I'm reading a power consumption device with 2 clamps for solar production and my power consumption.
I have good readings and the problem is a array problem. I would like to subtract my Consumption minus solar production.
I have made a join node that gives me an output with 2 arrays (screenshot)
Then I used the node node-red-contrib-calc and there I made a subtraction.
My 2 arrays are called in debug node 0 and 1
So it needs to subtract ARRAY 0 from ARRAY 1 and here is the problem. Sometimes its ok and sometimes it switches ARRAY 1 first and then ARRAY 0 so my result is different.
Is there a way to get array0 always first?
In my dashboard screenshot at that moment it was ok. And when you see the chart you see it switched.
I hope I'm clear...
