+description: A sub-plugin for PSUControl. Adds a momentary option to PSUControl power controls that sends a signal for a
+  brief time rather than continuous. Useful for bistable relays.

+A sub-plugin for the PSUControl plugin that allows using bistable relays for power control. It implements
+the same mechanisms as PSUControl, so it requires python periphery to be installed, only it pulls the GPIO
+up/down only momentarily and then returns it to the default state.
+
+### Instructions
+
+- Set the PSUControl Switching Method to "Plugin" and select "PSUControl MomentaryGpio Plugin" from the dropdown
+
+- Then in the PSUControl MomentaryGpio Plugin settings screen, set the appropriate GPIO Device, PIN, and pulse time in
+milliseconds.
