@Russ Oh, yes. For now, that's exactly what I've done. I've created a routine for each command that enables the do not disturb for about 5 seconds before running the command.

This started Happening after I ve tested that field Voice/MCP Reply in the command, I use the Alexa skill for Smart Home, even I`ve deleting that field it doesn t stop threating everything as a doorbell

New Smart Home commands are discovered by Alexa correctly and execute normally, but Alexa says "Ding Dong.... Someone is in front of <device name>" for every newly created command. Older commands created weeks ago still behave correctly.
