Media control automation in HA revisited

Leave a comment

I was not happy with my old setup to control all media devices in my living room.

Controlling all devices using a single button and automations was not easy.

Problems encountered :

  1. Switching from one device to another toggled a device used by both.
  2. Switching from TV to Spotify (using my Onkyo), turned off the TV and cec turned off the Onkyo
  3. Using the Home Assistant Onkyo integration, I could select NET but not NET>Spotify
  4. The Harmony hub I’m using for Infrared Control didn’t expose all buttons.
  5. My Set-top box only power toggles. No way of reading the state.

Addressing problems:

Number 1 & 2 : Disable CEC, and manual add all that cec tried to do for me. (https://en.wikipedia.org/wiki/Consumer_Electronics_Control)

Number 5 :
(See post : https://www.henriaanstoot.nl/2024/04/01/multipurpose-rgb-sensor-esphome/)

Number 3 & 4 : Two options, integrate my web controller for onkyo.
(https://www.henriaanstoot.nl/2009/10/23/onkyo-web-control-hack/)
Or give HA more functionality.

Lets add an Onkyo python script to HA.
Open a webterminal and enter following command

pip install onkyo-eiscp

This will give you:

Mute on/off
onkyo --host 192.168.1.2 AMT01 or AMT00

Volume Level
onkyo --host 192.168.1.2 MVLQSTN

Home Assistant Shell Command example

  - platform: command_line
    switches:
      onkyo_mute:
        command_on: "/usr/bin/onkyo --host 192.168.1.2 AMT00"
        command_off: "/usr/bin/onkyo --host 192.168.1.2 AMT01"

Getting album art:

Get image from below url.
Note! .. its a static non refreshing image!

http://192.168.1.2/album_art.cgi

Note: This gives me a file which shows fine in a browser, but being a http feed you cannot embed this in a https site.
Another ‘problem’ with this image is that it includes headers, rendering this a invalid jpg when processing!
(remove first 3 lines programmatically)
I also want to have it updated, so I could make a mjpeg streamer for this.
Probably i’m going to use my reverse proxy which uses SSL offloading to access cover art over https.
(Then I can push this cover image on this webblog so you guys can see what we are listing to)

Another idea is to push this to an arduino display.

Not using https?

You can embed the album art in a dashboard. This won’t refresh, but the added time code will stop caching problems.

type: picture<br>image: http://192.168.1.2/album_art.cgi?v={{now().timestamp()|int }}")

Todo:

Make the automations foolproof.

Watching TV and want to listen to Spotify?

  1. Turn TV off
  2. Switch Onkyo to Net and Spotify
  3. (Adjust volume)
  4. Toggle TV set-top box off

etc

Next todo:
Cover art embed in HA.
Maybe in embed in this blog.
Make a small cover art display.

PHP code to strip lines and put behind a reverse proxy

<?php
header('Content-type: image/jpg');
$lines = file_get_contents('http://192.168.1.2/album_art.cgi', false);
$lines = explode("\n", $lines);
$content = implode("\n", array_slice($lines, 3));
print $content;
?>

You can use Generic Camera to refesh!

Server scripts notification for Home Assistant

Leave a comment

I’m running loads of housekeeping scripts on my servers.

I thought it would be cool to see states in HA.

Steps:

  • Log into your HA instance, and press your profile icon in the bottom left.
    Scroll to Long-lived access tokens, and create a new token.
    (Save the token string in a text file, you need it later)
  • Goto Settings > Devices & services > Helpers
    Create helper: Text and give it a name (bashnotification)
  • Next create a script in a path on your server, or place in an existing script directly.
    (Change SAVEDTOKENSTRING,HA-IP and bashnotification)
curl -s -X POST -H "Authorization: Bearer SAVEDTOKENSTRING" -H "Content-Type: application/json" -d "{\"state\": \"$1\"}" http://HA-IP:8123/api/states/input_text.bashnotification >/dev/null

I use it like this in a script

#!/bin/bash
bashnotify "Starting this script"

bash commands bash commands 
bash commands 
bash commands bash commands bash commands 
bash commands bash commands 

bashnotify "Bash command finished"

Running an adhoc command

tar czvf /tmp/test.tgz /var/www/html ; bashnotify "tarball made of www"

Today some lasercutting for Home Assistant Spotify RFID

Leave a comment

see:

Revisiting the Spotify Cube

Lasercutting a case and the playlist selectors.

Close-up RFID stickers I’m using.

Below is a test with different methods.
I like reading the booklets, so a CD i cool, and I don’t need a CD player.
(The RFID tag is in the case)
The little cards are for bought audio files I don’t have a physical CD for.

Wooden case with RFID reader being powered by external powerbank

What am I gonna do?
Cube as I had? Wooden playlist selectors as in above movies?
The cards I’ve printed?
Maybe a small record player with an RFID reader inside?

3D printed like this? https://makerworld.com/en/models/66671
UPDATE: 20240327 – Little Record I 3D printed with little groves.

I used MCE to control some Windows VMs and programs running in it in the past. (Below link and a web interface engine which on the backend converted BWW/BMW (bagpipe music files) to PDF automated comes to mind)

Web controller for Acdsee

Now, I implemented this:

https://iotlink.gitlab.io/

Controlling a Windows VM using MQTT, very nice!
(Use HA mqtt or mosquitto_pub in bash)

Question: anyone got a better solution to control programs within a VM? Let me know.

Next:

I’m creating a new case for my Wemos, LCD16x2, button, Led, Buzzer project (see other post)

I’m redesigning my previous case in blender.

But I really miss something like a generator function for different cases, like the one I made using Openscad.
Question: Anyone know a tool/add-on to generate cases?
I used a model of a wemos to get the usb connector/screw holes in place.

My spotify rfid case I will create using wooden lasercut cutouts.

In the past, I’ve controlled some blender lights using python and MQTT. But now I’m trying to control it using DMX.

Example of lighting in our living using mock-up couch and tables.

I found a cool add-on called Blender-DMX.
(B.t.w. wled can also use DMX)

Looks cool but, can I make a floorplan with this?

Blender add-on configuration

In Home Assistant I used a HACS add-on called : Art-net LED Lighting for DMX

Configuration can be done in configuration.yaml

light:
- platform: artnet_led
  host: BLENDERHOSTIP                   # IP of Art-Net Node
  max_fps: 25                           
  refresh_every: 0                      # Resend values if no fades are running every x seconds, 0 disables automatic refresh
  node_type: artnet-direct              # Which protocol to use
  universes:                            # Support for multiple universes
    1:                                  # .Nr of Universe (see configuration of your Art-Net Node)
      send_partial_universe: True       # Only send the universe which contains data
      devices:
        - channel: 1                    # first channel of dmx dimmer
          name: dmx_dimmer_rgbw         # name
          type: rgbw                    # type
          transition: 1                 # default duration of fades in sec. 
          channel_size: 8bit            # width of the channel sent to DMX device, default "8bit", "16bit", "24bit" and "32bit" 
          channel_setup: Wrgb           # This is the magic to get colors correct

It works, but I’m not happy, anyone got a better solution?

And I have to check out GDTF profiles for fixtures.

At a later stage I’m going to 3d print a white floorplan about 1cm high, with LEDs and buttons. A floorplan you can hang on your wall.

Revisiting the Spotify Cube

Leave a comment

In the past I posted about my genre selector for Spotify using a cube.

RFID music playlist genre selector.
Spotify control using python

Most was done using NodeRed and a python script.

Now, I’ve moved it to Home Assistant using a single automation.
(Maybe the Arduino sketch can be made with Esphome also.
But I don’t have time for that)
It still uses the Arduino sketch as before, which uses Mqtt to post the RFID code to Mosquitto.

Home Assistant and Harmony Hub Scripts

Leave a comment

I’ve got a Logitech Harmony Hub to IR control devices.

When adding this to your home assistant, you initially only get the Activities.

But I want to add single button presses.
I was going to re-visit my IR remote project.
(The IR blaster and the IR wemos, see previous posts)

Thanks to Duncan I had a second look at this solution

Check the files using the file editor.
Search for /homeassistant/harmony_xxxxxxxx.conf

It will show the Hub devices and their capabilities.

Short example below

My configs to set and get domoticz-433Mhz from Home Assistant

Leave a comment

I’ve posted about some integrations here:

Domoticz + NodeRed + HomeAssistant MQTT

There are three kinds of 433 connections I’m using:

  • Switches
  • Sensors (read-only)
  • Dimmers

Mqtt Home Assistant Config Yaml

Here are 3 mqtt examples using the Node-Red rewriter (see above post)

mqtt:
 light:    
  - name: "KitchenOutside"
    payload_on: "99"
    payload_off: "0"
    unique_id: "KitchenOutside"
    brightness_scale: "99"
    brightness_state_topic: ha433/kitchenoutside/brightcontrolstate
    brightness_command_topic: ha433/kitchenoutside/brightcontrol
    state_topic: ha433/kitchenoutside/brightcontrolstate
    command_topic: ha433/kitchenoutside/control
    optimistic: false
    on_command_type: brightness
 binary_sensor:
  - name: "AtelierDoor"
    state_topic: "home2/3331/payload"
    value_template: "{{ value_json.nvalue }}"
    off_delay: 5
    payload_off: "0"
 sensor:
  - name: "LivingTemperature"
    state_topic: "home/9999/payload"
    unit_of_measurement: "°C"
    value_template: "{{ value_json.svalue1 }}"
  - name: "LivingHumidity"
    state_topic: "home/9999/payload"
    unit_of_measurement: "%"
    value_template: "{{ value_json.svalue2 }}"

Here is a virtual switch sensor using curl commands

command_line:
  - switch:
      name: PatioSlinger
      command_on: >
        curl "http://domoticz:pass@192.168.1.1:8080/json.htm?type=command&param=switchlight&idx=6&switchcmd=On"
      command_off: >
        curl "http://domoticz:pass@192.168.1.1:8080/json.htm?type=command&param=switchlight&idx=6&switchcmd=Off"
      command_state: > 
        curl "http://domoticz:pass@192.168.1.1:8080/json.htm?type=command&param=getdevices&rid=6" | grep Status | cut -f4 -d\"
      value_template: >
#        "{{ value_json.result[0].Status }}"
        "{{ value_json.result[0].Status == 'On'}}"
      icon: >
        {% if value_json.result[0].Status == 'On' %} mdi:toggle-switch
        {% else %} mdi:toggle-switch-off
        {% endif %}
  - switch:
      name: DoorChimeManual
      command_on: >
        curl "http://domoticz:pass@192.168.1.1:8080/json.htm?type=command&param=switchlight&idx=9999&switchcmd=On"

Nodered mqtt payload rewriter for dimmer
Note: I still need to write the state part

Function code

var idx = 9999;
var bright = msg.payload;
msg.payload = {};
msg.payload = {"command": "switchlight", "idx": idx, "switchcmd": "Set Level", "level": bright};
return msg;

Adding a rotary encoder to Home Assistant to control dimmers using EspHome

Leave a comment

Config for mqtt-433 and home assistant entities.
Maybe I’ll add a display to select which dimmer to change.

ESPHome Config for direct communication to a MQTT enabled 443mhz dimmer.

When using GND to the rotary you have to use a pullup entry in your yaml
