I have pre paid electricity, like quite alot of users.
Was wondering if there is a way to calculate how much units we have left and display it somewhere?
My meter is in the Garage, not a big deal just to walk there every now and again to check what we have left, but it would be nice if somehow it can by display somewhere base on monthly purchase - et112 reading.
Idea is to manual entre the current reading and then it automaticly deduct what is being used.
Can it be done, is this possible?
