Homeassistant integration

Can Openwrt developers help with this issue https://community.home-assistant.io/t/openwrt-dd-wrt-and-freshtomato-link-and-signal-sensors/422272.

In it's current state https://www.home-assistant.io/integrations/luci/

Basically, OpenWrt should expose more sensors to the Homeassistant integration, including

  • Traffic meter
  • Signal strength
  • Link rate
  • Link type sensors.
  • Load average
  • temperature sensors.

One could probably make a shell script / C application which uses mosquitto_pub or another MQTT client to publish data to the HomeAssistant MQTT broker every minute or so...
like the Inverter guys are doing, except we have procd and Luci :slight_smile:


that could be one solution, but since Mqtt requires another add-on to function, I think submitting a change to the LUCI integration might be a better idea.

What's stopping you doing this?

coding skills.
I am a noob when it comes to programming.
If I had the skills, I could have posted the solution for discussion instead of requesting Honroable OpenWrt developers.

@MangoMan It seems we have some trick on our hands.

working example


if you want to control mqtt through luci

@sash99 thanks, but how do I set up the collectd to publish data to Mosquito on HA?


it mentions adding the following to /etc/collectd.conf

<Plugin "mqtt">
   <Publish "name1">
     Host "localhost"
     Prefix "collectd"
     Retain true

Currently, I have Mosquitto as broker/server on HA.

Another integration via HACS


if you are using Luci collectd graghing then you need to do what i mentioned above. as Luci will overwrite collectd.conf. if you do not use luci collectd then just add to collectd.conf

<Plugin "mqtt">
   <Publish "name1">
     Host "localhost"
     Prefix "collectd"
     Retain true

collectd publishes and subs in a specific format
what database does HA use you could use to publish it to your HA data base using server in the example below to influxdb

LoadPlugin network
<Plugin network>
        Server "localhost" "25826"
        Forward false

or you write a simple script that translates collectd mqtt to HA mqtt format

example this one looking for mqtt topic called grid - when it receives one it translate to mqtt that compatible with collectd mqtt and publishes it in your case you are looking for collectd Mqtt and you want to translate to HA

#!/usr/bin/perl -w
open(SUB, "/usr/bin/mosquitto_sub -t /grid ");
while ($MQTT = <SUB>) {
system("mosquitto_pub -t 'incoming/OpenWrt/mqtt-Energy/power-grid' -m 'N:$MQTT'");

I am using luci collectd.

so in my case following code will be added to /usr/bin/stat-genconfig

function config_mqtt( c )
 local str = ""

 for s in pairs(sections) do

     for key, type in pairs({ Sub="collectd_mqtt_sub", Pub="collectd_mqtt_pub" }) do
             if sections[s][".type"] == type then

                     sname = OpenWrt4300
                     host = (ip of the Homeassistant installation)
                     user = MQTT username
                     port = 1883
                     topic = collectd/4300
                     password = top-secret password
                     pname = what should be added here? 
                     prefix =  what should be added here

                     if sname then
                             if user then
                                     str = str .. "\t" .. "<Subscribe " .."\"".. sname .."\"".." >" .. " \n"

                                     str = str .. "\t" .. "host" .. " \"" .. host .. "\"\n"
                                     str = str .. "\t" .. "port" .. " \"" .. port .. "\"\n"
                                     str = str .. "\t" .. "user" .. " " .. user .. "\n"
                                     str = str .. "\t" .. "password" .. " " .. password .. "\n"
                                     str = str .. "\t" .. "topic" .. " \"" .. topic .. "\"\n"
                                      str = str .. "\t" .. "CleanSession true" .. " \n"
                                      str = str .. "\t" .. "</Subscribe>" .. " \n"

                                     str = str .. "\t" .. "<Subscribe " .."\"".. sname .."\"".." >" .. " \n"

                                     str = str .. "\t" .. "host" .. " \"" .. host .. "\"\n"
                                     str = str .. "\t" .. "port" .. " \"" .. port .. "\"\n"
                                     str = str .. "\t" .. "topic" .. " \"" .. topic .. "\"\n"
                                     str = str .. "\t" .. "</Subscribe>" .. " \n"


                                     str = str .. "\t" .. "<Publish " .."\"".. pname .."\"".." >" .. " \n"

                                     str = str .. "\t" .. "host" .. " \"" .. host .. "\"\n"
                                     str = str .. "\t" .. "port" .. " \"" .. port .. "\"\n"
                                    str = str .. "\t" .. "prefix" .. " \"" .. prefix .. "\"\n"
                                     str = str .. "\t" .. "</Publish>" .. " \n"


 return str


and plugin section will look like this



mqtt = config_mqtt,

for plugin in pairs(plugins) do
	if (plugin ~= "collectd") and (plugin ~= "logfile") then
		section( plugin )

I don't have a file /usr/lib/lua/luci/controller/luci_statistics/luci_statistics.lua

edited /etc/config/luci_statistics and added following

  config statistics 'collectd_mqtt'
   option enable '1'

The only method which I got to work with is UPNP, still waiting on other methods

How is your mileage on that one? I tried it but looks like the connection regular drops and ha shows unavailable for the sensor for some seconds over and over again (alternating between the values and unavailable) :slightly_frowning_face:

Initially it was same as your, but has improved recently don't know why, consist connection, and so far.
I think Kvj intergration can work, if we don't use Https.

I'd like to manage everything from HA (Node-RED, in fact): disable internet access for specific devices manually/programmatically, set time(s) etc.

I wonder if there's a way to manipulate firewall rules from HA? And other stuff you can do via UCI, but in a friendly manner.

I'd imagine all firewall rules exposed as HA entities, with attributes, state, etc.

I'd use shell commands here. Just create bash scripts to manipulate the FW rules (ssh commands in the.sh files to send the appropriate action), and add them as shell commands in configuration.yaml. And then use automations to execute them at set times, and you can also create buttons to execute them manually.

This is what I have in a bash script to mount a folder from my NAS in HA:
ssh -o "StrictHostKeyChecking no" -i /config/ssl/hassio_priv_ossh.key root@x.x.x.x sudo mount -t cifs -o username=your_username,password=your_pwd //x.x.x.x/utils /mnt/utils

And then in my configuration.yaml:

  mount_nas_utils: sh /config/ssl/nas_mount.sh

Nah, that's an inelegant solution :grin: I'd much prefer an integration based on ubus, properly exporting everything.
