Every year about this time I turn on my alert from IFTTT to bring in the plants when the temp is going lower than 40 degrees. I do this and then forget about it, but it starts alerting me around September/October. I truly love setting stuff up like this and forgetting about it so it seems my phone is a true personal assistant. As usual, I can't say enough about IFTTT. It is the simplest and best for setting up any sort of notification or routine. Give it a try.
