Hola Folks… first time poster… I did read through other threads on this topic but it still seems to be a problematic challenge. I have a pantry with a door open switch… my family of course leaves this door open all the time so the light is always on. I have not been able to get them to change their behavior, so I trying to solve it with technology.
I previously looked for ‘smart bulbs’ that would turn off after a preset amount of time… these actually exist (10 minutes is the shortest time that I have found… however they are incandescent and $20 each + shipping.
I received a Smartthings hub for my BDay and promptly set up a socket to my Espresso machine so that it automatically turns off 15 minutes after it is turned on… works great.
Now, back to the original challege… how to turn the pantry light off after something like 3 minutes of it turning on.
I do not have a neutral and the light socket obviously only gets 120V when the door is open. I guess the best way I can actually see this working is to make the switch on the door permanently closed to ensure the light socket has 120V… then put a SmartBulb in there, then add a motion sensor in the pantry to do the dirty work.
Downsides to this approach are…
- Battery in the motion sensor
- Needs ‘smarts’ to even turn on
Isn’t there anything that when power applies, that the light is ON by default and would tell the SmartHub it’s status (on ON) which would then let me turn it off with a smart app timer?
Has anyone else solved this problem or worked through it already? I would be curious to hear your stories. Otherwise, I will start experimenting and replying here with my results.
thanks in advance…
