Look for help the rrd4j persistence. I believe I have it setup correctly because I have an Insteon power meter feeding data to rrd4j. I’m able to add charts to HAB Panel with historical data.
I have now added two items from the OpenWeatherMap (local temperature and cloudiness) to the rrd4j.persist file. I cannot get the weather data to graph out, no data is showing.
My power meter charts continue to update appropriately.
// persistence strategies have a name and a definition and are referred to in the “Items” section
// for rrd charts, we need a cron strategy
everyMinute : “0 * * * * ?”
everyfiveMinutes : "* 0/5 * ? * * "
everyHour : “0 0 * * * ?”
everyDay : “0 0 0 * * ?”
default = everyChange
// : strategy = everyChange, restoreOnStartup
RefrigeratorPowerMeter_KilowattHour, RefrigeratorPowerMeter_Watts : strategy = everyMinute, restoreOnStartup
LocalWeatherAndForecast_Current_OutdoorTemperature, LocalWeatherAndForecast_Current_Cloudiness : strategy = everyChange, everyminute
KitchenCeilingLights_Dimmer, KitchenCountertopLights_Dimmer, RockLamps_Group, DeckCeilingFan_Fan : strategy = everyChange, restoreOnStartup
All these items have RRD files in the OpenHAB directory but I’m unable to read them.
What am I missing here?
Thanks in advance.
