## display item constructor
# requires all of the following parameters as input
# it requires fonts and colors to be defined
# can be called as lambda, for instance
# id(displayitem).execute(160,2,"External","size_3_label","orange",id(outside_temperature).state,1,"","size_3_value","white","°C","size_3_unit","grey","TOP_LEFT");
# this will position a block with label "External" in size 3 and color orange
# below that a value with 1 decimal, in white, size 3
# next to that unit "°C", size 3 in grey
# anchored at x,y = 160,2 top left corner
- id: displayitem
parameters:
x: int # x of anchor point
y: int # y of anchor point
label: string # label, to be shown above the value
labelfont: string # any of size_1_value, size_2_unit, size_3_label and everything in between
labelcolor: string # any of white, orange, red, green or grey

decimals: int # rounding of value to display
