Battery backup and standby modes???

[afboundguy]

I am about to get the new batteries for my battery coralbox battery backup and after organizing my RKE setup and it got me thinking about how I can use the battery backup while still using the standby mode?

I know there was an RK module that had the DC pump 3 prong cable (DCI I think) but short of that I was curious how I would go about doing that short of unplugging the powercord from the controller but that negates the benefits of having a standby mode.

I was curious if I could make my own relay and do a module myself and somehow tie it into the 3 pronged power cords for my Jebao pumps and to it into one of the spare 0-10v ports on the other modules.

Basically make it so the power changes on the 0-10v port during said standby modes that will shut the relay off during standby mode cutting power/signal from the controller head to the pump
