Counter to separate consumption (positive changes) and deliverd (negative changes)
With this counter, you can select every state of type number in the custom config. The adapter will creates 3 states internal. (cunsumed, delivered and total). consumed will be assigned, if a positive change of the subscribed state will be detected. delivered will be assigned, if a negative change of the subscribed state will be detected. total will be assigned in every case.
e.g. this adapte is usefull to emulate an energymeter with a given ergy value from a foreign device. for instance shelly will set energy of a channel back to zero in case of restart. The adapter will ignor zero and the counter value is saved for using in other adapters / scripts. The counter state will increase up from its saved value, when the shelly energy state increases next time.
