Display historic values in Sitemap

I use an energy consumption meter for my heating.
In my sitemap it’s displayed with:

Text item=Heating_Tageszaehler label=“Consumption today [%.1f Wh]” icon=“energy”

Now I want another line with the consumption of the last day

Text item=Heating_Tageszaehler label=“Consumption yesterday [%.1f Wh]” icon=“energy”
