[slawekjaranowski]

Expected Behavior

Value read from discrete (relay) register should be represented by Number item as
1 (one) - for on state
0 (zero) - for off state

Current Behavior

Value read from discrete (relay) register by Number item is:
-1 (minus one) - for on state
0 (zero) - for off state

Context

Showing on state as minus one maybe confusing.
