EDIT: For the moment at least I am suggesting that the relays may not be ready for prime time. I got a sticking relay with an LED lamp at 0.3A. May have had a large inrush current. In any case don't follow my lead on this until I find a more reliable board or switch to SSRs.
--------------------------------
I've modified a used Furman RP-8 power conditioner to switch and ultimately to sequence power to my Behringer studio monitors. The original Furman RP-8 has a lot of available space inside. I installed a Raspberry Pi 0w along with a RelayPlate which has seven relays each switching 1A at 120VAC using relays that are rated for 3A. Everything is enclosed in the metal chassis and the relay board is designed to be safe for single point failures.
The relays are controlled by a supplied Python program that sets up a web server on the Raspberry Pi. WiFi access is from a browser on a desktop or tablet/phone. I plan to make some minor changes to the program to allow sequencing the power when a HW organ loads. I'll be learning whether the setup is reliable as I go along, but for now this looks like a nice, dependable setup.
I believe the relays will work fine. If they don't hold up it would be possible to operate larger relays or SSRs from the same board. The ribbon cable is disconnected in the photo. Wiring is 14ga solid copper with soldered terminals. There is one outlet that comes on with the power switch and seven that are remotely controlled.
