Switch on/off

• Connection via ssh

sudo shutdown -h now

Wait that green led is off, then disconnect power supply.

Start-up sequence

Approximate timings:

• 4 min: to boot Rasberry Pi (under-clocked, with only 1 CPUs)
• 30 s: start WaveShare Hat
• 1 min: wait (so that peak power consumption does not coincides with GSM network registration)
• 1 min: register to GSM network and send first SMS
