Oh yay - just got an email from our sump hole. That was pretty easy.

Using a little $7 Cdn zigbee sensor. I added a little foam collar around it and sat it in the sump-pump hole. I injected a little water in to test, and the automation worked the first try.

Device is probably not intended to be immersed in water, so the foamy should keep it on the surface. The moist environment will prob result in accelerated wear and corrosion though, so may not last long.
