For anyone trying to use TriggerCMD to run a routine on an iPhone, you can do so using TriggerCMD, IFTTT, and iOS Shortcuts. Here is how I achieved it:
Create a TriggerCMD command of your choosing. It need not do anything.
Use that command as the "Specific Command" trigger in IFTTT
For the THEN THAT, I chose "Send me an SMS"*
In the message of the SMS type a keyword of your choosing. Create the Action.
On the iPhone, go to Shortcuts, and select Automation
Tap + to start Shortcut creation. Choose "Message"
Under "Message Contains," type in the keyword you used in the IFTTT applet
Finish the Shortcut routine you wish to run when the SMS message is received
*You could also achieve this sending yourself an email through IFTTT and choosing Email in the Automation section of Shortcuts
Using this method, I do not have to say anything to the phone or even be near it to run a shortcut on it.
