I have ben working on a small projekt to improve the graphs and log capabilities of my GHL Profilux 3.1. The system is running on a small rasberry pi 2, with a 800x600 touch screen display. The data is provided on a webserver, so the graphs can be acces from everywhere, as long you have acces to your pi. The idea is the make it easier to read the graphs, and have something that looks better than what GHL offer.. the profilux touch is ugly...
The system is working as it is now, but i was thinking if there were interest for it, to make it more userfriendly to set up, and publish it to free use? Right now you would have to edit some scripts in order to get the right sensor data. As ghl have removed the rss feed from the computer, it has also made it a bit more complicated to parse the data. But if there is interest i will finish it up, and publish it as gpl, probaly on github or something like that.
The system can run on anything that supports pythong 3. The website is fully responsive, making it adjust to the size of the screen that acces the site.
The overview, and test on colors warning/alarm
Ph graphs on chromebrowser
Same graphs in a bigger screen with higher resolution.. (shows the responsive of the graphs.. its the same data that is loaded
same graphs on the rasberry pi screen.. again same data set.
The idea is to load 3 weeks of data into the graph, and then allow the user to zoom on the graphs to see more details, here is a picture where its zoomed..
Redox graph on the pi
redox in chrome desktop computer
The graphs can be exported as png images, if you want. There is no limit on how much data you want to save. One day data, with samples every 5 min takes about 20kb of size on the system. (that is for 4 sensors)
If there is enought interest, i will make everything english, make it easy to add your probes, and remove the GHL part in the image... The project will be delived as a package, that can be run on anything that supports python 3.
