LED Matrix MQTT Sign

#154

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 …

- alias: Send a templated input_text msg to the Sign Line 0
  initial_state: 'on'
  trigger:
    - platform: state
      entity_id: input_boolean.mqttsign_line0
      to: 'on'
    - platform: time_pattern
      minutes: '/10'
  action:
    - service: mqtt.publish 
      data:
        topic: 'cmnd/MQTTSign/MSG0'
        payload_template: 'The Current Bitcoin Price is {{ states.sensor.market_price.state }} USD'
    - service: input_text.set_value
      data_template:
        entity_id: input_text.text0
        value: 'The Current Bitcoin Price is {{ states.sensor.market_price.state }} USD'
        
- alias: Turn Off templated input_text msg to the Sign Line 0
  initial_state: 'on'

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.

#157

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

#158

hey Keith

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

#159

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 : )

#160

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
  feed_url: 'http://feeds.skynews.com/feeds/rss/technology.xml'
  date_format: '%a, %b %d %I:%M %p'
  inclusions:
    - title
    - link
    - description
    - image
    - language
    - pubDate
  exclusions:
    - language

I’m afraid I know nothing about ESPHome :frowning:

#162

Thanks Keith.

I used the feedparser custom component but I get the following [object] issue. What version is your feedparser?

I use 0.0.6 but as far as I know it always looks like that unless you break out each object as shown above.

#164

you mean in the automations?

#165

@keithh666 I got it working thanks but is there anyway were I could show all t he titles available from Sky Tech Feed? so instead of entries[1].title maybe entries[0].title?

#166

@keithh666 entries[0].title gives the title of the first news only and not all the available news.

#167

There isn’t a synopsis, you could create one with a for loop or just list them all out as it tells you how many there are.

#168

How can I just list them out mate?

#169

Where n is a number between 0 and the number of items-1

You would have to ask someone that knows templating better then me to work it out tho’.

I got tthe wemo to flash with keithh666’s files - thank you.

But the order of the matrix display is out of sync.
its a 8x8 4 modules on a connected PCB.
The displayed text starts a=n the 1st 8x8 then scrolls to #4–>#3 -->#2
so the order is #1–>#4–>#3 -->#2

do i need to change #define MAX_DEVICES 12 ?
or connect the 3 pin on the other side (#4 8x8 module)
AliExp - MAX7219 dot matrix module microcontroller module 4 in one display

#173

Then you have 4 devices :slight_smile: each 8x8 module is a device. The pins can only be connected one way as it says on the underside input on one side to output on the other for connecting another set of devices.
