Well, you can not unplug by software any device and they will be always plugged into your hub and drawing current. But you can stop services in OP and make devices use less current. There are services that save current because save work to the raspberry processor. Stopping access point, signal k, kplex and SDR-AIS... you can save a lot of power.
Solution, set a switch in "switches" tab, connect a toggle switch to GPIO pins and set actions stopping services to state OFF and starting services to state ON.
When analog sensors are implemented on v0.9.0 you will be able to set triggers for voltage/current and start/stop services according to its levels.
