Hi - maybe someone smarter than me can help as I’m having no luck. I have a simple plug-switch (Jasco) and I have one of those radiator-heaters plugged into it. I’m trying to setup logic to leave the heater on during the daytime (8:30am-10:30pm). Between 10:30pm and 8:30am - I’m trying to setup an automation routine to turn the plug-switch on for 15 minutes and then off for 15 minutes. This would cut the usage by 50% overnight - and I can vary the off-time as needed if I want it warmer or cooler overnight. I can get the start/stop logic to work pretty simply in the automation-routine. But once I add logic to have the time limited to 10:30pm-8:30am - everything seems to stop working. I have 3 routines setup to try to accomplish this: 1 - at 8:31am - turn on the plug-switch. 2 - at 10:31pm - turn off the plug-switch. 3 - If 10:30pm-8:30am (next day) - every day precondition. and if plug-switch is off for 15 minutes then turn on plug-switch and set turn-off after 15 minutes. The code works fine turning it on/off every 15 mins - but once I add in the 10:30-8:30 time constraint it never wakes up. Unsure what to do next on this - I could have written a Groovy smart-app to handle this but now prefer (need to) use the supplied automation-routine interface. Thanks. ---

I have tested it with 1 minute **on** and another **off.** check that in the third automation, that the plug condition **off** for 15 minutes, **it is not a precondition.** You can also try turning **off** the plug a little later than 10:31 p.m. since the shutdown time starts counting from the first shutdown after 10:30 p.m. or try period 10:25 p.m. to 8:30 a.m. next day ---

Or try fast Automations. I have selected random times. ![Screenshot_20211112-065719_SmartThings](https://global.discourse-cdn.com/smartthings/original/3X/4/d/4de22a8d01ec973a11ada904806a287af63f58dd.jpeg) ![Screenshot_20211112-065817_SmartThings](https://global.discourse-cdn.com/smartthings/original/3X/b/9/b9933de57c0eb67a079222be1b874121375ef67d.jpeg) ---

Hi - thanks very much for the replies and suggestions - however it seems my hub may have needed to be restarted or something similar. We had a hard power-failure here which took us offline for a long time. After power was restored and the hub came back up - the automation now seems to be working just fine. Maybe there was something residual in the hub from earlier attempts at trying this? Either way - I’ll know to restart my hub before I throw up the white-flag when what should work doesn’t. Thanks again.
