I set a timer on Ultracron this morning when I was trying the dehydrator out and that worked well. But, it would be nice to have something automatic so I can run overnight rather than having to make sure I'm around (and awake). I'm primarily running Asian pears from my trees and they take ~4 hours. That's just long enough that if I set it up after dinner I'm requiring I stay up past when I would want to typically. I had a cheapo dehydrator this summer that worked pretty bad. It didn't have a grounded plug so the timer I bought was just the cheapest one I could find and it worked ok. If no suggestions are available, I'll just get a grounded timer like posted and run a timer on my phone.
