I just released an app/driver combo to fit my need for dashboard arming/disarming of HSM and changing modes.
You can choose to not require a code for any of the actions when configuring the app, and only use the buttons you want on a dashboard. The buttons to change HSM and modes also have a switch which can be used to trigger automations in Rule Machine or Alexa/etc.
Im not sure if alexa can trigger button pushes, but if so, you can expose the buttons to alexa and use that to run any of the commands in my app.
