CuVoodoo #023 – forever olaf



building a power outage alert notification:
We will build a device to notify us in case of a power outage in our home. For that we just need to re-purpose a GSM tracker.

documentation watch on other devices (youtube)

Post-scriptum: do not waste any time on the Orange Pi 2G IoT.
While the idea and the hardware sound nice, after working a bit with it, there are just too many issues:

  • the official Linux distributions are old (> 1 year), the kernel is even older (it still is a 3.10)
  • the serial port is unstable (freeze on overrun)
  • the wifi is very unstable
  • the wifi MAC changes at every boot
  • the battery managment actually does not work at at all (no power and no charging due to a mistake in the design)
  • it is not supported by armbian
