ActionTiles's SHM Tile is not compatible with the "new" Smart Home Monitor in the not-ready-for-primetime "Samsung (Connect) SmartThings App". We do not have an ETA for compatibility, if ever.
We have not been provided with an API specification for SHM in the new App. We're disappointed that SmartThings did not change the name of this Feature to help avoid this confusion.
We (and other experienced long-time SmartThings customers) recommend that all SmartThings Customers use the SmartThings (Classic) App indefinitely, rather than use the incomplete "new" App.
This KB Topic will be updated when we have any relevant new information or plans.
