@rwhapham - No worries, you would run this python script on a device on your network, i use a raspberry pi for example…
Then call the raspberry pi via url from IFTTT
The URL is “http://192.168.1.37/Notify?Message+Goes+Here” where Message+Goes+Here is the TTS String… The + symbol is automagically converted to a space when running the TTS Library.
I had this working externally from my network using some simple port forwarding on my router.
Feel free to drop me a DM if you get stuck or message me on Twitter @3DPrintingKid
