Building on the introduction of the new openhab-js 4.0 as presented here:
along with its documentation here:https://github.com/openhab/openhab-js/tree/v4.0.0#quantity
After standing corrected around my mixing up as much as I could of java, openhab-js, DSL notation and what not here: Working with Number:Temperature Items in rules:
I have finally upgraded to:
openHAB 3.4.2
openhab-js 4.0.0
and was trying out a few things around the simplier item notation and quantity types.
I have simplified my power generation items:
Group:Number:SUM El_Load "Load"
Number:Power El_GenPower "PV Power" (El_Load)
Number:Energy El_Yield_Year "PV Production Year"
{channel="solaredge:generic:TDI1:aggregate_year#production"}
Number:Power El_GridPower "Active Grid Power" (El_Load)
{channel="homewizard:p1_wifi_meter:GAP1:active_power" }
The Load is supposed to the sum of GridPower (positive for import, negative for export) and GenPower (zero or positive). These are apparently correctly set as quantityTypes. I was wondering, why Group:Number:SUM El_Load Item doesn’t get cast into the correct quantityType. The sum is done correctly, it just misses the unit. (console.log of item, state, numericState, quantityState, dimension, unit, symbol, float and integer of all items follows)

On a side note, I’m wondering, why the El_Yield_Year while being a correct Energy QuantityType item, has quantityState.unit and quantityState.symbol as null
