It could be great to have a shortcut directly on a device to turn it on for a certain amount of time.
I know this is possible to achieve that with Automation, but it’s not convenient.
My idea is that you touch your light, or your AC, or whatever device, and you have a shortcut to turn it on for x minutes. It could create an automation behind the scene and delete it once the task is done.
Smartthings have something similar in their app
When you go on a light you can set a timer to turn it off after x minutes / hours. It’s just one touch.
I think it’s something really missing from HA.
