Just got this installed and working along with Big Talker. Was pleased to find the alarm’s “BEEP” command works with my SHM Delay smartapp, creating the CHIME sound 
Is there any way to serialize or queue multiple commands (other than Smartapp command delays) so that subsequent commands execute after the completion of the prior command?
For Example http://192.168.0.108:1035/?ALARM=CHIME&SPEAK=hello&@DONE@
What currently occurs (for me) is Chime and “Hello” speech occur simultaneously, I want the chime to sound and complete, followed by the speech.
Also tried the following without success http://192.168.0.108:1035/?ALARM=CHIME&WAIT=TRUE&SPEAK=hello&@DONE@
Also same result for multple commands found in manual
http://192.168.0.108:1035/?SPEAK=@|ALARM=CHIME&SPEAK=Hello%20daddy&@DONE@
