KNX Weather chart with more values

Try to get two values (outside temperature and wind speed) in one chart. It works with single charts (One for temp and one for speed) but not combined together.


Group gChartTempWind
Number WS_Aussentemperatur "Außentemperatur [%s °C]" <temperature> (gChartTempWind) {knx="<9.001:6/6/10"}
Number WS_Wind_km "Wind speed [JS(windspeed.js):%s]" <wind> (gChartTempWind) {knx="<9.005:6/6/30"}
Number Weather_Chart_Period

#sitemap (Only the code for the combined chart)

Switch item=Weather_Chart_Period label="Außentemperatur & Wind" icon="sun_clouds" mappings=[0="Day", 1="3 Days", 2="Week", 3="Month"]
Chart item=gChartTempWind period=D refresh=600000 visibility=[Weather_Chart_Period==0, Weather_Chart_Period=="NULL"]
Chart item=gChartTempWind period=3D refresh=3600000 visibility=[Weather_Chart_Period==1]
Chart item=gChartTempWind period=W refresh=36000000 visibility=[Weather_Chart_Period==2]
Chart item=gChartTempWind period=M refresh=36000000 visibility=[Weather_Chart_Period==3]


Strategies {
	// for rrd charts, we need a cron strategy
	everyMinute : "0 * * * * ?"
Items {
	WS_Aussentemperatur, WS_Wind_km : strategy = everyMinute, restoreOnStartup
	RTR_Buero_Ist_Temperatur, RTR_Buero_Soll_RM_Temperatur, RTR_Buero_Stellgroesse : strategy = everyMinute, restoreOnStartup


TempChart5min.items=WS_Aussentemperatur, WS_Wind_km, RTR_Buero_Ist_Temperatur, RTR_Buero_Soll_RM_Temperatur, RTR_Buero_Stellgroesse

Here is the result.

Not sure, but maybe you have to persist the grouped items by using

gChartTempWind* : strategy = everyMinute, restoreOnStartup

even if this will result in the same persistence files.

Tried it before and right now. No effort.
Did it as you have it described in the other topic.
Don’t have a clue.

No idea.
Would like to solve this issue before copy it to the other room temperatures.
