Home Assistant and Harmony Hub Scripts

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

{
    "Activities": {
        "-1": "PowerOff",
        "42652474": "Watch TV",
        "43054933": "Squeeze",

        "43557114": "Kodi",
        "49494467": "Tv on",
        "52476284": "Boxon",
        "52476285": "Boxoff"
    },
    "Devices": {
        "Google Chromecast": {
            "commands": [],
            "id": "67134460"
        },
        "LG TV": {
            "commands": [
                "PowerOff",
                "PowerOn",
                "PowerToggle",
                ".",
                "-",
                "0",
 -----------8<----------------------------- SNIP SNAP
               "SportsMode"
            ],
            "id": "67134658"
        },
        "Onkyo AV Receiver": {
            "commands": [
                "PowerOff",
                "PowerOn",
 -----------8<----------------------------- SNIP SNAP
                "VolumeLevelUp5Step"
            ],
            "id": "67134459"
        },
        "arcadyan DVR": {
            "commands": [
                "PowerToggle",
 -----------8<----------------------------- SNIP SNAP
                "TV"
            ],
            "id": "67134775"
        }
    }
}

Lets create a Script for this

See the IDs above to refer to commands below.

alias: Netflix
sequence:
  - service: remote.send_command
    target:
      device_id: 7e82a825decabedbc98a0b5ce2ac5d78
    data:
      num_repeats: 1
      delay_secs: 0.4
      hold_secs: 1.2
      command: PowerOn
      device: "67134658"
  - service: remote.send_command
    metadata: {}
    data:
      num_repeats: 1
      delay_secs: 0.4
      hold_secs: 0
      command: InputStb/Dvr
      device: "67134459"
    target:
      device_id: 7e82a825decabedbc98a0b5ce2ac5d78
  - service: remote.send_command
    metadata: {}
    data:
      num_repeats: 1
      delay_secs: 0.4
      hold_secs: 0
      command: Netflix
      device: "67134658"
    target:
      device_id: 7e82a825decabedbc98a0b5ce2ac5d78
mode: single

Add these scripts to buttons

type: entities
entities:
  - script.allmediaoff
  - script.netflix
  - script.tvon

Kodi camera stream push playlist

Below is a solution when you want to stream IP camera’s in Kodi/Libreelec .

You can push these commands using Nodered, Bash script or whatever.

First make some camera scripts in your profile directory.

Examples:

# Kodi on Linux/Raspberry
# Place a file cam1.m3u in .kodi/userdata/profiles/(kodiprofile)/playlists/video/
rtsp://admin:secretpass@192.168.1.123:88/videoMain

#and another one in cam2.m3u (another example mjpeg example)
http://192.168.1.124:8000/stream.mjpg

#For windows it is in
C:\Users\(Username)\AppData\Roaming\Kodi\userdata\profiles\(kodiprofile)\playlists\video

Enable http access in Kodi and run the playlist using curl

curl -i -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"Player.Open","params":{"options":{"shuffled":false,"repeat":"off"},"item":{"file":"special://profile/playlists/video/cam2.m3u"}},"id":"1"}' http://KODISERVERIP:8080/jsonrpc

A bash loop script

while true; do
curl -i -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"Player.Open","params":{"options":{"shuffled":false,"repeat":"off"},"item":{"file":"special://profile/playlists/video/cam1.m3u"}},"id":"1"}' http://KODISERVERIP:8080/jsonrpc
sleep 10
curl -i -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"Player.Open","params":{"options":{"shuffled":false,"repeat":"off"},"item":{"file":"special://profile/playlists/video/cam2.m3u"}},"id":"1"}' http://KODISERVERIP:8080/jsonrpc
sleep 5
done

What to do when waiting for your ribs on the smoker. (Programming some python)

This time I used a rub with the following ingredients:
Seasalt, garlic, brown sugar, mustard seeds, paprica, cilantroseeds, black pepper, red pepper, oregano, thyme and cumin.

Doing a simple 3-2-1 smoke session, so .. what to do in dose 6 hours?

Lets make something using a Sense hat and Python.
Same HAT I used for my xmas ornament thingy in our tree.

  • Generate a large maze (80×80 for now)
  • Paint the maze using colors on the SenseHat
  • Read joystick movement and scroll the maze accordingly, keeping the player in the middle

Now I have to paint my ribs with BBQ sauce, and leave it in the smoker for yet another hour. (Nice glazing)

Next steps for the maze:

Use a better way to generate (reverse backtracking as I made for my other maze thing)

Wall collision detection is nearly completed.

Better placement “birth” of player in the maze.

Waveshare Epaper ESPHOME and Mqtt Notification over secure mqtt

UPDATE: AccessPoint on Arduino implemented with captive portal for Wifi Configuration

Got my Waveshare Epaper Cloud running on ESPHome

This is a Epaper display with a 2000mAh Lipo and a passive buzzer.
Running parts of my Smoker monitor.

MQTT Notifier over Internet

This is part of a test where my friends and me can have notifications LEDs over the internet.

Using certificate parts from:
Controlling the led will be done using Mattermost webhooks, or slashcommand with custom scripting.

Last week’s stuff

Update: https://www.henriaanstoot.nl/2024/01/14/hlk-ld2410b-with-a-wemos-mini-d1-v4-connected-to-home-assistant-using-esphome/

Case for presence detector

Update: BBQ watch

Not posted in the past, new version using ESPHOME and a m5stickc

Previous version using a ESP12
A “watch” with core and environment temperature of my smoker with a alarm, and button for timers.

ESP32 dac’s drawing on oscilloscope ( no additional components)

ESP32 in front of scope, two clips for x and y

For above i used sin/cos functions 2:3, which creates LissajousĀ figures.
See: https://www.henriaanstoot.nl/1992/01/01/oscilloscope-graphics-using-a-amiga-bonus-vectrex/

3 battery operated buttons (no wires needed) to control my shelly dimmer at the dinner table.

left button on, middle steps per 20% and 3rd button off.
(This cheapass button only sends ON commands)

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

I’ve posted about some integrations here:

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: "Ā°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

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

Home Assistant Speech and More

I made my own Mqtt to speech thingy in the past.
Sending a text to a mqtt topic would be picked up by my domoticz raspberry and using a bash script the topic payload was converted to speech and being played on a connected speaker.

This speaker migrated to my Home Assistant NUC.
So i changed the speech engine.

Beside this migration, i’ve started using the HA voice assistant capabilities.
This was a major impact/project in 2023.

I’m not going to talk about configuring this .. There are many good YT tutorials and forum topics about this.

https://www.home-assistant.io/voice_control/thirteen-usd-voice-remote/

This is the device: a ESP32 pico, Microphone, leds and Speaker are being used for this sound assistant.
(It uses ESPHOME)

Back to the speaker being hooked-up to my HA NUC.

Install the addon PicoTTS (speech synthesis)

configuration.yaml

# Text to speech
tts:
  - platform: picotts
# My part
input_text:
  mqttspeech:
    name: mqttspeech
    initial: ""
    

Then install notified addon

Add a text field to your dashboard …

HLK-LD2410B with a Wemos Mini D1 (v4) connected to Home Assistant using ESPHome

LD2410 is a high-sensitivity 24GHz human presence status sensing module developed by Hi-link. Its working principle is to use FMCW frequency-modulated continuous waves to detect human targets in the set space. Combined with radar signal processing and precise human body sensing algorithms, it realizes high-sensitivity human presence status sensing, and can identify human bodies in motion and stationary states. And auxiliary information such as the distance of the target can be calculated.

This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area, and output the detection results in real time. The farthest sensing distance can reach 5 meters, and the distance resolution is 0.75m. Provides a visual configuration tool, which can easily configure the sensing distance range, sensing sensitivity in different intervals and unmanned delay time, etc., to adapt to different specific application needs.

Support GPIO and UART output, plug and play, and can be flexibly applied to different smart scenarios and terminal products.

There are 3 versions: Without Bluetooth, with Bluetooth (B version) and a C version which uses the standard pin distance.
The other ones are a pain in the *ss to solder!

Got a Bluetooth version? See end of post!

When searching for examples, I noticed that many had issues getting this working.
Let me be clear, it wasn’t working for me the first time.
Things i’ve learned:

  • Flash the first initial ESPHome using a USB cable, after that you can connect the module and flash OTA
  • Do not use the standard Uart RX/TX, it didn’t work for me. And messes-up the logging over USB (See baudrate: 0 to turn this off)
  • When connecting D7/D8 and this signal gets pulled down, the wemos won’t boot. (Running wifi connections gets interrupted)
    This is also a sign that RX/TX is switched around!
  • Measure and make sure you have a good, stable 5V power to your LD2410

Here is a post about the RCWL-0516, a similar project, but this one can’t measure distances and person detection won’t work when a person is not moving.

https://www.henriaanstoot.nl/2022/11/14/radar-module-rcwl-0516-with-mqtt/

Steps to take:

  • Flash ESPHome over USB
  • Detect and add using Home Assistant
  • Edit and upload code (below)
  • Connect the sensor

Wire it up like this:

Bluetooth:

I’ve connected this HLK-DL2410B to Home Assistant before using Bluetooth. But I wanted to get them connected using Wifi.

You can install a App on you phone to connect to the sensor when powered on.
This way you can test the device, but also upgrade the firmware and make adjustments!

Just enable engineering mode and click more.

Testing another baud rate and upgrading the firmware:
