EDIT: It should be fixed now, so it won't error even if you do have multiple triggers with the same name on the same computer.

I was able to reproduce the issue with my own account by creating multiple commands with the same name on the same computer.

I'm glad you told me about this problem. I'll work on fixing it somehow.

SYNC: Request ID 7392140811546959359 update devices failed: INVALID_ARGUMENT. Detail: Duplicated AgentDeviceId.DeviceId [baseVmFsdGVy-Q2hyb21l] in device [type: "action.devices.types.SWITCH"

Did you setup the SmartThings integration with TRIGGERcmd? If you have SmartThings linked with TRIGGERcmd and Google Assistant (Google Home), and then you tried to link Google Assistant with TRIGGERcmd, that might explain the duplicate device ID error.

I've never seen that issue, but I might not have tested that scenario yet. I will test it soon, and probably build a fix soon so you don't get an error.

But, if you have SmartThings linked with TRIGGERcmd and Google Assistant, you should have all of your triggers as SmartThings devices in Google Assistant. You would have gotten a duplicate of each trigger if the TRIGGERcmd to Google Assistant link would have worked, so I recommend unlinking SmartThings from Google Assistant if you want to link TRIGGERcmd to Google Assistant directly.

Please try it again and tell me if it still doesn't work, and the time/date. I'd like to look at the server log and see if it logged anything when you get that error.

I'm also not sure whether it was a problem on the Google side or the TRIGGERcmd side yet.

Now you can say, "Hey Google turn on Youtube" to run your command with Youtube as the voice word because it created a smart home device called Youtube.
