You have asynchronise “bug”.

You Set Electra Meter Eind as first, but Homey runs it asynchron (all at once, not in a sequence).  
So 3 cards later (the 4th condition card) you allready use the Electra Meter Eind tag, while it probebly will not have ben set yet!

You should increase every actioncard with a one-second-more-delay-then-the-previous-card.  
That way it will be executed in sequence (mostly, not always tho, if your Homey is busy for example).

(Or use the [H.O.O.P. (Hope) - Homey Object Oriented Programming](https://community.homey.app/t/h-o-o-p-hope-homey-object-oriented-programming/43709) App which i created to solve this kind off problem (you can choose to execute the Actioncards synchronised (sequentuel).
