node-red-contrib-modbus and serialport folder in /usr/lib/node_modules Then make sure to install a version that supports NodeJS V6 and build them from source: npm install -g node-red-contrib-modbus@2.5.0 --unsafe-perm --build-from-source Kind regards!

Look for the the node-red process in top You can set up node-red to run automatically after system startup in iot2000setup then you don't have to run it manually. I would also recommend to delete the old flows rm ~/.node-red/flows_iot2000.json Kind regards!

Maybe install a fresh image on the IOT and then install the Nodes as discribed above. I also don't understand why you are getting this error message RocíoCar 12 Jun 16:50:03 - [error] Unable to listen on http://127.0.0.1:1880/ 12 Jun 16:50:03 - [error] Error: port in use as this should only happen if you execute node-red twice. Check netstat -lntu To see if Port 1880 is really in use. Kind regards!
