I'm using NextCloud from the guide here and it's working really well. I've got an external 500Gb laptop drive in a cradle fixed with blu-tac under a Pi3. It just sits against the wall at the back of my desk, working well. How are you backing up photos from your iPhone to the OwnCloud? That sounds like a good thing to see if I can do with the NextCloud.

There is an Owncloud app on the app store for both iphone and android which connects to the same wifi network and you can upload selected photos and tell it to upload as soon as the picture is taken. It works well.

It's taken me a while to set up the external hard drive but I've got it done now so it working nicely :).

Well it's done, Pi Zero W with a relay.

GgU4Ots.jpeg

The power to the router goes through the relay, I just broke into the power cable.

It boots and checks the internet connection every ten seconds, if all is good, the green LED flashes briefly. If it fails to get a response within two minutes, it triggers the relay for ten seconds which drops power to the router. It then sleeps for four minutes to allow the router to restart and reconnect to the internet and then starts checking again.

The relay isn't energised normally, the connection the router goes through is normally closed so I can restart the Pi without causing the router to drop out.

I'm very happy with this. This is the first time I've done anything with the GPIO and although I found some simple Python code to check the internet, I've tweaked the whole thing to work as I want, including the LED flash each time the check is successful.

I did have a problem where the relay would trigger on reboot and it took me a while to work out what was actually happening. The Pi was booting and starting my Python routine before the WiFi had a chance to connect and so it was seeing what it thought was an internet drop and going into the reboot routine. A simple sleep command in the appropriate crontab entry to just wait fifteen seconds before starting was a nice straightforward fix.

In my mind, this is what the Pi is all about, thinking of something it can do and then finding a way to do it. This only occurred to me on Wednesday afternoon and now, three days later, I've done it!

I like that, I like that a lot.

My router occasionally throws it's toys out of the pram and won't reconnect, some times it's the wireless network that falls over (two teenage boys, poor wireless gets hammered) other times it's the wan connection. Would you be kind enough to post your code up for a look see? I'm thinking about building it into the pi I already use for pivpn and pihole (still working flawlessly too :) ), that's connected to the wired network but I could add a wireless dongle and then ping over wired and wireless to keep an eye on both....

No problem. I found the base code online and tweaked it a bit. I know it's really simple stuff but it's the first time I've done anything with Python so I'm quite proud of what I've done.

check.py
Code: 
import urllib2
import RPi.GPIO as GPIO
import time

RELAY = 21 #RELAY PIN, physical pin 40
ALIVE = 20 #LED PIN to flash LED on live internet, physical pin 38
CHECK_EVERY = 10 #Seconds

GPIO.setmode(GPIO.BCM)
GPIO.setup(RELAY, GPIO.OUT)
GPIO.setup(ALIVE, GPIO.OUT)

# Force both outputs low
GPIO.output(RELAY, GPIO.LOW)
GPIO.output(ALIVE, GPIO.LOW)

def flash_ok():
    GPIO.output(ALIVE, GPIO.HIGH)
        time.sleep(0.2)
        GPIO.output(ALIVE, GPIO.LOW)


def internet_on():
    try:
        response=urllib2.urlopen('https://www.google.de', timeout=240)
        print "Internet OK"
          flash_ok()
        return True
    except urllib2.URLError as err: pass
    print "Internet ERROR"
    return False

def reboot_router():
    print "Rebooting Router"
    GPIO.output(RELAY, GPIO.HIGH)
    time.sleep(10) #Energise relay for ten seconds
    GPIO.output(RELAY, GPIO.LOW)
    time.sleep(240) #Wait for four minutes for router to reboot

while True:
    if not internet_on():
        reboot_router()
    time.sleep(CHECK_EVERY)

GPIO.cleanup()



watchdog.sh
Code: 
#!/bin/sh
# watchdog.sh
# Changes into watchdog directory and runs the python script
cd ~/watchdog
sudo python check.py &

In crontab:
Code: 
@reboot sleep 30 && sh /home/pi/watchdog/watchdog.sh > /home/pi/watchdog/logs/cronlog 2>&1

The two files sit in ~/watchdog and in there I've also created a logs directory.

The code itself should be fairly self explanatory. Don't forget to chmod +x them both.

I can hear you saying "why is he using google.de to check?"

Well I run Pi-hole. I don't want the URL I'm checking to be in the Top Domains list on the admin page so I simply picked a site which should always be there and added it to the Pi-hole settings so that it won't appear on the list. You could choose anything really.

Whats the best way of remotely controlling a Pi from a window machine?

Pi1 - raspbian and pihole (both up to date) currently running, accessing over network via a windows 10 pc.

I've done it before but it created an instance on my machine and didn't change anything on the actual Pi. Someone suggested another way of doing it but I can't remember what it was.

If I'm not using putty and I want to use a GUI then I use RealVNC (https://www.realvnc.com/raspberrypi/). If I can set it up then you shouldn't have any problems :).

Wasn't sure whether to post this in this thread of the official Kodi one.

Has anyone tried the Edimax EW-7811UTC AC600 with LibrELEC? I'm hopefully getting whole network wired on Monday so for now I'm still stuck with wifi. Libre detected it straight away (or at least it detected my wifi SSID) so I connected to the 5ghz channel I have however having run a speedtest I'm getting like 10Mbps. I am using a VPN and have both desktop PC and Pi connected to same VPN yet my PC upstairs get's my estimated broadband speed (50/10) which makes me think it's a problem with the device or the driver. The router is in the hallway which leads to living room where my Pi is but in Libre the signal strength is only 50%.

Not too clued up on my Linux commands but two I'm familar with are lsusb:

Code: 
Bus 001 Device 004: ID 7392:a812 Edimax Technology Co., Ltd

Considering purchasing a pi3. Can someone clarify something for me though as I'm struggling to understand the concept of these devices.

Can I have one pi that runs:
- kodi
- retropie
- pokemmo app


Do these applications work on top of an already existing OS that you install, or are they essentially their own OS? I'd like to be able to use it like a regular computer and just boot up whichever app is required at the time, kodi, retropie etc..

They are usually installed on an SD card and boot straight in to kodi etc. I would buy 3 SD cards personally, but there may be a different way :)
