Hello, i have a question. I have the TRB140 Device and i just want to use the SMS text function for server emergency SMS, the gateway has no internet connection while being connected to the server, just the SMS Service. For that i need to access the REST-API or a similar one to make it work in a nice and clean way. Can anybody help me on how to access that, im looking for many hours but havent found anything which i can use.
Greetings
