Configuration

Hello,

On device_trackers.yaml I have:

  • platform: luci
    host:
    username: root
    password:
And I can't run this, I have this error:

How can I resolve this?

are you trying to connect to your router though ssl? You shouldn’t have to, it should just be localhost

3

yes I have SSL on openwrt. I have installed luci-ssl

4

According to the docs, you need a work around if you are using SSL:

This component requires a workaround when using luci with HTTPS and a self-signed certificate:

5

I was trying but when I enter “update-ca-certificates” I have error:
sudo: update-ca-certificates: command not found

6

If you are running hass.io, that method won’t work and you’ll need to contact the developers or open the issue back up

7

Okay, another thing. I leave luci.
Now I have UBUS.

I was doing everything from: https://home-assistant.io/components/device_tracker.ubus/
When I write: " ubus list | grep file " I have Output: file

Now, it not showing SSL problem. I have refuse it.
But now I have this error:

Somebody help me ?

do you solove it?

11

Are you using Hassio? If the answer is yes, you do not have a work around.

12

no,i use the homeassistant on ubuntu

13

Then the solution is here:

14

use this method?

I . Copy your CA cert (make sure file extension is .crt) to /usr/share/ca-certificates/
2. $ sudo update-ca-certificates (make sure you see “1 added” in the output
3. Set environment variable REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt when you starts home assistant.

The “requests” library used for making HTTPS requests to openwrt seems to bundle its own CA bundle by default and this should override the behavior.

thank you

15

I believe so, I’ve never done it. Just found it in that thread.

16

but my problem is not showing SSL problem…

Did you follow the installation guide for the RPC package for OpenWRT?

Namely:

Before this scanner can be used you have to install the ubus RPC package on OpenWRT:

opkg install rpcd-mod-file
And create a read-only user to be used by setting up the ACL file /usr/share/rpcd/acl.d/user.json.

{
  "user": {
    "description": "Read only user access role",
    "read": {
      "ubus": {
        "*": [ "*" ]
      },
      "uci": [ "*" ]
    },
    "write": {}
  }
}
Restart the services.

# /etc/init.d/rpcd restart && /etc/init.d/uhttpd restart
Check if the file namespaces is registered with the RPC server.

# ubus list | grep file
file
18

yes ,i have do that

I’ve been struggling with this since upgrading to a newer version of OpenWrt. For me what solved it was installing opkg install uhttpd-mod-ubus. I came to this conclusion because the POST to /ubus on my router would return a 404.

It would be a big improvement in troubleshootability of this code if a non 2xx return of the RPC call would be logged as an error and not some exception that something is NoneType somewhere downstream.

I have the same problem now after upgrading Open WRT from 17.x to 18.x. How did you exactly solve it? Just installing utthpd-mod-ubus? I tried that but without any result. Did you change or tweak anything else?
