Hey Roger,
the Onefinity Controller with Rev. 5 AVR Mainboard with the power pushbutton is the current model that is shipped (circuit diagram/pcb). If you attach it to a power strip, it will not come on by itself because of the pushbutton circuitry (shown here). The circuitry allows the controller to power itself off after shutdown.
But you can short J18 on AVR Mainboard and then it will stay on and be switched on and off with the power you supply. You could also retrofit the rocker switch that was found on previous models by attaching it to J18. Don’t forget to shut the controller down over the user interface though.
