+Machine Interface
+Querying Complex Conditions Quickly
+<&recipe>With the increasing complexity of multiblock machinery, keeping track of their needs becomes quite complex.
+While <link;redstone_wiring;comparator signals;probe> can provide some insight into the amount of items inside, only the Machine Interface can provide a more detailed evaluation and send redstone signals.
+
+When placed against the redstone control surface of a multiblock, opening the GUI will allow you to configure a variety of conditions by which to output a signal.
+Press the "Add Condition" button to add a new row. Within that row, the first button serves to delete it again, the second one is for configuring the signal color to output on.
+This is followed by two dropdown menus, one for selecting the type of check (such as "Machine Active", "Item Input", "Fluid Output") and one for selecting the condition.
+Most checks support "Comparator Output" for a signal strength that is scaled to the items/fluid/energy stored. But you can also choose from true or false options, such as "75% Filled" or "Empty".
+As soon as a condition is matched, the Machine Interface will output the relevant signal on the configured color-channel to any attached <link;redstone_wiring;Redstone Interface Connector;bundled>.
+
+In addition to sending, the Machine Interface can also receive a redstone signal and output it to the connected machine. The signal color for that is configured in the bottom-right-hand corner of the GUI.
+This allows you to make use of the <link;logic_unit;Logic Unit> to evaluate the signals coming from the machine and then send one back to enable or disable it!
