Smoke detector (ShellySmoke) notification Home Assistant with friendly-names

Quick ‘n simple post, so I won’t forget.

Multiple triggers in one Automation, use friendly_name to distinguish entities that triggered the notification.

Using Reolink IPcams for motion detection automations in Home Assistant

Leave a comment

I’ve been testing automations using an IPCam instead of a PIR.

If dark, person detected on Reolink camera -> turn on light.

5 sensor Flame detector

Leave a comment

December is coming, time for candles.

The plan is to make a flame sensor, with in combination with my presence sensor will alert me when we leave the room and candles are on, give us a notification.

Above is the schematic. A Wemos mini (left over from another project), an analog multiplexer and a cheap 5 times flame detector.
There is a potentiometer on this board to change the sensitivity.

Search “Infrared Ir Flame Sensor Detector Fire Detection Module 5 Channel” on Aliexpress. These are 1 euro.

Presence sensor:

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

Here is some Arduino code.

#define MUX_A D5
#define MUX_B D6
#define MUX_C D7
#define ENABLE D1

#define ANALOG_INPUT A0


void setup() {
    Serial.begin(9600);

  //Define output pins for Mux
  pinMode(MUX_A, OUTPUT);
  pinMode(MUX_B, OUTPUT);     
  pinMode(MUX_C, OUTPUT);     
  pinMode(ENABLE, OUTPUT);     
  digitalWrite(ENABLE, LOW); // No need to switch, can be permanenty low
  
}

void changeMux(int c, int b, int a) {
  digitalWrite(MUX_A, a);
  digitalWrite(MUX_B, b);
  digitalWrite(MUX_C, c);
}

void loop() {
  float value;
  
  
  changeMux(LOW, LOW, HIGH);
  value = analogRead(ANALOG_INPUT); //Value of the sensor connected Option 1 pin of Mux
  Serial.print("Variable_1:");
  Serial.print(value);
  Serial.print(",");

  changeMux(LOW, HIGH, LOW);
  value = analogRead(ANALOG_INPUT); //Value of the sensor connected Option 2 pin of Mux
  Serial.print("Variable_2:");
  Serial.print(value);
  Serial.print(",");

  changeMux(LOW, HIGH, HIGH);
  value = analogRead(ANALOG_INPUT); //Value of the sensor connected Option 3 pin of Mux
  Serial.print("Variable_3:");
  Serial.print(value);
  Serial.print(",");

  changeMux(HIGH, LOW, LOW);
  value = analogRead(ANALOG_INPUT); //Value of the sensor connected Option 4 pin of Mux
  Serial.print("Variable_4:");
  Serial.print(value);
  Serial.print(",");

  changeMux(HIGH, LOW, HIGH);
  value = analogRead(ANALOG_INPUT); //Value of the sensor connected Option 5 pin of Mux

UPS Load in Home Assistant using Curl

Leave a comment

Example is for a UPS, but other generic uses can be setup in same manner.

Create helper (1-100 unit %)

input_number.uspload

Create curl command in configuration.yaml

(Fix grep/cut accordantly )

shell_command:
    getups: curl -s  "http://x.x.x.x/cgi-bin/apcupsd/upsstats.cgi?host=127.0.0.1&img1=5&img2=6&img3=5&temp=C&refresh=30" | grep "UPS Load" | grep img  | cut -f4 -d= | cut -f1 -d. | head -1

Home Assistant and Dehumidifier

1 Comment

A while ago, I bought a small Dehumidifier for my wine cellar.
I liked it a lot, so I bought another for our bedroom.

I saw some posts about people asking which Dehumidifier is supported by Home Assistant.
This one is. The “Eeese Otto Dehumidifier”

This works with the LocalTuya integration.

There are many examples how to integrate LocalTuya in HA which can be found easily using a search on the net. So, I’m not going to explain that.

I could not find a configuration example, that’s why I’ll post that part here.

Pre config:

  • Install App on phone to connect Tuya device to cloud (one time only)
    You need this to extract the localkey
  • Add a developer account to https://eu.platform.tuya.com/
    (Enable devices and change from Read to Control)
    (Get localkey from API Explorer, here is also a hint to be found about the entities)
    See below pictures
  • Install LocalTuya to HA
End result after config

Home Assistant Voice and OpenMqttGateway

Leave a comment

Yesterday I got my Home Assistant Voice!

This is a Non-Cloud solution like Alexa and Google devices.
I only could play with it for a few minutes because I was working on Arduino code with an ILI9341 Display and a BME280 (Temperature/Humidity/Air pressure).

Today I got some new goodies in, one of these is a LilyGO LoRa display which works on 433 Mhz.

I flashed OpenMQTTGateway on this device.

In the past, I posted about the RFCOM Gateway using Domoticz.
This runs on a Raspberry Pi.
While looking for alternatives, I found a rtl-sdr solution.

https://github.com/merbanan/rtl_433

Using this:

But I liked the ESP32 solution more.
Now I can dismantle Domoticz, which served me well for many years.

How cool to see realtime updates!

Note: This is a receiver device only!
But I only use read-only sensors like : Door/window, doorbell, temperature/humidity and Firesensors.

These are automatically detected in Home Assistant.

No more RFXCOM with a Raspberry.

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:

        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"
