Indicating day of the week with lights?

[Ryukenden (Kevin)]

Hello,

i would like to use a wemos d1 mini in combination with a ws2812b led strip in ESPhome to indicate what day of the month it is.

This would mean 1 set of 7 lights to indicate monday-sunday. One set of 31 lights for the days, and one set of lights indicating the month.

I have 2 sensors:

  - sensors:
      dayoftheweek:
        value_template: "{{ ['Mo','Tu','We','Th','Fr','Sa','Su'][now().weekday()] }}"
        entity_id: sensor.day
 
  - sensors:
      months:
        value_template: "{{ ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Okt','Nov','Dec'][now().month-1] }}"
        entity_id: sensor.month

im missing 1 more for the day, which i dont know how to make yet.

So my overall question would be how would i write the code part in Esphome, and how to put this in a automation in HA?
Any help would be appreciated.

What sort of lights are you using? You’ll need addressables as an esp is not going to have enough GPIO’s to so 7+31+12 = 50 lights.

its a ws2812b led strip. I think you can use 1 gpio for all, as you can turn the ledstrip into segments.

light:
  - platform: neopixelbus
    id: all_leds
    name: "All LEDs"
    pin: GPIO1
    variant: WS2812X
    type: GRB
    method: ESP8266_UART0
    num_leds: 36
    restore_mode: ALWAYS_OFF
    
  - platform: partition
    id: segment_1
    name: "Segment 1"
    segments:
      - id: all_leds
        from: 0
        to: 5
    
  - platform: partition
    id: segment_2
    name: "Segment 2"
    segments:
      - id: all_leds
        from: 6
        to: 11

Basically I’m interested in this too, I’m making mqtt json lights for holidays with esphome an HA.

I think you could make effect for each day and then change it with HA automation?

And yes, you need just 1 gpio.

[Ryukenden (Kevin)]

i need 1 automation for mon-sun which i think i can use the day of the week sensor for.
the month sensor is the same.

they day is the only one that i dont know.

Im also gonna try to integrate google calander in it for appointments, birthdays etc.

[Ryukenden (Kevin)]

got a sensor for the day:

  - sensors:
      dayofmonth:
        value_template: "{{ now().day}}"

[Ryukenden (Kevin)]

does anyone know how to remove the st, th, rd, from the code?
i prefer to have just a number.

[cyn]

@Ryukenden

now().day

Try replacing your 4 lines with this:
{{now().day}}

[Ryukenden (Kevin)]

Thanks that was easy!

[Ryukenden (Kevin)]

i finished the code but it is not working. It works up to number 15 only.
Could it be that the d1 runs out of memory?

[nickrout]

How are you testing?

[Ryukenden (Kevin)]

I edit the sketch and add 1 more “partition number” untill it stops working. I plug it in a wall socket after to make sure its not a power issue.

[nickrout]

So is that a compile error?

[Ryukenden (Kevin)]

it uploads fine, after the reboot of the chip that is what shows in the log
