Hello @Jbros55 ! At this time Alarm mode scheduling is not a supported feature. I'll be happy to share this with the team to reinforce the value behind it, as other neighbors have also shared interest in this. Thank you for checking and sharing with the Community!
I use Alexa routines to Arm/disarm my Ring every night/moning by voice but use Alexa routines to turn on/off several Tula plug controlled lights by Alexa timer. Also use Simple Commands by kloee to detect Ring "alarming" to turn on ights and auxiliary siren. Have not seen a single failure in the four months that I set it up. Since Alexa and some or all of these devices use wifi to communicate, maybe your wifi is "spotty" in some parts of ypur house.
There are free Android/IOS apps that check wifi signal strength. I used one to find out that I did not have enough wifi signal to operate a smart light at the far end of my basement
I just tested this and it worked. Set up a routine in Simple Commands by kloee to disarm ring. No other actions or any triggers. Create a routine in Alexa with a time scheduled and set the Simple Command routine in the Alexa routine as a "Scene". My test worked just fine. I don't personally have the need to arm/disarm Ring on a schedule but I was sure there was a way to do it. Actually, I might set up a routine to arm Ring in case I forget to do it at bedtime.
As a side note, Simple Commands by kloee has the ability to recognize when Ring is the "alarming" state and I use that trigger to activate all of my Tula smart plug controlled lights and auxiliary siren. If you do not define a trigger in SC routines, you can embed them into Alexa routines. If you define triggers, they will function autonomously and control any Alexa compatible devices. I find that S.C. by kloee adds a great deal of functionality to both Ring and Alexa
