We need to use a different device api key for every single different board with a different SIM, but that is really difficult. Is there a way of doing that where you only need one single api key, and it still registers which SIM sent the data? I don’t want to have to write 1000 different versions of code for an application firmware release if there is a simpler way of get all devices to connect when they need to.
I was looking at the REST api documentation, because perhaps that might work with one master api key to use across all devices, but all the examples look like you send a json as an sms to the hologram cloud. Any tips on using that? I got a little confused. Does that incur an SMS charge?
I want to do what makes most sense for having thousands of sensors out in the field reporting.
