Node.js, git, mpc packages are required to download and work

Installing them:

opkg update && opkg install node git-http mpg123 mpc mpd-full

Download lumi:

mkdir /opt
cd /opt
git clone https://github.com/Ch-Philou/lumi-fr.git
cd lumi-fr
cp config_example.json config.json

Change the configuration file config.json Specify the address of your server, login and password

Parameter	Description
"homeassistant": true	Notify the MQTT broker about gateway devices. Helps to add devices to HomeAssistant
"tts_cache": true	cache Text To Speech files after playback
"sound_channel": "Master"	audio output channel
"sound_volume": 50	default volume
"sensor_debounce_period": 300	period for sending device status data (in seconds)
"sensor_treshhold": 50	sensor state change threshold, for instant data sending
"button_click_duration": 300	time in ms between button clicks.
"use_mac_in_mqtt_topic": true	add gateway MAC to MQTT topics

Running:

node /opt/lumi-fr/lumi.js

We check that the data from the sensors has gone and add to autorun:

cd /opt/lumi-fr
chmod +x lumi
cp lumi /etc/init.d/lumi
/etc/init.d/lumi enable
/etc/init.d/lumi start

---

Update to the latest version:

/etc/init.d/lumi stop
cd /opt/lumi-fr
git pull
/etc/init.d/lumi start

Топик	Значение	Описание
lumi/light/set	{"state":"ON"}	Turn on backlight
lumi/light/set	{"state":"ON", "color":{"r":50,"g":50,"b":50}}	Turn on highlight with specified color
lumi/light/set	{"state":"ON", "colorhex":"#00AA00"}	Turn on highlight with specified hexadecimal color
lumi/light/set	{"state":"ON", "timeout": 30}	Turn on the backlight and turn it off after the specified time (sec)
lumi/light/set	{"state":"OFF"}	Turn off backlight
lumi/audio/play/set	{"url": "http://ep128.hostingradio.ru:8030/ep128"}	Enable Radio Europe+
lumi/audio/play/set	{"url": ""/tmp/test.mp3"}	Play local sound file
lumi/audio/play/set	{"url": "https://air.radiorecord.ru:805/rr_320", "volume": 50}	Enable Radio Europe+ and set volume
lumi/audio/play/set	{"url": "STOP"}	Turn off playback
lumi/audio/volume/set	30	Change volume to 30
lumi/say/set	{"text": "Hello", "lang": "en", "volume": 80}	SAy Hello and set volume 80
lumi/alarm/set	{"state":"ON"}	Enable blinking lamp
lumi/alarm/set	{"state":"ON", "color":{"r":50,"g":50,"b":50}}	Enable blinking of the lamp in the specified color
lumi/alarm/set	{"state":"ON", "time": 1}	Turn on the flashing lamp with a frequency of 1 second
lumi/alarm/set	{"state":"ON", "count": 5}	Turn on the flashing lamp 5 times, then turn it off
lumi/alarm/set	{"state":"OFF"}	Turn off flashing lamp

Why a Fork:

• Set language to english
• Fix an issue (when settin alarm state was erased by a valu wich broke status)
• Add A Jeedom Template for easy integration
• add hex color :)

Troubleshoot

MDP

Sometime, MPD-MPC does not work properly. When you run this

mpc current --format '%name% - %artist% - %title%'

MPD error: Connection refused

and

/etc/init.d/mpd start

gaves you

mkdir: can't create directory '': No such file or directory
BusyBox v1.36.1 (2024-09-23 12:34:46 UTC) multi-call binary.

Usage: chown [-Rh]... USER[:[GRP]] FILE...

Change the owner and/or group of FILEs to USER and/or GRP

        -h      Affect symlinks instead of symlink targets
        -R      Recurse

if you cat process run:

#!/bin/sh /etc/rc.common
# Copyright (C) 2007-2014 OpenWrt.org

START=93

USE_PROCD=1

PROG=/usr/bin/mpd
CONFIGFILE=/etc/mpd.conf
NICEPRIO=-10

USER="mpd"
GROUP="mpd"

#TODO: Add uci config - nice, config

start_service() {
        local pld lport

        #create mpd directories from config
        pld=$(grep ^playlist_directory "$CONFIGFILE" | cut -d "\"" -f 2 | sed "s/~/\/root/g")
        if [ ! -d "$pld" ]; then
                mkdir -m 0755 -p "$pld"
                chown $USER:$GROUP $pld
        fi

        lport=$(grep ^port "$CONFIGFILE" | cut -d "\"" -f 2)
        [ -z "$lport" ] && lport=6600

        procd_open_instance
        procd_add_mdns "mpd" "tcp" "$lport"
        procd_set_param command "$PROG" --no-daemon "$CONFIGFILE"
        procd_set_param user "$USER"
        procd_set_param group "$GROUP"
        procd_set_param stderr 1
        # Give MPD some real-time priority
        procd_set_param nice "$NICEPRIO"
        procd_close_instance
}

Base on error return the line $(grep ^playlist_directory "$CONFIGFILE" | cut -d """ -f 2 | sed "s/~//root/g") is the problem. By the way, let's check audio_output

 aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: tfa9882audio [tfa9882-audio], device 0: 2028000.sai-tfa9882-hifi tfa9882-hifi-0 [2028000.sai-tfa9882-hifi tfa9882-hifi-0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Let's stop update param and create folder

/etc/init.d/mpd stop
mkdir "/usr/share/playlist"
vi /etc/mdp.conf

and set conf :)

playlist_directory		"/usr/share/playlist"
user				"mpd"
group				"audio"
audio_output {
        type            "alsa"
        name            "My ALSA Device"
        device          "hw:0,0"        # optional found in 'aplay -l' return
        format          "44100:16:2"    # optional
        mixer_device    "default"       # optional
        mixer_control   "PCM"           # optional
        mixer_index     "0"             # optional
}

Check all stuff

/etc/init.d/mpd start
mpc current --format '%name% - %artist% - %title%'
/etc/init.d/lumi start

\o/ No error

MQTT

Well try to connect to our Lumi with MQTT_explorer is a good way to check.
