Blue/Red Series 2-1 Compatibility with 12v Transformers

@PJF were you able to configure your Red Series 2-1 to trailing edge?

I found instructions at the link below but the button combination doesn’t seem to do anything. Red Series 2-1 Firmware Changelog | VZW31-SN

I also tried setting parameter 26 from within Hubitat, but the log tells me parameter 26 is undefined. Log entry:
