Test Script
Not working
Buzzes properly but doesn't print when door opens and closes
from gpiozero import OutputDevice, Button
from time import sleep
from multiprocessing import Process
from signal import pause
try:
door = Button("BOARD3")
buzz = OutputDevice("BOARD5")
def buzz_loop():
while True:
buzz.on()
sleep(1)
buzz.off()
sleep(1)
def door_open():
print("Door open")
def door_close():
print("Door close")
def contact_state_loop():
door.when_pressed = door_open
door.when_released = door_close
pause()
Process(target=buzz_loop).start()
Process(target=contact_state_loop).start()
finally:
buzz.off()
HomeAssistant
Runs as a docker-compose instance with home at /home/britton-charlie/homeassistant. Remote access configured through ha.chza.me, which is a reverse proxy on the VPN server connecting to the running-lion VPN IP. Currently configured as a VPN on the 10.0.0.0/8 range.
Plex
This server hosts Plex, also within a Docker container. This is detailed in my blog post.
Plex can run very slowly as the storage is via NFS and the SQLite database doesn't like that very much. Need to see if there's a way to offload the database to local storage, e.g., on a hard drive or SD card but then it won't be redundant.
SMB Tuning
Write of an 8GB file from a MacOS device was very slow. Tried with rsync and copied okay. Might be to do with a cache of some credential somewhere but need to possibly look at creating a bootable MacOS to verify this on my own device.
Performance Tests
