For some reason importing this seems to cause problems though. I had to build it by hand and it worked fine.

Read temp readings from 1wire sensor on GPIO

There doesn't seem to be a single clear way to do this
Install 1wire node


Install npm
sudo apt install npm
Install https://www.npmjs.com/package/node-red-contrib-1wire
sudo npm install -g node-red-contrib-1wire https://nodered.org/docs/getting-started/adding-nodes
Restart node-red https://nodered.org/docs/hardware/raspberrypi
node-red-stop
node-red-start
This seems to leave you in the start command but control-C seems to not stop Node Red
In Node Red http://10.0.1.13:1880/# go to Hamburger menu > Manage palette.
Select install tab and search for "1wire"
Click "Install"
Find "1 wire" node under Functions
