Home Assistant Community Add-on: Pi-hole

ludeeus · August 30, 2018, 8:06am

The message is clear, it can not find the cert file you have in the config. If you don’t have a cert you have two options.

Create a cert, and use that. (best option)
Set ssl: false in the add-on config

Sorry about, that @frenck, Do you have any thoughts on my current network problem? Despite removing the PiHole from Hass (as it broke DarkSky and Yr.no) and removing the PiHole DNS settings from my router, several of my attached devices will not “forget” about the PiHole…
I’ve tried reloading my router config file from a couple of days ago (long before the PiHole), pointing my router’s DNS to 8.8.8.8 and restarting/rebooting left right and centre.
I appreciate this problem can’t really be a PiHole problem, it must somehow be linked to my router. Just can’t understand it at the moment.

TheAMK · August 31, 2018, 8:27am

Hi, yes I get that I need to create an ssl cert but how can I do it.
I tried to search but I couldn’t find a clear instruction on how to do it,can you please help me with it:)

ludeeus · August 31, 2018, 10:27am

The easiest way is to use this https://www.home-assistant.io/addons/duckdns/
with

"accept_terms": true,

Naesstrom · September 1, 2018, 10:10pm

0.77.2 and still getting the same errors in the hass log:

2018-09-01 23:51:38 ERROR (MainThread) [hole] Can not load data from *hole: localhost:4865
2018-09-01 23:51:38 ERROR (MainThread) [homeassistant.components.sensor.pi_hole] Unable to fetch data from Pi-hole

2018-09-01 23:56:48 ERROR (MainThread) [homeassistant.components.sensor.pi_hole] Unable to fetch data from Pi-hole

Pi-hole config:

{
  "log_level": "info",
  "password": "Sup3rPazzw0rd",
  "update_lists_on_start": false,
  "admin_port": 4865,
  "dns_port": 53,
  "ssl": true,
  "certfile": "fullchain.pem",
  "keyfile": "privkey.pem",
  "interface": "",
  "ipv6": true,
  "ipv4_address": "",
  "ipv6_address": "",
  "virtual_host": "mydomain.duckdns.org",
  "hosts": []
}

And sensor config:

  - platform: pi_hole
    host: localhost:4865
    monitored_conditions:
      - ads_blocked_today
      - dns_queries_today
      - unique_clients

I can access it fine both through local IP and my duckdns adress but hass.io refuses to get any connection to it. Do I need to enter the password somewhere in the sensor config to?

berichta · September 3, 2018, 6:02am

Hi @Naesstrom,
I observe the same error in my setup. However, only in one condition. The error occurs when I reboot my whole system. After a restart of HA (only) this error doesn’t show up.
If you think about it, it seems quite logic:

After a reboot everything needs to start again. HA, and the sensor, boots faster than the Pi-hole Addon itself. At that time the sensor tries to access Pi-hole, which is simply not started yet.
After restarting HA only (e.g. for a config change), the Pi-hole addon is still running, therefore available. This is the situation where the error does not show up in my logs.

Please can you let us know if you rebooted or restarted your system at the time the logs where created?
Anyway I am afraid this will bring us into another direction: Can you disable a sensor?

WilliamHusum · September 13, 2018, 12:47pm

Hey, hope someone can help me. When I’m trying to update my blocklist I get,

[i] Status: Pending…
[✗] Status: Connection Refused
[✗] List download failed: no cached list available

I don’t know how to fix it, Pi-Hole has been working earlier, but not anymore. I’ve tried reinstalling and rebooting several times.

This is my debug log:

e[He[2Je[3JThis process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.

The intent of this script is to allow users to self-diagnose their installations. This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected. Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.

NOTE: All log files auto-delete after 48 hours and ONLY the Pi-hole developers can access your data via the given token. We have taken these extra steps to secure your data and will work to further reduce any personal information gathered.

Have you configured your Hassio device with a static IP address and an fixed external DNS server(s)?

WilliamHusum · September 13, 2018, 7:56pm

I believe so. It has worked before with the settings that I’ve got on my router now.

Eskimos · September 15, 2018, 7:16am

That is not all… there is something above that probably… usually you should look for something like FATAL:, but a lot more errors can happen.

So look above that part OR provide a full log so we can help you debug.

Hi,
After the last update, the “page blocked” isn’t showing and the DHCP feature isn’t working, how can I downgrade?

tielemans.jorim · September 15, 2018, 9:52pm

This is normal for Pi-hole v4 since they changed the (default) blocking mode. This is stated in the add-on changelog as well:

For more info about this, check out the blog from Pi-hole itself: Pi-hole v4.0 Released With FTLDNS, Improved Blocking Modes, Regex, Docker, and More – Pi-hole

Regarding DHCP, what’s not working? Please provide some more info if possible.

Never mind, I rebooted odroid and … it is working so all good, sorry for inconvenience.

Cheers

@frenck is it possible to edit the options.json file of this add-on via hassio ssh? Reason is that I only have remote ssh access to my parents network. I conducted a hassio update of the addon but since we never included a password in the original setup, it now fails to start:

[cont-init.d] 00-banner.sh: exited 0.

 We are so sorry, but something went terribly wrong when
 starting or running this add-on.

Haven’t had time to setup a direct VPN into their network.

Yep, you can use the hassio cli for that

Guys… I set a bunch of hosts in the addon config panel, but I still get the IP’s on the dashboard showing the requests. Is this normal behaviour? Shoulnd’t I be seeing the names instead?

After installing and enabling Pi-hole on my HA instance (went fine!) I am unable to use HA Cloud and also sending messages to Pushover stopped working. When I stop the Pi-hole addin everything works fine again.

I adjusted my DHCP so it sets the address of HA as DNS, my Pi is also on DHCP so it has its own DNS. Is this the issue and what is the best workaround for it? Entering static DNS?

kolossboss · September 22, 2018, 1:43pm

Yes set a static DNS like google dns: 8.8.8.8

freakstar · September 22, 2018, 5:07pm

That works great indeed!

For any other who finds this: if you are running Resin OS you can place a file (by example resin-eth0 as filename) on you SD card in the folder /system-connections/ with this content (adjusted to your needs):

[connection]
id=Ethernet
type=ethernet
interface-name=eth0

[ipv4]
method=manual
address1=192.168.2.5/24,192.168.2.1;
dns=192.168.2.1;
