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 Lissajous 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: "°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;

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 …

433mhz sensors and Home Assistant

I’ve got a lot of wifi sensors in my home automation.
But also the ones i’ve started with.
The 433mhz temperature,pir and doorsensors.

These are all connected to Domoticz via a rfxcom gateway.

I’ve previously posted about previous setups.
https://www.henriaanstoot.nl/2022/11/03/home-assistant-and-433-dimmers/
https://www.henriaanstoot.nl/2022/11/17/domoticz-nodered-homeassistant-mqtt/

The setup i’ve ended up with is this:

Under hardware in domoticz install the mqtt broker.
Configure your mqtt server (mine is mosquitto)
Add devices to floorplans to send these to Mosquitto

Now i can see the topics in MQTTExplorer

Install the home assistant websocket palette in NodeRed

Configure the nodes like above

These are some example flows (I’ll put the function code below)

Above are the NAMED entities in Home Assistant

CODE

//Code for NR temperature filtering on domoticz IDX
//A door censor uses nvalue instead of svalue1
//Humidity can be svalue2
//Check the Mqtt payload in MQTTExplorer which to use!
var varidx = msg.payload.idx;
var varnvalue = msg.payload.svalue1;
if(varidx == 3108)
{
msg.payload = {};
msg.payload = varnvalue;
return msg;
}

Example of the trigger node.
When a temperature sensor battery dies, and no new data arrives- in 1 hour, I get a pushover warning. (use pushbullet/email/TV notification whatever you want)

Domoticz + NodeRed + HomeAssistant MQTT

UPDATE 20240122 : below

I’ve got my RFXCOM connected to my Domoticz, and not connected to my HA.

RFXCOM 433 Mhz

To have the changes of my IOT devices being known to HomeAssistant I wanted to use mqtt.

Domoticz writes the mqtt topic (payload) like this
(topic: domoticz/out)

{
	"Battery" : 100,
	"LastUpdate" : "2022-11-17 18:21:59",
	"RSSI" : 6,
	"description" : "",
	"dtype" : "Temp + Humidity",
	"hwid" : "4",
	"id" : "230E",
	"idx" : 8461,
	"name" : "Living Temp/Hum",
	"nvalue" : 0,
	"stype" : "Cresta, TFA TS34C",
	"svalue1" : "20.0",
	"svalue2" : "60",
	"svalue3" : "1",
	"unit" : 1
}

So you can’t see which device it is by the topic name, the idx is in the json (8461)

To get this device ( a temperature sensor) into HA using mqtt i rewrote the mqtt topic using NodeRed

Temperature Humidity Sensor

NodeRed flow

    }
]

The function node code ( rewrites the mqtt topic)

var varidx = msg.payload.idx;
msg.topic = "home/"+varidx+"/payload";
return msg;

Now we have a idx separated payload “home/IDX/payload”
(The other entries svalue/nvalue are from testing.

Adding the MQTT entries to HomeAssistant configuration.conf

mqtt:
 sensor:
  - name: "LivingTemperature"
    state_topic: "home/8461/payload"
    unit_of_measurement: "°C"
    value_template: "{{ value_json.svalue1 }}"
  - name: "LivingHumidity"
    state_topic: "home/8461/payload"
    unit_of_measurement: "%"
    value_template: "{{ value_json.svalue2 }}"

Now i can add the card to the dashboard.

This should now be a generic mqtt translator

A quick update:

Adding a motion sensor:

Home Assistant
  - name: "LivingMotion"
    state_topic: "home/45/payload"
    value_template: "{{ value_json.nvalue }}"

Add sensors to be reset to the switch node

UPDATE 20240122

I’m using domoticz as a 433->mqtt bridge, and some virtual devices i can toggle with curl (bash scripts)

I needed to make a custom 433 door sensor in Home Assistant with toggles to OFF after a few seconds. (There is NO off signal in this cheap sensor i’m using)

I’m changing the payload complete, to have a payload which matches the device class for door: (state with on/off)
It was nvalue = 0/1

(Whenever the IDX changes, I only have to update this Nodered part)
HA won’t notice the change.

var nvalue = msg.payload.nvalue;
msg.payload = {};
if(nvalue == 1)
{
msg.payload.state = "ON";
return msg;
} 

AND after 5 seconds

msg.payload = {};
msg.payload.state = "OFF";
return msg;

Old skool Home Automation & GPC

The date of this post is when we worked on GMC’s GPC, but i’ll post some other own made hardware related to domotica.

GPC Original Page: https://gpc.metro.cx/gpc/README

This DIY home automation was written by GMC in C.
Later we made little microcontroller prints, which could control/switch lights and more.

PIC16x84

We uses GPASM as assembler

One of my schematics
What is this?
=============

 This is the Global Premises Control package. It is intended to be a
complete solution to the DIY home automation. It provides you with a
daemon which will centralize all control functions, and some custom
programs for sound, remote control and things like that.
 The first steps to realizing the goal was made by Koen Martens. He wrote
the first daemon and made the first support programs. Other people got
interested and ported the GPC package to their homes. Since then it seemed
wise to coordinate development to prevent from having three different
versions of the package. It is currently under development and is far from
complete.

History
=======

 15-03-98 - The first initiative
	    With the help of Henri Aanstoot and Marco Geels the first
	    cables were mounted in the ceiling at Waalstraat 136. This
            involved re-dedicating some high voltage lines for the low 
	    voltage used by GPC equipment.
	    The next few days Koen Martens spend his time writing software
	    to switch on the lights (which was not possible without
	    software anymore :). This software was very rudimentry and 
	    did not feauture the daemon yet.
 28-03-98   Version 1.0 was born.
	    The need for a global way to control the premises arose, and
	    Koen Martens decided to write a daemon which would control the
	    input and output lines, with support programs for the logic.
	    This resulted in global, the gpc daemon. 
	    Running on different servers there were programs to control
	    lights and lightswitches (light_control), sound (sound) and
	    the alarm clock (wakeup). 
 10-06-98   Version 2.0 (r0.2.0) was born. 
	    The support programs containing any logic had vanished,
	    instead the daemon had all the logic encoded in it.    
 03-07-98   Version 2.0 still.
	    - Added remote control receiver code.
 29-11-98   GPC r0.3.0
	    - Started coordinated development
 11-12-98   GPC r0.3.1
	    - Security support included, providing a (basic) interface
	      for protecting variables with passwords on a security level 
	      clearance basis.
	    - Global notify protocol added, clients can now register one
	      or more variables. This makes the old (0.3.0) polling method
	      obsolete thus reducing the network load dramatically.
	    - Logging library added.

			  DEC Writer
			  WYSE terminal
			  The 486 linux machine has the daemon, and is 
			  hooked up to the premises.
			  The P60 has a sound card and a RC receiver.
 - Lip-on-ice
	Location	: Lipperkerkstraat 321, Enschede, Netherlands
	Site coordinator: Willem-Jan Faber AKA aloha AKA xtz ( And Henri Aanstoot AKA Fash)
			  (w-jfaber@freemail.nl)

			  Four occupants (3 male, 1 female)
			  Connected to three other premises.
			  Computer list not yet in!
			  
 - Venom
	Location	: P. Mondriaanstraat ??, Almelo, Netherlands
	Site coordinator: Sebastiaan Smit AKA venom (wssmit@freemail.nl)
	Site description: Three floor house
			  Three occupants
			  4 computers

 If you would like to join the development, mail me at gmc@freemail.nl.


In progress
===========

 The following projects are in progress right now:
	- A script language to describe the control logic for the daemon
		Koen Martens
	- An cgi interface for the http connectivity
	- Support for sharing variables on multiple daemons

Usage
=====

 Use is for your own risk. We can not be held responsible for any damage
resulted from running any of this software.
 Keeping that in mind, usage is very simple but work needs to be done on
the documentation :)

DIY door sensor using a bend CDROM and a sensor i got

I’d would send a signal to our computers and playing a sound sample on our sound system. Also a IRCbot named (lampje) would mention “Backdoor open” in our own channel. (We where running our own IRC servers, interconnected .. because we can. A average of 3 Clients per server sound the way to go .. LOL )
Lampje the IRCbot also controlled the livingroom light and more.
