How to turn on WLED via automation

[Vendo232]

Team

I would like to simply turn ON and OFF my WLED strip in automation calling for specific effect.
turn on Rainbow for 1 min for example

9 Rainbow Displays rainbow colors along the whole strip

So to turn ON Rainbow

action:
    service: mqtt.publish
    data_template:
      topic: [Device Topic.. XYZ ]/Segment/switch/set
      payload: on
      topic: [Device Topic.. XYZ ]/Segment/fx/set
      payload: 9

and to turn OFF

action:
    service: mqtt.publish
    data_template:
      topic: [Device Topic.. XYZ ]/Segment/switch/set
      payload: off

Do I have it right?

How would you setup “RANDOM” effect to be turned ON?

[TinyDoT]

It goes a little something like this:

Turn ON

action:
  - service: mqtt.publish
    data_template:
      topic: wled/all/api
      payload: T=1

Turn OFF

action:
  - service: mqtt.publish
    data_template:
      topic: wled/all/api
      payload: T=0

Change Effects

action:
  - service: mqtt.publish
    data_template:
      topic: wled/all/api
      payload: FX=?

Replace ? with 0 thur 82

And, for random, you need to create a random sensor like this:

sensor:
  - platform: random
    name: Random Effect
    minimum: 0
    maximum: 82

Once you have that created, now you need an automation

alias: Random WLED Effect
trigger:
  - platform: time_pattern
    minutes: "/10"
action:
  - service: mqtt.publish
    data_template:
      topic: wled/all/api
      payload: FX={{ states("sensor.random_effect") }}

This will change the Effect every 10 mins. I hope this clears things up.

Thank you million time Sir.!!!

Sure thing, glad I could help.

DrZzzs has some automations and input selects to do this posted on github:

GitHub - Snipercaine/WLED-HomeAssistant: Some flows to use nodeRed to control...

I used them to create this and can post the Lovelace config if you want it.

WLED no discovery

I just noticed this collection of files for adding presets and pallet control to home assistant: https://github.com/Snipercaine/WLED-HomeAssistant but have not had a chance to delve into it yet. Is Node Red required or will the automation.yaml file do everything? Edit: answering my own question, no NodeRed is not required. Nearly everything is working. Just the palette selection seems to be non functional. [Screenshot_2019-10-25%20Home%20Assistant] EDIT2: Fixed it. I’ll submit a PR but for …

Note that the PR has been merged so the ones on github are correct now too.

EDIT: also note that Home Assistant can now control WLED natively via a core integration.

I’m trying to implement this but don’t seem to be able to pass the effect through MQTT… any ideas. Thanks.

    platform: time
  action:
  - service: light.turn_on
    entity_id: light.wled
  - service: mqtt.publish
    data_template:
      topic: wled/all/api
      payload: FX=10

Hi Paul, I think yu are close,but we have to change the way that you are turning the wled light strip on, give this a try:

- id: taskLightTest
  trigger:
  - at: '23:44'
    platform: time
  action:
  - service: mqtt.publish
    data_template:
      topic: wled/all/api
      payload: T=1
  - service: mqtt.publish
    data_template:
      topic: wled/all/api
      payload: FX=10

And the next question would be how do I turn them off:

action:
  - service: mqtt.publish
    data_template:
      topic: wled/all/api
      payload: T=0

I hope this helps.

Hey, thanks for the response on this. I tried what you mentioned but didn’t seem to work. Hmm…

this worked but I suppose I need to use mqtt to send the payload?

@paulfecht, if your Homeassistant is up to date, then you can integrate Wled as an integration and you would not have to use MQTT at all .

[pollinolas]

I had it with mqtt before but I have changed it for integration, much more comfortable, I only use mqtt to change the effects with a random sensor

@TinyDoT

Home Assistant

thanks I’ll check it out.

[Bas_Fpv]

Someone have it working with Nodered?

[TinyDoT]

@Bas_Fpv, check out @tom_l post above, Snipercaine has a Node-Red config there.

I’d like to add something since I’m not seeing it anywhere else. Doing this doesn’t require any custom cards. Just vanilla HA, HA helpers, HA automations and official wled integration.

You can use the state of an input select helper or input select integration (in config.yaml) then add helper to a card in lovelace to easily change the effect. Helpers can be used via automations on all wled attribute states that are available with service calls. Also input select helper state can be set from wled attribute state when effect is changed by some other means such as changing a preset or changing the effect in wled web ui. Again this can be done for all wled attributes exposed in home assistant.

Here are my automations for controlling wled. I made a separate one for each but I’m sure this could be done more elegantly.
