Is there a way of having a device turn back on after being turned off for several hours, example 4 hours, via SmartThings, Amazon Alexa or with some other type of smart power outlet?

Hi,

We have a SmartThings hub and SmartThings power outlet.

There is a device plugged into the SmartThings power outlet.

Also, we have an Amazon Echo Dot connected with the SmartThings power outlet.

There is also a Google Home in the room.

Ideally, what we would like to happen is that if someone turns off the SmartThings power outlet via the app or Amazon Alexa, that the SmartThings power outlet would turn back on after several hours, example 4 hours.

This would mean the device connected to the smart outlet could only ever be turned off for 4 hours at most.

Is there a way of configuring this via SmartThings, Amazon Alexa or with some other type of smart power outlet?

Thanks,
Robbie

That depends... on implementation...
There is WOL (which still requires an activated Ethernet adapter in a system, and one that supports Wake On Lan to turn on a system after receiving a certain packet. Some routers have support to send those WOL packets. systems like Alexa, Google, Siri could this if other systems act on it.

ARM cpus do have a wakeup timer, the CPU can be put to sleep with a time to be wokenup and can then check for certain conditions like presence of a flag-item on some system... and act on that as well.
You can look into IFTTT. That stands for if this than that. I've never used it myself, but they do have some smartthings apps that might be appropriate for what you are looking for.

IFTTT Smartthings
IFTTT is a webservice on a could system.   That will not automagically turn on & off equipment.
The equipment itself needs to be able to check there,

IFTTT will trigger on an event..., say some command is sent to it.., then it will start something else.
Knowing YOUR credentials for the other action... like: if time > 18:00 turn on light.., means if the time goes past 18:00 the tirgger fires to send the hue server @philips a command to turn on the lights in your house.

So if equipment will wake on lan (WOL) then your router needs to be snt the message to trigger WOL..., that message could be from IFTTT if you allow IFTTT full access to the modem. (and possibly half of the internet can use that as well.)

Hi everyone,

Thanks for your help.

We have a SmartThings power outlet and Amazon Alexa.

It is possible to set times for the power outlet to go on or off but not possible for getting the outlet to be turned off for a certain few hours then turn back on, i.e. if I tell the power outlet to turn off at a random time such as 11:30am, if it was set to turn on in 4 hours then it would come back on at 3:30pm.

We were wondering if any similar smart outlets would have the functionality to have them be turned off but only for a specified amount of time.

I will look into webCoRE but we were looking for something a bit simpler.

Ideally, some type of smart function like SmartThings function or through IFTTT.

Thanks,
Robbie
You want something like this:

It's a smart plug mini-meross 13 Socket. You can control it via timer/voice/remote control etc. I can control via my own web application that helps keep my plants warm.
