Turn OFF outlet using Dry the Wet Spot?

Hi guys, I am running a hydroponic system that utilizes a pump to circulate nutrient solution. I would like an App like dry the wet spot to turn the pump OFF in case of a leak. Is there a way I could modify the app to do that? Thanks!

you could modify the app.

but the easiest solution would be to just use Rule Machine and make a trigger

Yeah that looks like it’ll work. Handy for other stuff too, Thanks!
