Hello, after typing the commands pi@raspberry:~$ sudo systemctl enable nodered.service
it replied as such:- Failed to enable unit: this file nodered.service does not exist
Can you run this command again?
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
It looks like your Node-RED installation might have failed. Let me know if this command works for you, then run this command again:
sudo systemctl enable nodered.service
yesterday I have installed the node-red system according your ebook “House Automation System”. After failing the URL I found the above mentioned command referencing ../linux-installers. All went fine and I could reproduce the first example. Then I found that the Raspberry Nodes are missing.
I looked for them in the node-red library. I found it and processed the command
pi@raspi-28:~ $ cd .node-red
pi@raspi-28:~/.node-red $ npm install node-red-contrib-redplc-rpi-gpio

After enabling node-red and refreshing the browsertab nothing has changed. Node-red doesn’t the rpi-gpio nodes. Can you give me a hint how to solve the problem?
Many thanks, Roland
Problem solved. I have found the rpi-gpio Nodes and installed using manage pallete.
