LED Matrix MQTT Sign

keithh666 · October 29, 2019, 6:54am

I use the following for speed and intensity…

#############################################################        
- alias: Send a changed speed msg to the MQTT Sign
  initial_state: 'on'
  trigger:
    - platform: state
      entity_id: input_number.mqttsignspeed
  action:
    - service: mqtt.publish
      data:
        topic: 'cmnd/MQTTSign/SPEED'
        payload_template: '{{ states.input_number.mqttsignspeed.state }}'

And it works ? I’ll adapt my config and revert …could you test also with scroll?

keithh666 · October 29, 2019, 2:09pm

I don’t have the code for the scroll anymore as it doesn’t really work for a single width led strip.

thundergreen · October 29, 2019, 4:40pm

That’s a pity well wth your code it works perfectly now to adjust brightness and speed. Thanks a lot! Sure you cannot add the scroll just for testing?

keithh666 · October 30, 2019, 8:23am

The reason I didn’t put it back in is that you won’t have a panel long enough to read the text if scrolling left to right and the same goes for any that use vertical scrolling. Unless your text is only a couple of words long it doesn’t work.

I see I see …thanks for the explanation

Hey @keithh666

Just wanted to know where you got the code for turning the led matrix on and off via mqtt? Is it simple to change and add ? I have a esp8266 project and have connected led strips which I would like to turn on and off (led strips) via mqtt.

Thanks

keithh666 · October 31, 2019, 5:48pm

The folowing will automatically turn it off/on… you can also use the input_boolean in the front end of course…

bachoo786 · October 31, 2019, 8:38pm

No I meant the code for esp8266. Like I said it’s for my led strips project.

thundergreen · October 31, 2019, 10:18pm

Try this one https://github.com/Snipercaine/WLED-HomeAssistant

It has auto Discovery for home assistant

keithh666 · October 31, 2019, 10:36pm

The code for Arduino is in the dropbox above

thundergreen · November 1, 2019, 7:23am

Dunno if the code is the right code for a led strip …

bandric1 · November 16, 2019, 2:24pm

Thank you very much now i did it finaly Damn dupont cables :(…
Can i ask someone the display now works it displays intro message for abbout 20s then stops and restarts. Is this normal behaviour?

Than one other I can dimm the display, set speed, but cannot determine effects how to display message payload send from before doesnt work?

keithh666 · November 18, 2019, 4:47pm

It shouldn’t stop and restart - there is something wrong you will need to determine what is wrong - usually by adding the serial monitor and checking the output. I would guess at the WDT or a memory problem.

There aren’t any effects see my reply above, you need to create some automations of the type …

This is serial output:

it looks like its loosing a mqtt connection and it restarts.

I have three display with 3 node MCU-s E12 they all work like this.

keithh666 · November 20, 2019, 12:56pm

Yep that’s what it’s supposed to do as otherwise you won’t have any messages to display.

bachoo786 · November 22, 2019, 11:20pm

hey Keith

How did you manage to get Sky News working on this?

minsuke · November 24, 2019, 4:56pm

This is interesting project that I want to make.

thx for your great idea and I respect you to share this great project.

Is there another way to make it by ESPHOME ?

I want to make it like you : )

keithh666 · November 25, 2019, 12:09am

The following automation will send the news item (in this case the science feed)…

- alias: Send a templated input_text msg to the Sign Line9
  initial_state: 'on'
  trigger:
    - platform: state
      entity_id: input_boolean.mqttsign_line9
      to: 'on'
  action:
    - service: mqtt.publish
      data:
        topic: 'cmnd/MQTTSign/MSG9'
        payload_template: 'Sky Tech Feed 2 {{states.sensor.sky_tech_feed.attributes.entries[1].title}}'
    - service: input_text.set_value
      data_template:
        entity_id: input_text.text9
        value: Sky Tech Feed 2 {{states.sensor.sky_tech_feed.attributes.entries[1].title}}

You will also need the sensor…

- platform: feedparser
  name: Sky Tech Feed
