[SOLVED] Wled PLEASE MAKE THIS WORK IN OPENHAB

Hardware Home Automation
1

Hello

Is it just me or wood i not be nice if this were made auto found and controllable be openhab :
Wled by QuinLED

The software is here but only for HomeAssistant :
Github

DrZzs video : about wled

If someone wood make a way to implement this in openhab that will be nice.
The hole point for me is to controle RGBWW (true light bulb coulour ) and Wled can do this ,then I will
be making some of my lights in kitchen and livingroom whit this instead of the RGB LED STRIP (Ove blue) so the wife I happy again.:grin::+1:
Im not a coder so i cant make it work ,but i`m great at following tutorials :smile:

The work here is all done by volunteers who need something added. Feel free to create a binding for this.

Uses mqtt like I do

I don’t know anything about the WLED Control system, but since they’re using standard WS2812b LED strips I can only suggest following something similar to how I control several of these WS2812b LED strips with openHAB by hooking them up to Arduinos, programming and controlling them with the FastLED library

http://fastled.io/

and wirelessly sending and receiving commands through MQTT and the MySensors library.

While this is not a plug and play solution, it allows for a much more versatile and individual control of these strips.

Both the above mentioned sites have very good tutorials, if you’re willing to dive into this subject.

Another option…

I currently use MQTT also to control WLED. Running three LED strips hooked up to some ESP-32’s.

Please find the WLED +Openhab integration +esp8266 wemos D1 Mini 4MB +WS2812 strip .
Using 4 instance of this . works really great . Lots of fetaure .

@sujitrp Quick question for you : I see temple_light_wled_col.state.toString in your items file and it is the only place where it is mentionned beside the timeline. Shouldn’t we see ganesh_strip_wled_col instead ? Is it a mistake ?

9

By the way to make it work on my end I had to make changes to the items file. All mqtt=">[mqtt:wled/godlight2: etc… and <[mqtt:wled/godlight2/ etc… had to be replaced with mqtt=">[broker:wled/godlight2: etc… and <[broker:wled/godlight2/ etc…

10

The MQTT channels will be different for different setups. Yours is mqtt1 and you broker is named “broker”. With mqtt2 the configuration will be completely different (since you now have things for mqtt2).

11

Thank you for posting your openHAB files. They have been very useful for me getting this set up on my own system. I am at a loss though on where the .js files go in the OpenHAB system. What folder do they go in?

Hi Ben good morning,

.is file to go in /openHab-conf/transform

13

thank you I shall have a play this weekend. Your information was valuable.

Hi a litle out of topic

i have a number of Magic Home LED contorlers
can i flash this frameware on that ?

or this is for smarter LEDs?

15

Hi Gad not sure on this . But you can share
Magic led item details with photo . I shall have quick check . Is it esp8266 based ?
I will recommend 1. wemos d1 mini or 2. node mcu

16

this is the current binding

somthing like this

17

Ref above link . Nice discussion and solution on analogous strip control .

Thank you i will look this up

So not really sure if this works in the current 0.85 and 0.8.6 release after they changed to the homeassistant discovery. I am new to using the transforms but will try and figure it out. Has anyone else successfully gotten this working in the current release after they changed the mqtt structure?

When using @sujitrp’s recommendation I get see event changes but all different

Hi !
Can someone please suggest changes in the items for using it with a things file in mqtt 2.4 setup. I have started late with OH and have only used mqtt2.4.

Update:
Was easy to find out. Thanks OH

Rule for the Color Picker Item

rule "Publish changes to the Color for LEDs"
when
    Item LEDStripColor received update
then
         val HSBType newState = triggeringItem.state
         val rgb = 16777215 + newState.getRGB
         val mqttActions = getActions("mqtt","mqtt:broker:brokerThingId")           // use the Thing ID for your configured Broker
         mqttActions.publishMQTT("wled/740dd6/col",""+rgb)
        
end

Works now.
Sitemap remains the same, just edit the names accordingly.

Note: I did not use the js transformation as I read some OH developer somewhere saying on the forum that running JS engine inside takes great resources on the machine. Hence I went for simpler approach instead. Thanks
