I searched for a packaged power control relay. I found this controlled power strip. The control input operates from 3-48VDC or 12-120VAC. It has 2 normally open outlets, 1 nomally closed, and 1 always on. It controls up to 12 Amps. This avoid the need to work with high voltage wiring.

This could be used to control the power to the bricks. The brick outputs could be monitored with optocouplers and a few other components, plus a reset switch. The input resistance of the control terminals is not specified. Based on examples it does not require much input current.

The price is $27 at site is https://dlidirect.com/products/iot-power-relay. Could be useful for other applications. It can be used with an Arduino for example.
