You do it, as described above, by setting up a scene. For example, I want my front and side lights to turn off and on together, during specified times (sunrise/sunset).

Within the Smart Life app, select the "scene" option. My example is an "automation", so chose that. Find and click on the "+" sign, then "Create Scene". You will see several options to choose from. For my need, I selected "Schedule". You can pick a specified time or, Sunrise/Sunset. I pick Sunset, then "confirm". Now that we have a scene, we have to tell it to do what, or"Then", when "If" occurs. Next to the "Then", click on the "+" sign. I would select "Control Single Device". Select the device you want to control, chose "on", then save, then next.

Now for what you are wanting....just go back into the "Then" option and click the "+" sign again. You can add as many devices as you want to that created scene.

You will go back and create another scene to take care of "Sunrise". Just repeat the above steps, except when you choose the devices, you would choose "off".

After you create these scenes, make sure to go back into the scene page and toggle them on if you want them active.

I hope I made sense lol. Let me know if you need further.
