Home Assistant day

Leave a comment

1 – Added remote control for our media devices.

2 – Added automation for our green wall with plants in the garden
(These can be watered using a zigbee automatic valve.)

If during the day the temperature is above 25 degrees, a water drip value is turned on for 5 minutes

No code : this is too customized, interested? Mail me

Next to do .. make my cover art display using esphome.

This week, a lot of networking and Home Automation fixing

Leave a comment

(Sorry except for a mikrotik script, not much details)

  • Installed a new Home Assistant instance for testing on my Proxmox
  • Moved all dhcp/dns to my main Mikrotik, second backup in progress
  • Decommissioned an old trunked switch (lot of work)
  • Decommissioned an old router/firewall server (10+ years old)
  • Redraw my network in DrawIO
  • Installed Homelable to scan and draw my network (see below)

Meanwhile I am looking for a new welder.
Also doing some woodwork. (bird feeder stand)

Bird feeder pole (has a brownish tint now)

This is a cool project (Homelable). Below a still incomplete network.

Some code below to generate a CSV for DNS/DHCP entries from a Mikrotik.
(NOTE: seems spaces in comments/name/entries break stuff)

ssh admin@10.x.x.x "/ip/dns/static;export" | grep 10.1.0 | awk '{
    addr=""; comment="" ; name=""
    for(i=1;i<=NF;i++) {
        if($i ~ /^address=/) addr=$i
        if($i ~ /^comment=/) comment=$i
        if($i ~ /^name=/) name=$i
    }
    if(addr && name) print addr, name, comment
}' > dnsstatic.out

ssh admin@10.x.x.x "/ip/dhcp-server/lease;export terse" | awk '{
    addr=""; comment=""
    for(i=1;i<=NF;i++) {
        if($i ~ /^address=/) addr=$i
        if($i ~ /^comment=/) comment=$i
    }
    if(addr && comment) print addr, comment
}' > dhcpstatic.out

for f in $(seq 1 254) ; do lease=$(grep "10.1.0.$f " dhcpstatic.out | cut -f3 -d=) ; dns=$(grep "10.1.0.$f " dnsstatic.out | cut -f2,3 -d" " |sed s/name=//g | s
ed s/comment=//g | sed s/\ /,/g | head -1) ; echo -n 10.1.0.$f, ; echo -n $lease ; echo -n "," ; echo $dns  ;done > ips.csv

Meanwhile filling my own hosted “Spotify” clone, but better. (Navidrome)
(My immich server is also ingesting while we speak.)

Nintendo Switch controller fix, and Lora measurements

Leave a comment

One moment playing with LoRa. Next, a Nintendo Switch controller to fixed.

Side buttons or whatever you call them didn’t work anymore, so I replaced the flex PCB.

LoRa Antenna measurements

Using my NanoVNA and a RF test Kit I learned something about measuring antenna.

Below a measurement of a unknown antenna, ITs off, I need to shorten the metal spring inside.

Incorrect lenght
Better but not perfect .. yet

Raspberry Pi 5 Projects

Leave a comment

Again … out of SBCs
Where are all these things in my home. Someone is stealing Raspberry Pi’s, ESP32 and other sensors.
(Probably me)

So I’ve got multiple projects running on one RPi.

  • Dual Camera’s on top (brown ribbons), these are for VR streaming project.
  • Dual Camera’s on top. these are for a Red Light Green Light game. (Using motion detection on both camera’s for two players.
  • Below a INMP441 Mems microhone. This is a test for BirdNet recording.

All of the above are partially working. Code follows.

INMP441 is a tricky thing. I needed to do some bitbanging to get it working.

Loads of INMP441 info will be posted

Mqtt blinker for topic notifications

Leave a comment

Last year I’ve made a led pole with digital fireworks.

Giving people ability to control my Xmas lights

Time to replace for something else ..

I’ve made a mqtt 1-D game in december.

Twang with your mobile phone over the internet

I needed to change a lot to the javascript on the website to fix some stuff.

  • Fix IPhone control. (I hate iphone)
  • Fix screenlock timeout
  • Added meta refresh

The XMAS/Fireworks controller was often used, and I got notifications via my TV. (see other posts)

Now I want to see when MQTT movement when I’m in the livingroom.
So I programmed a Wemos controller to blink the internal when MQTT messages are received.

CODE:

#include <ESP8266WiFi.h>
#include <PubSubClient.h>

const char* ssid = "WIFIAP";
const char* password = "WIFIPASS";

const char* mqtt_server = "MQTTBROKER";  // MQTT broker IP
const char* mqtt_topic  = "game/tilt";

WiFiClient espClient;
PubSubClient client(espClient);

String lastPayload = "";

void setup_wifi() {
  delay(10);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
  }
}

void blinkLED() {
    digitalWrite(LED_BUILTIN, LOW);   // LED ON
    delay(200);
    digitalWrite(LED_BUILTIN, HIGH);  // LED OFF
    delay(200);
}

void callback(char* topic, byte* payload, unsigned int length) {
  String message;
  for (unsigned int i = 0; i < length; i++) {
    message += (char)payload[i];
  }

  // Blink only if topic value changed
  if (message != lastPayload) {
    blinkLED();
    lastPayload = message;
  }
}

void reconnect() {
  while (!client.connected()) {
    if (client.connect("WemosClientMqttBlink")) {
      client.subscribe(mqtt_topic);
    } else {
      delay(2000);
    }
  }
}

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
  digitalWrite(LED_BUILTIN, HIGH); 

  setup_wifi();

  client.setServer(mqtt_server, 1883);
  client.setCallback(callback);
}

void loop() {
  if (!client.connected()) {
    reconnect();
  }
  client.loop();
}
