I have a sump pump outside that I need to run for 10 seconds, then shut off for 30 seconds and then repeat this cycle till I say stop. Can I use a GE zwave/zig bee outdoor outlet and SmartThings to automate this? How would anyone suggest doing this?
I don’t think you can get something that reacts that fast with smartthings. Only way I can think of doing what you want, reliably, would be with some type of interval relay like https://www.zoro.com/macromatic-timing-relay-24-to-240vac-12-to125vdc-7a-thr-3816u/i/G5126536/ where once its powered you can have it do intervals until you cut power.
(That linked one is a example, you’d have to do more research to find one that does exactly what you want, but I’m pretty sure that one will do it).

There are a lot of considerations to take into account for a project like this, the community has covered most of them, like ensuring the switch can handle the load, and timing limitations of the SmartThings platform.
