Yep...I didn't realize all this was documented now. @mitchell.kelly93 are you able to capture what is being received by the rpi server?
You should probably consider using the pushover driver to get around the 10 SMS limit. It's an awesome notification app that is very customizable. A lot of the community have been using this for some time.
See the post below for setup details. The app would need to be purchased but it is well worth the cost. Also, the driver is now built in to HE so you do NOT need to install the code linked to in the post. The HE driver is exactly the same in terms of features.
