According to Ring help topics…
You can say “Alexa, disarm Ring.”
“To enable Disarm by voice, go to Alexa app, click Devices, click All devices, click on Ring Alarm and click Disarm by voice toggle on”
"Make sure Ring Alarm is linked in the Alexa Guard settings. "
However, not a single one of these 3 settings or options actually exist in Alexa or Ring. Yes, I have my Alexa linked to my Ring account. But voice control of my Ring is not possible despite claims it can.
Hi @RambosHouse. If you have a Ring Alarm you will have that option to arm and disarm with Alexa. If you have just a Doorbell or Camera you will not have that option.
If you have a Ring Alarm verify you have followed the process to connect your Alarm to your Alexa-Enabled device as shown in this Help Center article here. If you have tried this step and are still not seeing the option for the Ring Alarm, give our support team a call at one of the numbers available here. If you are outside of the US, please visit here to see how to contact support.
