Was reading data from a modbus slave just fine using the 'node-red-contrib-modbus' palette. Did a fresh deploy and deleted some hiddel nodes that node red told me was superflous (did not note their names unfortunately). After that the modbus connection timed out and I was no longer able to read from the modbus slave. Never figured out why and thouhgt that I would try a reinstall/update of node red.
Followed the video tutoral on https://revolution.kunbus.de/tutorials/video-tutorials/. Installing node red using the script on https://nodered.org/docs/getting-started/raspberrypi. However, when trying to install the backend server using this command
Code: Select all
sudo apt-get install noderedrevpinodes-serverCode: Select all
pi@RevPi46224:~ $ sudo apt-get install noderedrevpinodes-server
