I want to set a timer for a switch so that it turns off after being on for 20 minutes. I thought I'd be able to do that in Simple Automation app, as I have done in Smartr Lighting in ST. However, I can't find that option - the time options I see are to use a specific time of day, or sunrise/sunset, no relative timer option.
I find Rule Machine a bit clumsy for a simple rule like this, like killing a fly with a bazooka. I'll give those a look...I have been using HPM, but sometimes forget to browse it when I'm looking for a capablity. Never had anything as nice on ST for finding community apps...
