I am trying to connect a 1-wire DS18B20 sensor to a Unipi 1.1. I am running the latest version of Node-Red, but it seems no matter what I do, I cannot successfully connect. I have a bundle of standard sensors (these ones exactly:)
None of them are able to connect.
I can confirm I have installed the sensor as required here:
npm install node-red-contrib-ds18b20-sensor
When I Deploy/run my program, I get the following information in the debug window:
Error: ENOENT: no such file or directory, open '/sys/bus/w1/devices/null/w1_slave'
I can confirm that the w1 (and sub-directories) directory does not exist. I have looked everywhere on Unipi's website and elsewhere, and although I can find plenty marketing telling me that I can run a 1-wire sensor on a Unipi, there is no page telling me how to do so (with or without Node-Red).
What am I doing wrong?
