Poročanje o izpadih 220V napajanja

 

 - z optosklopnikom - modul z AliExpressa:
  https://vi.aliexpress.com/item/32809745991.html
- na malino, gpio18
- bash skripta vsaki dve sekundi preveri pin18 in pošlje (za Kuk):
  1 izpad elektrike: https://net.hamradio.si/220v?callsign=S55YGV&event=220v&value=Off
  0 vklop elektrike: https://net.hamradio.si/220v?callsign=S55YGV&event=220v&value=On

 

Skripta 220v.sh, ki teče na RPi in poroča o izpadih: (zamenjaj 'znakmanjse' s tem znakom)

Skripto registriramo, da se požene ob zagonu maline:


  - sudo nano /lib/systemd/system/monitor-220v.service

    (ustrezno popravi pot do skripte)
