Hi @Cameron, I just saw your post, I am not sure how relevant this is and it may well be late, but I’ll offer it anyway. I got the Telstra API working with sending SMS’s triggered by the Photon (not Electron). I described it here: Garage Door Minder - SMS Alert for Garage Door Left Open This is a Twilio style of service. As far as I know it is currently free, but comes with some limitations (eg the sending SMS phone number is not constant). Not sure if Telstra offer a paid/better service than the free one.
