Arm / Disarm with Alexa?

I have my system up and running, and I have it linked with Alexa.  I can ask Alexa status of doors, etc, but can't seem to get it to set the alarm or disarm.  How do I use Alexa to arm and disarm the alarm and have a voice pass code to disarm?

I'm interested in the same idea.  It appears that Alexa has disabled the konnected devices for "security reasons" unless you have the ADT Hub and ADT modules.  It would be nice if Konnected had an Alexa Skill to possibly overcome this issue?

I have the same issue

3 years, and still no response for this? I have the same question

 If you are using Samsung Smart thing, you can create scene to arm and disarm. These scene will be visible to Alexa app, which can be controlled using voice.
