Yes so I want to keep the Node on-line all the time and then anyone who needs it would be able to use it, both as a mesh node, but also as an SMS uplink. I don’t really fancy leaving a phone attached but a cheap raspberry zero is small, cheap and lower powered enough that I could easily run both from a solar panel and battery.
In order to do this, we need to understand the details of the Pro SMS sending. Which I guess GoTenna aren’t going to share as it would allow people to by-pass the monthly license fee.
The fee I’m guessing is covering the cost of the SMS messaging and licensing of the off-line maps.
