I use a program/app/skill... whatever they're calling it now... Called YONOMI to make things work the most seamlessly. Funny thing is, if you use it, you won't even know it's there... it appears all of it is done by the Alexa and the Hub. Once you have that , you can go into the hub settings and set up an activity and with YONOMI can set up routines based on TIME. Kinda complex but it does work. I don't use any timers to turn anything but lights right now, so mine are all done through the Philips hUE app... and I really only use one as my wife likes to go to sleep with a colored light on and I can't deal with it if I wake up in the middle of the night, so I have a timer set to turn it off after she is asleep (which doesn't take but about half an hour)... Lots and lots of strategies to get what you want done, and so much of it is free like an eagle... including the Yonomi app/skill... look it up in the Alexa info on your computer or phone and set it up. I think the skill is computer doable and the actual app is phone based only.
