Anyone know of a 2 input SPI switch?

[Burrington]

I have RGBW strips under the eaves of my house. For Christmas, etc they display RGBW colours using HinksPix controllers. But most nights I just want to have them lit up white to outline the house. Seems a waste of energy to be running the big HinksPix network when a simple addressable LED controller could do the simple "white" job. Does anyone know of a two input, 3 output SPI switch that I could use to switch between the HinksPix controller and a simple controller? I can easily DIY a 3PDT relay to do it, but thought there might be a clean ready made product to save some work.

you could try the Tester units, they are little inline controllers, you would have to select the white only option but then as power goes off and on they should be able to keep just the white

The energy to run a controller is going to be a lot less than that required to run the lights. I'd guess the controller is probably sub 10W maybe even sub 5W so it's unlikely that you're ever going to save much. If you wanted to save that 5-10W WS281x pixel latch to the latest colour so you could disconnect the output and power down the controller and at that point you've save the entire 5-10W without needing any additional power to run something else.

A relay (or three) is probably going to be the most cost effective way here.
You could use some digital switches, but they might end up being a bit more complex.
