RPi NodeRed-MQTT-OWFS tinkering

Posted by pete_c , 15 March 2018 · 103 views

Over the last few months here have been tinkering with my 1-wire stuff.
 
Moved the post to here from Automation.  I cannot attach pictures to my posts these days such that this blog will be pictureless.
 
That said I see no interest so will continue to post what I am doing with this stuff.
 
Old configuration was using multiple 1-Wire controllers serially connected to one computer and talking to 1-wire devices connected via cat5e all over the house.
 
New 1-wire configuration is using a created RPi 1-wire hub connected to a few sensors.
 
Currently running POE connected RPi in the attic is just generating a text file from Digitemp for second floor sensors. Configured a new RPi for main floor sensors in the last few days.
 
1 - installed Digitemp and configured it for test sensors.  First testing is creating Homeseer variables via a text read every few minutes.  This has been working fine now for over a year.

2 - installed OWFS and configured it for test sensors.
 
3 - installed mqtt
 
4 - installed node red and the OWFS modules
 
 
5 - configuring Node Red to send out MQTT stuff.
