You are likely getting that error because you have the flag still flipped to on to create the buttons. Change it back to off and that shouldn’t happen again. It won’t remove the buttons.
The virtual buttons that are part of ADT Tools work in Action tiles. I would suggest you enable them in action tiles to change the various Alarm modes. To have action tiles know what state the ADT Panel is in you should just use the SHM tile. Once the tile is added change it so it is view only and then change the name so it shows ADT Status instead of the default. Just remember that it won’t change until the exit delay you setup in the app for Home alarm status has passed. ie if you set it to 30 seconds you will push the button and then 30 aprox 30 seconds later the status will change in action tiles to the new status.
I would also suggest you put a pin on the Disarm button in action tiles. That is a powerful dangerous button and always remember security.
