For my fish tank I have develop one new module for data persistence with relative widget able to plot the data on a chart.
I’m not a coder and I'm newbie in HG, probably is possible optimize the code and add new error control.
I have used "rrdtools" (http://oss.oetiker.ch/rrdtool/ (http://oss.oetiker.ch/rrdtool/) ) a little "vintage" library but very light and fast (run fine on my hold raspberry)
Features
- Make and manage rrd database for any sensor enabled with this data:
- Current day with 1 minute of data resolution
- Last week with 5 minutes of data resolution
- last month, resolution 20 minutes
- last year, resolution 5 hours
- Makes available one virtual module for any sensor enabled with:
- Value
- Unit of measure
- Small chart
- Control buttons for data range visualization
- Popup menu with large data chart
Compatibility and limitations
- At the moment GenericMonitor is compatible with a sensor module, I test it with MCP3008 Analog Input Module but probably run fine also with My Sensor but I don’t test it:
- The name of Sensor can’t contain special character, the only character managed is " ", sorry but with python I was not able to encode/decode the name of module, at the moment I only substitute " " with "%20"
- Widget was designed to work with "C" theme (light grey)
- The database is updated every Heartbeat time for every sensor managed, system write some data whenever on flash memory, this is not very good for the flash memory life, I suggest to use one different location for system and database (i.e USB flash stick), is possible configure the path of database on ChartModule setup.
Install
sudo apt-get install rrdtool
cp monitor.png /usr/local/bin/homegenie/html/pages/control/widgets/homegenie/generic/images
cp chart*.png /usr/local/bin/homegenie/html/images
- install program and widget on home genie
- Chart_Monitor.hgx
- homegenie_generic_monitor.zip
- Open the setup page for sensor module and check “Enable Chart Module”, fill all other parameter:
- Unit of mesure
- Min Max: set the range of value, warning, if the data run out of this range will be void
- Heartbeat is very critical, I recommend set this value as a double or triple of the data sampling.
- Now restart the ChartMonitor for build the databases.
I'm waiting feeback, Thank You

Hi,
Is there a link to the HG source code?
Thanks!

I think it is in the .rar file.
