I'm considering a large deploy of the FiPy. I have deployed 10k plus of other IoT devices and am quite aware how difficult it can be to have all of the correct reconnection scripts in place to assure the device stays online and does not need a technician to go onsite and fix the device if it goes offline. Can anyone speak to how well the FiPy is at staying online and reconnecting or rebooting on errors or disconnections? I'm currently running on AT&T in the US. Its been running for a day and its still online.
