looks better than a 2U sheet of black steel imo, and more fun

i used x24 max7219digit matrix in 2 lines of 12, hot glued onto a sheet of 2U cut sized 50% black tinted acrylic, which was lying around from another project, each matrix display one of 10 random 8x8 png's, i initially did it by using HA sensor data but it had quite an impact on HA and the esp to get the speed of updates i was after, so opted for just random

I was using HA to munge loads of sensor updates into one sensor with an automation, I think it was flooding recorder until I stopped it, anyway it was a temp solution to better things

That should be done on the ESP, then you wouldn't have that problem. But if you prefer this method, then it's doesn't matter anyway.

will definetly do the same project !

#

with the idea of the animation speed adjusted by network data troughput from the router

#

idea:

#

use a ld2450 or other microwave human presence sensor

#

so it react to nearby humans 🙂

now thats an idea, if i can fix the issue for updating esphome on it

#

Hey All, I have some code that worked fine, until i updated esphome, and now i dont know how to sort the problem so i cant update the board. any help appreciated

display:
  - platform: max7219digit
    id: display_max
    cs_pin: 15
    num_chips: 24
    num_chip_lines: 2
    chip_lines_style: snake
    rotate_chip: 0
    scroll_enable: False
    update_interval: 16ms
    intensity: 0
    lambda: |-
      if (id(lcd_page).state == "WOPR") {
        static display::image *wopr_array[] = {
          id(wopr_01), id(wopr_02), 
          id(wopr_03), id(wopr_04), 
          id(wopr_05), id(wopr_06), 
          id(wopr_07), id(wopr_08), 
          id(wopr_09), id(wopr_10)};

        int n = rand() % 10;
        it.image(0, 0, wopr_array[rand() % 10]);
        it.image(8, 0, wopr_array[rand() % 10]);
        it.image(16, 0, wopr_array[rand() % 10]);
        it.image(24, 0, wopr_array[rand() % 10]);
        it.image(32, 0, wopr_array[rand() % 10]);
}

image:
  - file: "wopr/01.png"
    id: wopr_01
  - file: "wopr/02.png"
    id: wopr_02
  - file: "wopr/03.png"
    id: wopr_03
  - file: "wopr/04.png"
    id: wopr_04
  - file: "wopr/05.png"
    id: wopr_05
  - file: "wopr/06.png"
    id: wopr_06
  - file: "wopr/07.png"
    id: wopr_07
  - file: "wopr/08.png"
    id: wopr_08
  - file: "wopr/09.png"
    id: wopr_09
  - file: "wopr/10.png"
    id: wopr_10```

i now get the error

```/config/wopr.yaml: In lambda function:

         static display::image *wopr_array[] = {
