Thanks Grant. The output of the web page is simply a text file that outputs text - the current temperature that is updated every 5 seconds. I’m not necessarily looking to get that level of granularity in grafana [although it would be great if I could]. I can run the update every 30 seconds, if need be. But, currently - I have plotly scraping / referencing this text every 5 seconds and it works perfectly.
As I am using a Python script to generate that temp.txt, you are stating that if I output the temperature as json, Grafana can read it? What about CORS restrictions?
I am using DS18B20 1-wire’s to read thermals throughout the house. I hadn’t thought of trying MQTT. I can toy with, this weekend, that as long as you are fairly confident that I can use one single graph to monitor several sensors, using MQTT?
If so, I’d gladly accept your help with it - let me do a brief study on it, first.
